Tesla has filed a new patent for “Parallel Processing System Runtime State Reload,” comprising of a system of three or more processors working in conjunction to effectively eliminate the possibility of hardware failure during the use of Autopilot or Full Self-Driving. The patent outlines a robust system of parallel processors that can operate in the event that one of them fails or experiences a runtime state error. “Should one of the parallel processors fail, at least one other processor would be available to continue performing autonomous driving functions,” the patent shows.
The patent was filed and published on August 26th and comes just a week after the company’s Artificial Intelligence Day event that was held last Thursday. Outlining a system of at least three processors operating in parallel, it is monitored by circuitry and can locate and identify if one of the three parallel-operating processors is having a runtime state error. The circuitry will then identify a second processor to switch to in the event of a runtime error, access the runtime state of the second processor, and load the runtime state of the second, operational processor into the first processor, which is experiencing a runtime error.

Tesla describes the patent in detail:
“A system on a Chip (SoC) includes a plurality of processing systems arranged on a single integrated circuit. Each of these separate processing systems typically performs a corresponding set of processing functions. The separate processing systems typically interconnect via one or more communication bus structures that include an N-bit wide data bus (N, an integer greater than one). Some SoCs are deployed within systems that require high availability, e.g., financial processing systems, autonomous driving systems, medical processing systems, and air traffic control systems, among others. These parallel processing systems typically operate upon the same input data and include substantially identical processing components, e.g., pipeline structure, so that each of the parallel processing systems, when correctly operating, produces substantially the same output. Thus, should one of the parallel processors fail, at least one other processor would be available to continue performing autonomous driving functions.”
Technically speaking, the autonomous vehicle needs only one processor to function as described in an accurate fashion. However, these processors can be overloaded with data when loading into the Neural Network and could experience short-term and non-permanent operational errors. When this occurs, the system would then switch to one of the other processors for normal operation, with at least two backup processors in this patent, as it repeatedly mentions a series of three.

The second processor would then activate and load the runtime state into the first processor to make the primary processor chip operational once again:
“Thus, in order to overcome the above-described shortcomings, among other shortcomings, a parallel processing system of an embodiment of the present disclosure includes at least three processors operating in parallel, state monitoring circuitry, and state reload circuitry. The state monitoring circuitry couples to the at least three parallel processors and is configured to monitor runtime states of the at least three parallel processors and identify a first processor of the at least three parallel processors having at least one runtime state error. The state reload circuitry couples to the at least three parallel processors and is configured to select a second processor of the at least three parallel processors for state reload, access a runtime state of the second processor, and load the runtime state of the second processor into the first processor.”
The purpose of this patent is to continue system availability, even when the primary processor is experiencing functionality issues due to overuse. The two additional processors essentially act as “backup” and can determine whether autonomous driving systems are meant to be enabled if the first processor experiences an error. “With one particular example of this aspect, the parallel processing system supports autonomous driving and the respective sub-systems of the at least three parallel processors are safety sub-systems that determine whether autonomous driving is to be enabled.”
FIG. 13 is a timing diagram illustrating clocks of the circuits of FIGS. 8 and 10 according to one or more other described embodiments. As shown, the runtime state (data1) of first processor/first sub-system is determined to have at least one error. In response to this determination by the state monitoring/state reload circuitry, the signal st_reload1 is asserted to initiate the loading of runtime state (data2) from second processor/second sub-system into the first processor/first sub-system. With the embodiment of FIG. 13, a first clock (clk1) is used for the first processor/first sub-system and a second clock (clk1) is used for the second processor/second sub-system. There exists a positive skew between the first clock (clk1) and the second clock (clk2), resulting in a late cycle of the loading of the runtime state (data2) of the second processor/second sub-system into the first processor/sub-system, potentially resulting in errors in the runtime state reload process.

It also appears that this patent aligns with Tesla CEO Elon Musk’s previous description of the Dojo self-driving Supercomputer, which was detailed at AI Day. To increase the accuracy and encourage the parallel operation of the processors, the system will utilize a clock input to calibrate the two processors, increasing the accuracy of the system.
Tesla has focused on accurate FSD operation and has revised its strategy on several occasions. After moving to a camera-only approach earlier this year for the Model 3 and Model Y, the company is experiencing more accurate FSD operation through the harmonized processing of its eight exterior cameras. The operation of internal processors, which are responsible for compiling, compressing, and sending data to the Neural Network, can fail temporarily, so the presence of backup processors to continue comprehending self-driving data is a positive idea.

Tesla Cybercab is the company’s autonomy-geared automobile that will eventually begin the phase-out of human drivers. In recent days, however, there has been speculation regarding the vehicle’s equipment and whether it would be fitted with a typical steering wheel and pedals.
CEO Elon Musk put an end to this discussion, at least for now, as he maintains the vehicle will not have anything that would remotely resemble any possibility of any sort of manual operation.
The problem is, there is a flaw in his logic, and his justification for the reasoning is an opinion. But Musk has a special ability; he has the final say on what goes on at Tesla, and if he does or doesn’t want manual controls in the new vehicle, he’ll get his way.
On the All In Podcast on Friday, Musk gave his final answer to whether the Cybercab would have a steering wheel or pedals by stating it would not when the production units start rolling off lines in Q2 2026.
He provided a further explanation:
“The reality is, people may think they want to drive their car, but the reality is that they don’t. How many times have you been in an Uber or Lyft and said ‘I wish I could take over for the driver, get off my phone, and drive to my destination? 0.0 times.”

