Compare FALCON-A eith SRC bits of MAR and MBR? Answer:- Memory Address Register (MAR) and Memory Buffer Register (MBR) are also of 16-bits while in SRC these are of 32-bits. MAR and MBR are dual port registers. At one side they are connected to internal bus and at other side to external memory in order to point to a particular address for reading or writing data from or to the memory and MBR would get the data from the memory. Difference b/w executing machine instructions with and without pipelining? Answer: We start by assuming that a given processor can be split in to five different stages as shown in the diagram below, and as explained later in this section. Each stage receives its input from the previous stage and provides its result to the next stage. It can be easily seen from the diagram that in case of a non pipelined machine there is a single instruction add r4, r2, r3 being processed at a given time, while in a pipelined machine, five different instructions are being process...
