WebComparison of SIMD and MIMD • SIMD computers require less hardware than MIMD computers because they have only one control unit. • SIMD computers require less memory because only one copy of the program needs to be stored. In contrast, MIMD computers store the program and operating system at each processor. WebPEn PE2 PE1 Control Unit Figure 5: SIMD Organisation 3) Multiple Instruction and Single Data stream (MISD) In this organization, multiple processing elements are organised under the control of multiple control units. Each control unit is handling one instruction stream and processed through its corresponding processing element.
