1.12 Cache Memory

Since the second level cache has been embedded into the Pentium® 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 memories. 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.
