ARC EM22FS safety processor
The DesignWare® ARC® EM22FS Safety Processor simplifies development of safety-critical applications and accelerates ISO 26262 certification of automotive system-on-chips (SoCs). The ASIL D compliant EM22FS processor is a preverified dual-core lockstep implementation including a self-checking safety monitor. There is also an option to run the cores in an independent dual core mode for ASIL B or non-automotive applications requiring higher performance based on the same design. A tightly coupled architecture is supported such that the interrupt controller, MPU, watchdog timer, and options such as uDMA and FPU are instantiated within the main and shadow core for full redundancy. The ARC EM22FS processor is supported by comprehensive safety documentation including FMEDA reports and the ARC MetaWare Toolkit for Safety with ASIL D Ready certified compiler to generate ISO 26262 compliant code.
