IPO HIPOTHETIC COMPUTER
The IPO has 8 instructions and each is identified by its Operation Code.
The Operation Code “ïnforms” to CPU which action should be performed.
Each instruction has its own structure and size and occupies in IPO memory, from 1 to 11 bytes.
In computer science, an instruction set architecture (ISA) is an abstract model of a computer.
It is also referred to as architecture or computer architecture. A realization of an ISA, such as a central processing unit (CPU), is called an implementation.
In general, an ISA defines the supported data types, the registers, the hardware support for managing main memory, fundamental features (such as the memory consistency, addressing modes, virtual memory), and the input/output model of a family of implementations of the ISA.
