Computer architecture as \"The structure of a computer that a machine language programmer must understand to write a correct program for a machine\". Computer architecture can be classified into four main categories. These categories are defined under the Flynn's Taxonomy. Computer architecture is classified by the number of instructions that are running in parallel and how its data is managed. True SIMD architectures can be determined by its usage of distributed memory and shared memory. Both true SIMD architectures possess similar implementation as seen on Fig.4, but differ on placement of processor and memory modules.
