what are the features of microprocessor ?, Basic Computer Science

Previously two sections the fundamentals of the workings and architecture of the central processing unit has been explained. There has been a common look at easy processor architecture, a clarification of the technique by which instructions are executed, and how the range of different addressing modes anxiety how the CPU processes instructions. Though, modern CPUs are very hardly ever as easy as the ones that have been discussed thus far.
While the information covered up to this position is still applicable and applicable to the majority of microprocessors, many refinements to the workings and architecture have also been implemented.
• Pipelining
This is a technique by which the processor can be occupied in the execution of more than a single instruction at once. Justifiably, this enables the execution of the program to be finished with greater speed, but is not without complications and problems. These have to be defeat by careful design.
• CISC and RISC architectures
In excess of the course of the development of the modern day processor, two competing architectures have appeared. CISC and RISC have more than a few major differences in features and ideas, but both were designed with the intention of improving CPU performance. At Present processors tend not to be severely adhering to either architecture, in its place being a mix of the two ideals.
• Modern architectures
Exterior of pipelining, RISC and CISC, many other improvements to the common architecture of the microprocessor have been developed. These are in many differing areas for example cache memory and specialized instruction set extensions. New advancements are added with every new production of processors.
