Preface
The SH-4 has been developed as the top-end model in the SuperH™* RISC engine family,
featuring a 128-bit graphic engine for multimedia applications and 360 MIPS performance.
The SH-4 CPU has a RISC type instruction set, and features upward-compatibility at the
instruction set level with SH-1, SH-2, SH-3 microcomputers.
In addition to single- and double-precision floating-point operation capability, the on-chip FPU
has a 128-bit graphic engine that enables 32-bit floating-point data to be processed 128 bits at a
time. It also supports 4 × 4 array operations and inner product operations.
A superscalar architecture is employed that enables simultaneous execution of two instructions
(including FPU instructions), providing performance of up to twice that of conventional
architectures at the same frequency.
This software manual gives details of the SH-4 instructions. For hardware details, refer to the
relevant hardware manual.
