Cortex-M0+ Simplifies 32-Bit MCUs

摘要

No caches. No FPU. A pipeline with only two stages. An instruction set composed almost entirely of 16-bit instructions. Are we in the disco days of the 1970s? Nope, it's 2012, and ARM is introducing a new 32-bit CPU core that plumbs the depths of simplicity and low power consumption. Even by RISC standards, a 32-bit design can't get much simpler than this.
