Computer Memory Organization and Hierarchy Quiz

Cache memory is a special very-high-speed memory used to increase processing speed by storing frequently accessed data closer to the CPU.

Static RAM consists of flip-flops to store binary information and is easier to use with short Read/Write cycles, mainly used in Cache memory. Dynamic RAM stores binary information in the form of electric charge inside capacitors provided by MOS transistors, and requires a refreshing circuit to refresh the memory. It offers reduced power consumption and large storage capacity.

The Memory Management System supervises the flow of information between auxiliary memory and main memory to enable efficient data access and utilization.

Multiprogramming allows the CPU to switch between different programs, allocating CPU time to each program and enabling concurrent processing of multiple independent programs.

The purpose of the memory hierarchy is to obtain the highest possible access speed while minimizing the total cost of the memory system by organizing different types of memory with varying speeds and capacities.

The pipeline configuration for the arithmetic operation (Ai+Bi)*(Ci+Di) involves four segments: Fetch, Decode, Execute, and Write Back.

For i=1 to 6, the content of all registers in the pipeline for the given arithmetic operation can be represented as: Fetch: $A_1, B_1, C_1, D_1$Decode: $A_2, B_2, C_2, D_2$Execute: $A_3, B_3, C_3, D_3$Write Back: $A_4, B_4, C_4, D_4$

The space-time diagram for a six-segment pipeline processing eight tasks would involve segments labeled 1 to 6, with each task progressing through the segments sequentially, depicting their respective execution times.

The speedup ratio of the six-segment pipeline for 100 tasks can be calculated using the formula: $Speedup = \frac{Non-pipelined\ execution\ time},{Pipelined\ execution\ time}$Substitute the values to find the speedup ratio.
