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.
