1.11 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 worksta-
tion 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.
