An Embedded Low Power/Cost 16-Bit Data/Instruction Microprocessor Compatible with ARM7 Software Tools

摘要

A 16-bit THUMB instruction set microprocessor is proposed for low cost/power in short-precision computing. It achieves 40% gate count, 51% power consumption and 160% clock frequency comparing to ARM7, even the performance is 67% better in narrow width memory at the same clock frequency. The ARM7 software is also compatible.
