4.4.1
The instruction cache of the SH7750 or SH7750S is of the direct-mapping type and consists of
256 cache lines, each composed of a 19-bit tag, V bit, and 32-byte data (16 instructions). The
SH7750R's instruction cache is 2-way set associative. Each way consists of 256 cache lines.
Figure 4.6 shows the configuration of the instruction cache for the SH7750 and SH7750S.
Figure 4.7 shows the configuration of the instruction cache for the SH7750R.
