It’s a parallel computing architecture type in which multiple functional units work on the same data at the same time. Pipeline topologies fall under this category, though purists could argue that the data after every stage in the pipeline is different.
In this article, we will dive deeper into MISD Computer Architecture according to the GATE Syllabus for (Computer Science Engineering) CSE. Keep reading ahead to learn more.

What is MISD?
MISD is an abbreviation for Multiple Instruction and Single Data stream. Because no real system has been built using the MISD structure, it is primarily of theoretical importance. Multiple processing units work on a single data stream in MISD. Each processing unit works on the data in its own way, using its own instruction stream.

Here, M = Memory Modules, P = Processor Units, and CU = Control Unit
Example
The experimental Carnegie-Mellon computer C.mmp (in 1971)
