CoCubes Computer Architecture Question and Answers Quiz-1

MAR can interact with secondary storage in order to fetch data from it.

The processor BUS is used to connect the various parts in order to provide a direct connection to the CPU.

The Operational and processing part of the CPU are collectively called as data path.

The processor operating is much faster than that of the I/O devices , so by using the status flags the processor need not wait till the I/O operation is done. It can continue with its work until the status flag is set.

In this method the processor constantly checks the status flags , and when it finds that the flag is set it performs the appropriate operation.

This is a method of accessing the I/O devices which gives the complete power to the devices, enabling them to intimate the processor when they’re ready for transfer.

The stalls are a type of hazards that affect a pipe-lined system.

This time also retards the performance speed of the processor.

The Tomasulo algorithm is a hardware algorithm developed in 1967 by Robert Tomasulo from IBM. It allows sequential instructions that would normally be stalled due to certain dependencies to execute non-sequentially (out-of-order execution).
