Introduction
This is a collection of SHA(Secure Hash Algorithm) cores. These include SHA-1, SHA-2 algorithms. In another word, these cores can perform following operations:
CoreTypeMessageDigestCyclesNotesha1.vSHA-151216081With NSA fixsha256.vSHA-25651225665sha512.vSHA-384102438497sha512.vSHA-512102451297
These cores are non-pipelined version of SHA, and have simple interfaces with the host side. Some features of the cores:
Support SHA-1(160), SHA-2(256/384/512)
Use a simple 32-bit I/O bus interface
High performance
Share hardware between different SHA processing
Can operate up to 200MHz at 0.18um Standard cell design
These cores have been verified with Shamus Software Ltds MIRACL. You can get this software library from HYPERLINK "http://indigo.ie/~mscott/" http://indigo.ie/~mscott/.
NOTE: The padding are not implemented in these cores, it is the hosts job to do the message padding.
