ACC Code Snippets

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

• modexp.s: An example of how to do modular exponentiation.
• pseudo-ops.s: An example of the pseudo-operations supported by the ACC 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.
• calc_montgomery_consts.s: An example of calculating the Montgomery constants.

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.
