addressable memory

What is meant by addressable memory capacity? What is meant by directly addressable memory capacity?

Compute the size of the program counter and the instruction register.

A 32-bit microprocessor has 32-bit instructions with 2 fields, 1st field: 1 byte, contains the opcode 2nd field: operand or operand address How many bits are needed for the program counter and the instruction register?

Data transfer rate

32-bit microprossor 16 bit external data bus driven by an 8 MHz input clock bus cycle: minimum duration equals 4 input clock cycles What is the maximum data transfer rate across the bus that this microprocessor can sustain in bytes?

Addressable Memory

32 bit computer 32 bit instruction: 2 fields:opcode field and immediate operand or operand address opcode = 1 byte wide express ans in powers of 2 1.give number of available unique instructions 2.give max indrectly addressable mem capacity in bytes. 3.give max directly addressable memory capacity in bytes. 4 give bits needed for the program counter and instruction register. 5 max value of an unsigned data operand. Please show how you got the answers.

Determine, which cache block will the memory reference 111Bh map to in the given memory organisation.

Suppose, a computer has 2^16 bytes of main memory. There is a direct-mapped cache of 1KB with a line size of 4 bytes. Determine which cache block will the memory reference 111Bh map to?
