Summary:
In this article, the author has described the emergence of the SIMD and MIMD architecture
for parallel processing that is used in the multiprocessor machines. I chose this article
because it provides details about parallel processing and other things, which are related to
the SIMD and MIMD architecture. In addition, the complexity of an architecture is simple in
SIMD as compared to the MIMD architecture.
In the article, the author describes how SIMD and MIMD architectures are used in parallel
processing. It can use for the distributed memory and shared memory. There are four
categories of this architecture that is based on Flynn’s taxonomy.
In addition to parallel processing and distributed memory, SIMD architecture is the best
model for every processing element. In this architecture, each processor processes its
own local memory. It has a drawback that is performance time. However, data transfer has
handled by the controlling unit.
The authors have explained the implementation architecture of SIMD, which has two
types, such as true and pipelined. In the case of MIMD, it has two types, which are shared
memory MIMD, and distributed memory MIMD architecture. Besides, scalability in size and
performance is available in SIMD but MIMD has a complex size with good performance.
There is various advantage of parallel processing.
