Cache memory
Since the second level cache has been embedded into the Pen-
tium® II CPU, you do not have to take care of either SRAM chips
or SRAM modules. The built-in second level cache in the Pentium
II yields much higher performance than the external cache memo-
ries. The cache size in the Pentium II CPU is either 256 KB or 512
KB. Normally, for workstation and server application, the 256 KB
version is enough. However, if your system is for heavy duty
applications, the 512 KB version will help a lot. Specifically for our
Pentium II based SBC, the Pentium II has another version that
provides much better data security if combined with the DRAM
ECC. Check with your vendor for various Pentium II models.
