Suppose we have a five-stage pipeline (fetch, decode/read reg, ALU, memory, write result).  What dependencies and/or hazards exist in the following sequence of instructions? Assume the first operand is the destination and there is a unified L1 cache. List them in the form g-h, j-k … List every dependency and/or hazard, even if it does not result in a pipeline bubble. a add r5,r6,r7 b ld r9,18(r5) c add r8,r6,r9 d or r3,r7,r5 e andi r6,r5,15 f br_pos r5,r9

Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:
