Hints on the Multicore CPU Design for Personal Computers

Abstract

Abstract - Multi-core processors are created by combining multiple units, each called the core, containing the processing unit, registers and a cache. This study provides a detailed analysis on the performances of multicore CPUs for personal computers. We parallelized some cryptographic algorithms with OpenMP tool and tested one 2-core and one 4-core CPU with two cryptographic software one of which imposes high data load and the other one high work load. In the light of the experiments that stress the CPUs from these two different aspects, we present our hints and suggestions for designing multicore chips for the usage in personal computers.
