The full self-driving chip or FSD chip for short is [[tesla car|Tesla's]] home-grown custom designed [[autonomous driving chip]]. The chip has been in development since [[2016]] and has entered mass production in early [[2019]]. Designed as a drop-in upgrade for Tesla's existing cars, the FSD chip inherits most of the power and thermal requirements of prior solutions - including staying with the maximum power consumption of 100 W. Since the chip itself is designed specifically for Tesla's own cars and their own requirements, much of the general purpose-ability of alternative [[neural processors]] has been stripped away from the FSD chip, leaving the design with only the hardware they need. | The full self-driving chip or FSD chip for short is [[tesla car|Tesla's]] home-grown custom designed [[autonomous driving chip]].

− | At a high level, the chip is a full [[system-on-a-chip]] | + | At a high level, the chip is a full [[system-on-a-chip capable]] of booting a standard operating system. It is manufactured on Samsung's [[14-nanometer process]] at their Austin, Texas fab, packing roughly six billion transistors on a 260 millimeter squared silicon die. The FSD chip meets AEC-Q100 Grade-2 automotive quality standards. The choice to go with a mature [[14 nm]] node instead of a more [[technology node|leading-edge node]] boiled down to cost and IP readiness. There are twelve {{arch|64}} [[ARM]] cores organized as three clusters of quad-core {{armh|Cortex-A72|l=arch}} cores operating at 2.2 GHz which are used for general purpose processing. There is also relatively light GPU primarily designed for light-weight post-processing. It operates at 1 GHz, capable of up to 600 GFLOPS, supporting both [[single-precision]] and [[double-precision]] floating point operations. |
The chip features a relatively low-cost conventional memory subsystem supporting 128-bit of LPDDR4 memory operating at 2133 MHz. | The chip features a relatively low-cost conventional memory subsystem supporting 128-bit of LPDDR4 memory operating at 2133 MHz. |
