Explain cache structure in Pentium.
Cache structure in Pentium: The cache in the Pentium has been changed by the one determined in the 80486 microprocessor. The Pentium has two 8K-byte cache memories in place of one as in the 80486. Here is an 8K-byte data cache and an 8Kbyte instruction cache. The instruction cache stores merely instructions, whereas the data cache stores data used with instructions.
