-
A few details
-
The IO File is accessed during stages s5 or/and s6.
As presented here, the IO File can do more than byte-oriented read-write operations. It can also do bit processing.
The following data is provided to the IOF, for each pipeline stage in which IOF access is required:
- byte address
- bit address
- opcode
- byte data in
-
Accessing the IOF
-
Main pipeline registers that implement IOF accessing instructions are presented here:
