Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

MISD runs on device arrays that are arranged in a systolic fashion. A systolic array is a "wavefront" or data processing pipeline. As the data is what really initiates execution, these subparts may function independently of the rest of the programme. When the clocks of the Processors in a systolic array are synchronised, they may do calculations "lock-step."
DMA transfers 8 bits in one CPU cycle at regular intervals. For a 2 Mhz processor, if CPU uses 0.4% processor cycles for DMA, determine the data transfer rate in bits per second.
A systolic array is an example of a device that employs MISD. The systolic array is a pipeline of networked nodes for data processing. No programme counter is necessary because execution is triggered by the receipt of fresh data. The components of a timed systolic array operate in "lock-step," with each component performing computation and communication in a single clock cycle.
A MISD device is a systolic array. Systolic arrays are wavelike data processing node networks. These segments don't require a programme counter since fresh data starts execution. In a timed systolic array, all nodes compute and transmit "in lock-step."
