What is computer architecture system ?

Computer architecture is a specification detailing how a set of software and hardware technology standards interact to form a computer system or platform. In short, computer architecture refers to how a computer system is designed and what technologies it is compatible with.

What is the importance of computer architecture ?

The object of architectural design is to so dividing up the functions/actions of the system as to minimize the need for communication which represents a substantial potential point of (design) failure and usually serves as a constraint on future upgrade designs.

What is Memory Reference?

These instructions refer to memory address as an operand. The other operand is always accumulator. Specifies 12-bit address, 3-bit opcode (other than 111), and 1-bit addressing mode for direct and indirect addressing.

What is Register Reference?

These instructions perform operations on registers rather than memory addresses. The IR(14 – 12) is 111 (differentiates it from memory reference) and IR(15) is 0 (differentiates it from input/output instructions). The rest 12 bits specify register operation.
