Assignment-04. A non-pipelined CPU has 12 general purpose registers (RO, R1, R2, . Following operation are supported: R12), .... ADD Ra, Rb, Rr Add Ra to Rb and store the result in Rr MUL Ra, Rb, Rr Multiply Ra to Rb and store the result in Rr MUL operations takes two dlock cycles, ADD takes one clock cycle. Calculate minimum number of clock cycles required to compute the value of the expression XY +XYZ + YZ The variables X,Y, Z are initially available in registers RO, R1 and R2 and contents of these registers must not be modified,
Suppose that you have a computer with a memory unit of 24 bits per word. In this computer, the assembly program's instruction set consists of 198 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. a. How many bits are needed for the opcode? b. How many bits are left for the address part of the instruction? c. How many additional instructions could be added to this instruction set without exceeding the assigned number of bits? Discuss and show your calculations.

A digital computer has a memory unit with 24 bits per word. The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address, similar to Marie). Each instruction is stored in one word of memory. a) How many bits are needed for the opcode? b) How many bits are left for the address part of the instruction? c) What is the maximum allowable size for memory?
Orthogonality arises when the design of an instruction set provides a "backup" instruction for each instruction that performs the same function. Please indicate whether or not it is accurate.
