1.2
The SH-DSP is a 32-bit microcontroller based on the Renesas SuperH RISC engine (abbreviated
below as “SuperH”) and incorporating the signal processing performance of a general-use digital
signal processor (DSP). The SuperH already supported some DSP type instructions, such as
multiply and accumulate. In the SH-DSP, the DSP functions have been enhanced, and full DSP
data bus have been implemented. The SH-DSP is backward compatible at the object code level
with the SH-1 and SH-2 CPUs.
The SuperH only has 16-bit instructions. The SH-DSP basically has the same 16-bit instructions,
but it also has additional 32-bit DSP instructions that it uses for parallel processing of DSP type
instructions. The SuperH uses a standard Neumann architecture, but the SH-DSP has the DSP data
bus of the expanded Harvard architecture.
Table 1.2 lists the added features of the SH-DSP.
