It's a custom implementation of an existing architecture

It's common to call the instruction set just "architecture", or ISA (instruction set architecture) to be more precise. The implementation is commonly called "microarchitecture".

RV32I doesn't define any architecture, it's just an ISA i.e. a software contract that happens to be implementable in hardware. The CPU could run on outer space goop and still be RV32I.

"RV32I doesn't define any architecture, it's just an ISA."

My friend...

		You are right, 'A' stands for Architecture. _Instruction Set_ Architecture that is. Not CPU architecture. I should have been more clear: > RV32I doesn't define the hardware architecture FTFM - satisfied?
