MISD

Micheal J. Flynn introduced the idea of an MISD (Multiple Instruction, Single Data) computer architectures in his original taxonomy in 1966.[1]

Dr. Yan Solihin defines MISD as "..an architecture in which multiple processing elements execute from different instruction streams, and data is passed from one processing element to the next."[2] He also notes that MISD architectures are restricted to certain types of computations due to the requirement of data-passing between processing elements.[2] Each processing element executes different instructions on the data stream.[3] Every time the data is processed by a processing element, we can always argu that the data is no longer the original data introduced at the start of the stream.[4]


MISD Computers

It is widely believed that no actual MISD computer exists in practice.
