Low-cost parallel processing is required for autonomous vehiclesUltra high-performance CPU is tend to be catched attention, indeed, CPU of ECU that individually controls the brake and the power train must also change significantly.
If the driver changes from a human to a machine, the ECU is also required to respond in units of sub-second to micro-second. For that purpose, the CPU of the ECU can not make it in time without parallel processing.
MIPS core is hardware multi-threaded processingSpeaking of parallel processing, CPU multi-core is common, however, in automotive ECU, it is difficult to demonstrate their performance and cost performance is also bad because automotive ECU is very chatty.
Multithreading that performs parallel processing with one CPU core is suitable. Especially Imagination Technologies' MIPS CPU core is high-speed because switching threads by hardware.
Does low-cost parallel processing become a trend of automotive SoC?
