A student  is asked to use scientific notation to perform the following operations:

In order to design a circuit that takes three bits (x2, x1, x0) as input and produces one output bit (0), the following K-map truth table is built to produce 1 as an output (0) if and only if x2x1x0 representing a 3-bit two’s complement is positive. Select the most simplified sum-of-product form for the output (0).

Suppose a 32bit MIPS CPU has the following on-chip datacache; number of set: 256 set associativity: 256 line (block) size: 16 bytes write policy : write allocate and write back   How many bits  are needed for this on-chip datacache?
