QUESTION 4 (a) Central Processing Unit (CPU) contains the Arithmetic Logic Unit (ALU), control unit and registers. Figure Q4(b) illustrates the internal structure of a CPU. (b) Arithmetic and logic unit Status flags Shifter Complementer Arithmetic and Boolean logic Internal CPU bus Registers Control unit Control paths Figure Q4(a): Internal structure of a CPU (i) Explain the process that occurs between the elements in the CPU. [C2, SP1] [8 marks] (ii) Analyze the design issues that exist for register organization in the CPU. [C4, SP3] [8 marks] Discuss the differences between instruction-level parallelism and machine parallelism? [C4, SP4] [5 marks] (c) Symmetric multiprocessors (SMP) include two or more identical processors. All processors share a single main memory and access to the input/output devices which are controlled by a single operating system. Based on this statement, discuss the effect of multi-programming and multi-processing on the performance of SMP. 104 DALA
