Huawei made early advances in this area with the NPU in the Kirin 970. The authors describe the advantages of a software-hardware co-design approach and then summarize the benefits it brings to its Occula neural processing unit (NPU):Understanding the ARM Cortex-M MPU.
Many processors in the Cortex-M family come equipped with a memory protection unit. That can be quite handy in many cases, not just as a safety or security measure in production but also during development. An MPU exception can be a great hint when you are debugging memory access problems.The first is powered by a Rockchip RV1109 system-on-chip with a 1.5GHz dual-core Arm Cortex-A7 CPU and 400MHz RISC-V coprocessor, a 2D-capable graphics processor, a vision processing unit (VPU) offering H.264/H.265 encode at up to 2,688x1,520 plus 1,280x720 at 30 frames per second from each camera module, and a neural processing unit (NPU) with.
