SuperH ST40 SH-4 core
Figure 1 illustrates the system architecture of the ST40 SH-4 core. The following section briefly
describes the features and performance of the core.
Central processing unit
The central processing unit is built around a 32-bit RISC, two-way superscalar architecture.
Operating at 166 MHz it runs with high code density using fixed length 16-bit instructions. It has a
load/store architecture, delayed branch instruction capability and an on-chip multiplier. It uses a five-
stage pipeline.
