Enlist various kinds of addressing modes. Explain any five of same and support your answer by taking small example.
Write two address, one address and zero address instructions program for the following arithmetic expression: X = (A + B) * (C – D / E) + F * G
Assume A = + 6 and B = + 7, apply Booth algorithm for multiplying A and B. Make necessary assumptions if required.
A computer uses a memory unit with 256K words of 32 bits each. A binary instruction code is stored in one word of memory. The instruction has four parts: an indirect bit, an operation code, a register code part to specify one of 64 registers, and an address part.
In certain scientific computations it is necessary to perform the arithmetic operation (Ai + Bi) * (Ci + Di) with a stream of numbers. Specify pipeline configuration to carry out this task. List the contents of all registers in the pipeline for i=1 through 4.
Perform A – B (subtract) operation for the following numbers using signed magnitude number format. (Write necessary assumptions if required) A = + 11 and B = -
Write the difference(s) between arithmetic shift left and logical shift left instruction. Support your answer with proper illustration.
Explain any two types of mapping procedures when considering the organization of cache memory.
