Overview
The Helion Tiny Hashing core family provides the lowest area, lowest power hashing solutions available
for use in ASIC as well as Xilinx, Altera, Actel and Lattice FPGA families. The cores have been highly
optimised in each target technology by utilising the most efficient logic and memory resources available
to provide a family of low footprint hashing cores.
The Tiny Hashing cores are ideal for use in low data rate, low area and low power applications
where hardware acceleration of hashing algorithms is a requirement. They are intended for applications
requiring hashing for digital signatures or keyed HMAC (FIPS 198) for data authentication and integrity
checking in lower data rate designs than the Helion Fast Hash core family. They are provided as standard
with support for full state unload and reload to allow efficient hashing of multiple fragmented or
packet-based message streams.
In particular, the cores provide a very small silicon footprint hashing solution for situations where
one or more hash algorithms must be implemented; be that an IPsec solution where keyed HMAC using multiple
hash algorithms is required to provide data authentication and integrity for packets exchanged over IPsec
connections; or an application that must perform both SHA-256 and SHA-384 calculations for NSA Suite B
Digital Signatures.

The table above shows resource and data throughput figures for the Tiny Hash core version implementing
the most commonly used SHA-1 and SHA-256 hash algorithms without HMAC support. Please see the datasheets
below for resource and throughput figures for other popular versions of the core in your target technology.
If the performance of the Tiny Hashing core family does not match your system requirements, try looking
at our Fast Hashing core family for higher throughput capabilities.
