computer architecture

Exercise 1: Fill in the gap: Program counter (PC), Cache memory (CM), Instruction cycle (IC), Multicore Processor (MC), Arithmetic and Logic Unit (ALU). 1etc. 2- ................ : is an electronic chip consisting of at least two processors. This kind of devices is responsible for parallel computing and computer performance amelioration. 3- ................ : is a memory implemented inside the CPU chip. It has three levels: level 1 and 2 are implemented within each core, and level 3 is implemented outside of cores. its role is important in accelerating program execution. 4: is a register responsible for storing the address of the next instruction to be fetched. In case of branching, Its content is transferred into a stack and replaced by the address of the new location. 5defines the successive steps to accomplish the execution of one instruction. It is composed of fetching, decoding, execution and storing phases
