Overview
The Helion Fast Hashing cores provide the ultimate in performance by implementing
each of the hashing algorithms using one clock per algorithm round whilst using only
moderate logic area. These cores support data throughputs up to 4 Gbps and can be used
to perform plain cryptographic hashing for digital signatures and integrity checking,
or Keyed HMAC for data authentication. They optionally support hash state unload and
reload which allows efficient hashing of fragmented or packetised messages.
The Fast Hashing core is also available in versions which support certain combinations of
hash algorithms in the form of multi-mode cores. Here common functionality is shared
wherever possible to provide the most efficient high performance cores supporting different
combinations of the SHA-1, SHA-2 family, and MD5 hashing algorithms. These cores are ideal
for use in high throughput applications requiring support for multiple algorithms on a
message by message basis, or in the case of the versions with state unload/reload on a
block by block basis.
These high performance cores are available in versions for use in ASIC as well as Xilinx,
Altera, Lattice and Actel FPGA. In common with all Helion IP cores they have been designed with
each technology firmly in mind to yield the very best and most efficient results. For more
detailed information on these cores, please download the appropriate datasheet below.
