Description Computer architecture A computer that does not have the ability for parallel processing. SIMD The processor has several ALUS. Each ALU executes the same instructions but MISD on different data. There are several processors. Each processor executes different instructions drawn from a common pool. Each processor operates on different data drawn from a common pool. SISD There is only one processor executing one set of instructions on a single set of data. MIMD