Although the units that have been spotted on public roads in recent days are equipped with a steering wheel and pedals, it is because Tesla is testing the vehicle in real-world situations, and manual controls are required for it.
Tesla Cybercab spotted testing on public roads for the first time
Some Tesla fans in the community have said that the car seems more geared toward being suitable for manual operation as opposed to a fully autonomous vehicle primed for driverless ride-hailing.
Earlier this week, Tesla Board Chair Robyn Denholm said that if the company had to put a steering wheel or pedals into the Cybercab, it would.

SpaceX sets the record straight on Jim Bridenstine and Artemis 3
SpaceX argued that Bridenstine’s comments should be taken with a grain of salt as he is working as a paid lobbyist for companies that are competing for NASA contracts.
SpaceX pushed back firmly against former NASA administrator Jim Bridenstine after he questioned the agency’s reliance on Starship for the Artemis 3 Moon mission.
In a detailed thread on X, SpaceX argued that Bridenstine’s comments should be taken with a grain of salt as he is working as a paid lobbyist for companies that are competing for NASA contracts.
Bridenstine’s comments on Starship and Artemis 3
Bridenstine and fellow former NASA chief Charlie Bolden noted during a recent symposium that NASA’s current Artemis strategy is approaching zero chance of beating China to the Moon. Bridenstine expressed skepticism that NASA’s current architecture, which is expected to use Starship to transport astronauts to and from the lunar surface, could succeed in time.
“Starship is a tremendously important vehicle for the future,” Bridenstine said, as per Space News. “It’s going to deliver large mass to low Earth orbit for a long time, and it’s going to drive down costs and increase access. But if you need a moon lander, it’s going to take time.”
SpaceX responds to the former NASA administrator’s comments
In a series of posts on X, SpaceX noted that while the company is very thankful to the former NASA administrator for helping create the Artemis Program, his comments about Starship might not necessarily be coming from a place of objectivity.
SpaceX’s comments are as follows: “Like many Americans, we are thankful for Mr. Bridenstine’s service leading NASA at one point. He deserves credit for spearheading the creation of the Artemis Program. After departing NASA, he created a lobbying firm called the Artemis Group, representing a host of aerospace companies vying for NASA business.
“Mr. Bridenstine’s current campaign against Starship is either misguided or intentionally misleading. SpaceX was selected to design and develop a Human Landing System for Artemis along with Blue Origin and Dynetics during Mr. Bridenstine’s tenure as NASA Administrator.
“Starship was then selected by NASA for the Artemis III mission through fair and open competition after being identified as the best and lowest risk technical option – and the lowest price by a wide margin – by the civil servant team appointed to lead the agency’s exploration mission by Mr. Bridenstine himself.
“The decision to select Starship was confirmed repeatedly following protest and litigation from the companies not selected which delayed the start of work on the contract for many months. Mr. Bridenstine’s recent musings promoting a new landing system – going so far as to invoke the Defense Production Act – are being misreported as though they were the unbiased thoughts of a former NASA Administrator. They are not.
“To be clear, he is a paid lobbyist. He is representing his clients’ interests, and his comments should be seen for what they are – a paid lobbyist’s effort to secure billions more in government funding for his clients who are already years late and billions of dollars overbudget,” SpaceX wrote.

Elon Musk just dropped a huge detail on the Tesla Roadster
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one.”
Elon Musk dropped a huge detail on the Tesla Roadster on his latest appearance on the Joe Rogan Experience podcast.
Tesla has been teasing the Roadster for years. The company has constantly delayed the vehicle, hoping to push its limits past anything that is even imaginable by the human mind.
Earlier this year, the company said it would put on a “most epic demo” for the Roadster, displaying and unveiling all its capabilities, some new, some previously talked about. However, nobody really knows what to expect.
On the JRE Podcast, Musk joined Rogan for an over three-hour conversation about a variety of topics, but Tesla was something that was evidently on the agenda.
One of the parts of the Tesla conversation that is getting a lot of attention is Musk’s new teasing of the Roadster, saying it has “crazy technology” that might not even qualify as an automobile in the classic sense.
Musk confirmed that Tesla is “getting close to demonstrating the prototype,” and said he can guarantee the demo “will be unforgettable.”
He continued:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one.”
Musk went on to say, with a smile, that Joe would have to “wait and see” what Tesla had come up with.
He went on:
“I think it has a shot at being the most memorable product unveil ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Tesla has said for years that the Roadster would be able to at least hover, thanks to a SpaceX package that would feature cold gas thrusters that would help the vehicle get in the air.
Musk seemed very confident in his answers and very excited to show off what the Tesla Roadster is capable of. The real question is: how long will it take Tesla to get the car to market after the launch and unveiling? How many units will it manufacture? How much will it cost?
All of those things are details we will have to wait for Tesla to reveal at the Roadster event.
