What is the use of ready pin?

What is the use of ready pin?

Ready: This is an active high input control signal. It is used by microprocessor to detect whether a peripheral has completed (or is Ready for) the data transfer or not. The main function of this pin is to synchronize slower peripheral to faster microprocessor.

Which pin is used to change the mode of the 8086 processor?

There are two modes of the 8086 microprocessor. The pin 33 decides whether the processor will work in minimum mode or maximum mode.

When test pin is microprocessor enters into wait state?

If the TEST pin goes LOW (logic 0), execution will continue (WAIT instruction functions as a NOP), else if TEST pin goes HIGH (logic 1) the processor remains in an idle state. ✵ READY : If the READY pin goes LOW (logic 0) the processor enters into wait state and remains in an idle state.

What is single cycle MIPS?

a single cycle cpu executes each instruction in one cycle. in other words, one cycle is needed to execute any instruction. in other words, our cpi is 1. each cycle requires some constant amount of time.

Is MIPS a single cycle?

Two versions of the single-cycle processor implementation for MIPS are given in Patterson and Hennessey.

What is the difference between single cycle and multi-cycle?

another important difference between the single-cycle design and the multi-cycle design is the cycle time. in the single cycle processor, the cycle time was determined by the slowest instruction. in the multi-cycle design, the cycle time is determined by the slowest functional unit [memory, registers, alu].

What is single clock cycle?

1. A clock cycle is a single period of an oscillating clock signal. Clock speed, rate, and frequency are used to describe the same thing: the number of clock cycles per second, measured in Hertz (Hz).

Is a shorter clock cycle better or worse why?

A CPU with higher clock speed is generally better if all other factors are equal, but a mixture of clock speed, how many instructions the CPU can process per cycle (also known as instructions per clock cycle/clock, or IPC for short) and the number of cores the CPU has all help determine overall performance.

What is faster RAM or ROM?

RAM is faster than ROM just because writing data to a ROM chip is a slow process, whereas writing data to a RAM chip is a faster process. A RAM chip can store multiple gigabytes (GB) of data, up to 16 GB or more per chip; A ROM chip typically stores only several megabytes (MB) of data, up to 4 MB or more per chip.
