Hi there, I am researching the purchase of a 386 box and I need to know
about the different types of cache available.  I have heard of "direct
mapped"(maps one 32k chunk of memory) and 2 way set associative (splits
the 32k into 2 16k chunks).  Are there more?

The machine will be used for signal processing (audio).  The data is probably
no going to be within 32k of the code(sometimes it will but there will 
definately be times that it won't).  Is the 2-way type cache what I want?
will it matter?  Am I missing something?

Send mail and I will summarize
