difference between simd and spmd in parallel computing
SPMD In SPMD, multiple autonomous processors simultaneously execute the same program at independent points, rather than in the lockstep that SIMD imposes on different data. With SPMD, tasks can be executed on general purpose CPUs; SIMD requires vector processors to manipulate data streams. Note that the two are not mutually exclusive.
MIPS architecture MIPS (an acronym for Microprocessor without Interlocked Pipeline Stages) is a reduced instruction set computer (RISC) instruction set architecture (ISA)[1]:A-1[2]:19 developed by MIPS Technologies (formerly MIPS Computer Systems). The early MIPS architectures were 32-bit, with 64-bit versions added later. There are multiple versions of MIPS: including MIPS I, II, III, IV, and V; as well as five releases of MIPS32/64 (for 32- and 64-bit implementations, respectively). As of April 2017, the current version is MIPS32/64 Release 6.[3][4] MIPS32/64 primarily differs from MIPS Iâ€“V by defining the privileged kernel mode System Control Coprocessor in addition to the user mode architecture.
