Guys I want to understand these terminologies correctely. I want to get correction if my understanding of these terms is flawed.
ISA = this is the machine language code 0's and 1's generated by a compiler. These opcodes are visible to the programmer of a particular processor.
Micro-code = This is the code present in the ROM of the control Unit. It is used for executing the same ISA opcode codes, in different ways for different microarchitectures. eg:- microcode for a pipelined adder is different than for a koggestone adder in a processor.
Microarchitecture = This is the hardware implimentation for implementing the given ISA. Micro-architectures vary from one processor to another, but all processors operate on the same ISA.
Micro-code and Micro architecure are interrelated. For a given micro-architecture there is a given microcode.
This is my understanding of ISA, Micro-code and micro-architecture.
ISA is a standard
the other 2 are implementation specific. Please correct me if my understanding is flawed.
Thanks
