Hardware Questions

In case of Move A to B it will move whatever the value of A into B.It mean it will move numeric, alphanumeric and alphabatic value.

In case of COMPUTE B=A it will assign the value of A into B. But in case of compute only numeric value will be compute.

Cache momory is a small high-speed memory. it is used for temporary storage of data & information between the main memory and the CPU(center processing unit). The cache memory is only in RAM.

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. AS the microprocessor processes data, it looks in the cache memory and if it finds the data there.

You can divide the frequency of a clock by just implementing T Flip flop.

Give clock as clock input and tie the T input to logic 1.

Execution Unit receives program instruction codes and data from BIU, executes these instructions and store the result in general registers.

Program counter holds the address of either the first byte of the next instruction to be fetched for exectuion or the address of the next byte of a multi byte instruction, which has not beeb completely fetched. in both the cases it gets increnented automatically one by one as the instruction bytes get fetched. Also Program register keeps the address of the next instruction.

interrupt is a signal send by external device to the processor so as to request the processor to perform a particular work.

A signal informing a program that an events has occurred. when a program receives an interrupt signal, it takes a specified action (which can be to ignore the signal).

Latch is a D-type flip-flop used as a temporary tsorage device controlled by a tiing singnal, which can store 0 or 1. the primary function of a Latch is data storage. It is used in output devices such as LED, to hold the data for display.

To Store Monitor programs.
