Describe how concepts such as RISC, pipelining, cache memory, and virtual memory have evolved over the past twenty-five years to - Research Paper Example

observed during the evolution of computing was, that with the implementation of new and advance techniques to address old problems the room of improvement in the performance of the computing systems remained persistent. The new solutions in turn produced new problems and this cycle goes on. For example to address the problem of incompatibility between the sizes of physical memory and program code, the concept of virtual memory and the techniques of paging and demand paging were introduced. These in turn resulted in multiple problems like, Access latency due to the involvement of secondary storage. Memory allocation for oversized page tables for which different strategies like multi level paging, inverted page tables and hashed page tables were applied (These have their drawbacks too). The involvement of cache as TLB to reduce access latency. Frame allocation and page replacement strategies and their drawbacks. Thrashing etc. The improvement capacity always coexisted with the upcoming solutions and increasing requirements. The last few decades saw the advent of some remarkable achievements like the RISC architecture, pipelining, cache, super scalar processing, memory management systems and virtual memory. The computational power increased manifolds as a result of these achievements. Referring to “Reduced instruction set computing” The type of computer architecture that involved simple instructions that were comprehensive and lesser in number. RISC incorporated registers along with the main memory itself for the
