ARM’s IoT expansion plans are continuing apace, with the announcement of the Cortex-A76AE CPU design. The new chip brings the Split-Lock processor redundancy feature to the 64-bit Cortex-A7 architecture, more commonly found in ARM’s smaller 32-bit MCUs that are used in mission-critical systems. The goal is to make ARM’s designs an option for those looking at CPU choices for self-driving systems in vehicles. While a sound decision, it’s too early to estimate the impact on the market. ARM has a solid reputation for such safety-critical silicon, and given its stature in the mobile world, there’s a lot of cross-pollination and channel opportunities for the company to build on. In terms of roadmap, ARM expects the new CPU to appear in…
