Introduction
The SH-1 and SH-2 incorporates a RISC (Reduced Instruction Set Computer) type CPU. A basic
instruction can be executed in one clock cycle, realizing high performance operation. A built-in
multiplier can execute multiplication and addition as quickly as DSP.

The SH-DSP is a 32 bit microcontroller based on Renesas SuperH
RISC engine that realizes the
same signal processing capability as a general usage DSP (Digital Signal Processor). The SH-DSP
offers an improvement on the DSP functions of multiplication and multiply and accumulate in
SuperH microprocessors by using a DSP style data path function. It maintains upward
compatibility at the object code level with the SH-1 and SH-2 microprocessors and has the many
functions, low power usage, and low price of other SuperH microprocessors.
The SH-DSP achieves high performance in processing operations by using a RISC CPU core and
a DSP unit with DSP functions. This new type of single chip RISC-DSP simultaneously integrates
the peripheral functions needed to build systems into the SH-DSP and provides the lower-power
consumption vital to microprocessor applications.
This Software Manual describes in detail the basic architecture and instructions for the SH-1, SH2,
and SH-DSP and is intended as a reference on instruction operation and architecture. It also covers
the operation of pipelines, which are a feature of the SuperH microprocessor.
