Unformatted text preview: m ultiple i nstruction stream, m ultiple d ata stream) these are multiprocessor systems each processor can execute a different program on its own data hence, multiple instruction streams (programs) and multiple data streams Both SIMD and MIMD are parallel processing architectures since the processors execute operations in parallel. They are, by default, multiprocessor architectures, which can be subdivided into two categories. 1. Global memory architectures common, global memory is shared by all processors 2. Local memory architectures one local memory per processor may also have a global memory Global memory MIMD architectures are also known as tightly-coupled multiprocessor systems ; local memory MIMD systems are known as loosely-coupled multiprocessor systems ....
