Pipelining is a technique used in processor design to increase the number of instructions that can be executed simultaneously. It involves breaking down the execution of an instruction into multiple stages, each of which can be handled by a separate part of the processor. The design of the instr...
The Arithmetic Logic Unit (ALU) is primarily responsible for these operations. Result Storage: After processing the instruction, the CPU stores the results either in memory or in specific registers. The Program Counter (PC) is updated to point to the next instruction’s address. The CPU then ...
How does pipelining in processors relate to the concept of an accumulator? Pipelining is a technique used in processors to increase instruction throughput. The accumulator can be one of the pipeline stages, storing intermediate results between stages to facilitate concurrent execution of multiple instruct...
Since most floating-point calculations have rounding error anyway, does it matter if the basic arithmetic operations introduce a little bit more rounding error than necessary? That question is a main theme throughout this section. The section Guard Digits discusses guard digits, a means of reducing...
What is ALU (Arithmetic Logic Unit) with explanation of input device, output device, memory, CPU, motherboard, computer network, virus, software, hardware etc.
The earlier processors had only one arithmetic and logic unit in its CPU. Furthermore, the ALU could only perform one function at a time, so that the process for executing a long sequence of arithmetic and logic instruction is quite slow. But nowadays the processors are available with multiple...
ALU (arithmetic logic unit) - performs mathematical, logical, and decision operations. CU (control unit) - directs all the processors operations.Over the history of computer processors, the speed (clock speed) and capabilities of the processor have dramatically improved. For example, the first ...
On the other hand, a micro-architecture is the implementation of the ISA in a particular design. It deals with concepts like pipelining, execution order of instructions, branching, etc. It should be noted that Processors with the same instruction set can have different microarchitectures. Here RD...
