    assume a machine that has instructions of length 16 bits

    GATE2014-1-9 GATE Overflow. Assume each machine has vector registers of length 64. The Multiply, Add, and Load units are pipelined and take 6, 4, and 11 cycles, respectively, to complete one operation. Memory is 16-way interleaved. In lecture, Professor Patt discussed a 2-stage pipelined machine … 4/15/2009 · Best Answer: Assuming all opcodes are the same length, you will need 8 bits to hold the operation. 2^7 is 128, which is not enough to select one of 150 operations. Since each instruction is stored in one 24-bit word, and an opcode is 8 bits, that leaves 16 bits left for the address part. Since we address 24-bit words (3 bytes) and have 16-bit addresses, we can address 3*2^16 bytes, or 192KB..

    7/17/2014 · (a) A computer has a single core processor having 16 General purpose registers and 4 additional special purpose registers. The machine has 1MB RAM. The size of each register and memory word is 32 bits each. An instruction of the machine is of fixed length and is equal to one memory words. Assume a CPU has the following instruction format: op_code mode1 operand1 [mode2 operand2] [mode3 operand3] Instructions use 1-3 operands. Each operand has its own mode specifier. The CPU’s instruction set has 61 operations (op codes) and there are 6 different addressing modes available. Assume a fixed length 32-bit instruction.
