What is ARRAY PROCESSOR ? Its types

ARRAY processor is  a processor that performs computations on a large array of data.
It is also called vector processor.(It execute one instruction at a time but on array of data.)
Array processor is of two types:-

1) ATTACHED ARRAY PROCESSOR
2) SIMD ARRAY PROCESSOR

Coming over attached array processor - In this an auxillary processor is attached to a general purpose computer.It enhances the performance of the host computer in specific numerical computation tasks.
* It provides vector processing for complex scientific applications.
* This attachment is done by parallel processing i.e. it contains  one or more pipelined floating point adders and multipliers.
Can be programmed by user.

The attached array processor is attached to host computer by a input-output interface or controller and The data for the attached processor are transferred from main memory to a local memory through a high speed bus.
