Published

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.

xAI supercomputer faces pushback from Memphis politicians

Local leaders in Memphis warn Elon Musk’s xAI hub could pollute local communities, despite Tesla Megapacks now stabilizing power.

xAI’s supercomputer in Memphis faces pushback from local leaders and environmental groups over concerns about air pollution despite its promise of economic growth.

xAI’s Memphis facility was touted as the world’s largest supercomputer. It has sparked opposition from the NAACP, Sierra Club, and Mississippi Democratic Party Chairman Cheikh Taylor.

State Rep. Taylor spoke at a Southaven church press conference recently, arguing that the xAI facility in Memphis, Tennessee, would disproportionately harm black residents in north Mississippi.

“In the State of Mississippi, the goal is to separate Republicans and Democrats on race alone. So, if you’re a Democrat in this state, you probably look like me,” Taylor said.

He also criticized prioritizing economic gains over environmental health, asking, “Can you trust Elon Musk to tell the truth?”

Tennessee State Rep. Justin J. Pearson echoed these concerns, linking the opposition to a broader fight against pollution. “The paltry money xAI has dangled in front of our short-sighted leaders is not worth the cost of breathing dirty and–in some cases–deadly air,” Pearson said.

These local leaders and environmental groups are urging local governments and the Environmental Protection Agency to deny xAI’s air permit applications for 45 to 90 methane gas turbines in the Memphis and Southaven areas.

xAI has not directly addressed the criticism but has taken steps to power its Colossus supercomputer sustainably. Last month, the Greater Memphis Chamber announced that Tesla Megapack batteries would stabilize the facility’s power, with a new 150-megawatt electric substation completing its first construction phase.

“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months,” shared the Chamber.

An additional 160+ Megapacks were delivered to xAI’s Memphis facility for the Colossus 2 data center within the same month.

Announced in June 2024, the xAI facility was hailed by Greater Memphis Chamber CEO Ted Townsend as the largest capital investment by a new-to-market company in Memphis history. Despite its economic promise, environmental concerns continue to fuel opposition, highlighting tensions between technological innovation and community health in the Deep South’s emerging AI hub.
