Nios II Custom Instruction User Guide
Custom instruction logic can perform various tasks such as storing intermediate
results or reading memory to control the custom instruction operation. The conduit
interface also provides a dedicated path for data to flow into or out of the processor.
For example, custom instruction logic with an external interface can feed data directly
from the processor’s register file to an external first-in first-out (FIFO) memory buffer.
