Compute the effective address and the content of ACC (accumulator) for a load instruction of a 1-address machine for each type of addressing modes using the following assumptions The load instruction is of length 4 bytes, the first byte is for op ode and mode and the other two bytes contain the value 90 for an address or an immediate value ? The load instruction is stored in locations 12-15 The register (say R1)contains the value 800; The location 800...

Modify the circuit to support a MFCC
instruction.
MFCC Rd instruction: Move From Condition Codes
MFCC copies into the four rightmost bits of Rd the values of the
ALU signals Carry (C), Overflow (O), Zero (Z) and Negative (N) as
they were set by the previous R- type instruction. The remaining 28
bits of Rd are set to zero.
Describe the changes and additions needed for the
single-cycle MIPS processor datapath and control to support this
instruction.

What does the instruction jal do? It populates the PC with the address given by the input. It saves the current PC (plus 4 bytes) to the $ra register and the populates the PC with the address given by the input. It populates the PC counter with the word currently stored in the $ra register. It allocates the input number of bytes (provided as an immediate value) onto the stack. 1 points QUESTION 6 What is a function pointer?...
