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
IIyields 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.
