This is an uncommon architecture which is generally used for fault tolerance.

Heterogeneous systems operate on the same data stream and must agree on the result. Examples include the Space Shuttle flight control computer [4].

MIMD Multiple autonomous processors simultaneously executing different instructions on different data. MIMD architectures include multi-core superscalar processors, and distributed systemsusing flynn s classification one shared memory space or a distributed memory space.

This is not originally part of Flynn's taxonomy but a proposed addition.

Each processing unit PU is shown for a uni-core or multi-core computer: It could mean that the machine has instructions that operate on vectors of numbers, one at a time or maybe pipelinedlike the CDC STAR The vector instructions in the CDC STAR flynn s classification pretty complex, giving flynn s classification vectors start addresses to load, a start address for storing the result vector back to memory, and an arithmetic operation.

The CDC STAR designers could have leveraged the implicit independence of the operations in the vector instructions to make some of those operations happen truly simultaneously, but they did not. It may be more appropriate to talk about whether certain instructions in an instruction set architecture are "SIMD" or not.

SAXPY in a vector unit For achieving the full performance of the vector unit all vector registers have to be filled all the time. If this feeding of the vector registers stops then the vector unit works just as a flynn s classification unit and flynn s classification the performance drops by a factor of The additional vector appearing in Fig.

This will be done automatically by the compiler to handle efficiently. From the point flynn s classification a mathematician, writing a code for a vector unit is ''only'' sequential programming without any parallelism inside. This is parallelism at the level of program execution, i.
