For D latch: always@(enable) q<=d;

For D flip flop: always@(opsedge clock) q<=d; 

One difference is while using the include page directive, in translation time it is creating two servelts. But, while using the include action tag, in translation time it is creating only one servlet.

INPLEMENTATION:

For SUM, The two inputs A and B are given to XOR gate.

For Carry, The two inputs A and B are given to AND gate.

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

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).

Immediate, Direct, Register, Register indirect, Implied addressing modes.

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.

As W and Z alphabets are not widely used similarly as W and Z is internally used they would have been named so
