Renesas RX210系列32位MCU开发方案

Renesas公司的RX210系列是高性能低电压超低功耗基于32位RX CPU核的闪存MCU,CPU具有73基本指令和9个DSP指令,最大工作频率50MHz,78DMIPS性能,乘法和除法单元能处理32x32位的运算,具有快速中断和5级流水线的CISC哈佛架构,片内调试电路,主要用在超低功耗的嵌入式应用.本文介绍了RX210系列主要特性,方框图以及Renesas入门套件(RSK)主要特性,RSK板布局图,方框图和电路图.

The RX210 Group is an MCU with the high-speed, high-performance RX CPU as its core. A variable-length instruction format has been adopted for the RX CPU. Allocating the more frequently used instructions to the shorter instruction lengths facilitates the development of efficient programs that take up less memory.

The CPU has 73 basic instructions and and nine DSP instructions, for a total of 82 instructions. It has 10 addressing modes and caters to register–register operations, register–memory operations, immediate–register operations, immediate–memory operations, memory–memory transfer, and bitwise operations. High-speed operation was realized by achieving execution in a single cycle not only for register–register operations, but also for other types of multiple instructions. The CPU includes an internal multiplier and an internal divider for high-speed multiplication and division.
