OTBN code snippet collection

This directory contains some code snippets that give examples of how to do various tasks in OTBN code.

  • modexp.s: An example of how to do modular exponentiation.
  • pseudo-ops.s: An example of the pseudo-operations supported by the OTBN ISA.
  • mul256.s: An example of a 256x256 bit multiply using the MULQACC instruction.
  • mul384.s: An example of a 384x384 bit multiply using the MULQACC instruction.
  • barrett384.s: An example of a modular multiplication kernel based on Barrett reduction.

Also included in this directory is a Makefile fragment that can be used to assemble and link the snippets. This can be used standalone or included in another Makefile.
