Hi All, When the Instruction/data is read from memory, it's copy will be put into the cache. Question: How does the R4k processor determines whether the value read from memory is Instruction or Data so that the value will be put into the appropriate primary cache? Thanks much, -karthi ===== The expert at anything was once a beginner ______________________________ / \ O / Karthikeyan.N \ O | Chennai, India. | `\|||/' \ Mobile: +919884104346 / (o o) \ / _ ooO (_) Ooo____________________________________ _____|_____|_____|_____|_____|_____|_____|_____|_ __|_____|_____|_____|_____|_____|_____|_____|____ _____|_____|_____|_____|_____|_____|_____|_____|_ ________________________________________________________________________ Yahoo!
