1.11 Cache Memory
Since second level cache has been embedded into the Pentium
®
II/III
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/III yields
much higher performance than external cache memories. The cache
size in the Pentium II/III CPU is either 256 KB or 512 KB. Normally,
for workstation and server applications, the 256 KB version is
suffucient. However, if your system is for heavy duty applications, the
512 KB version will help a lot. The Pentium II/III has another version
that provides much better data security if combined with DRAM ECC.
This version was specifically developed for our Pentium II/III based
SBC. Check with your vendor for various Pentium II/III models.
