Overview
Many requirements for AES encryption fall in the middle ground in terms of
the throughput they demand, and Helion recognise that in order for IP to be
an effective choice, it should never be a compromise. Where many IP vendors
may limit you to a choice of one or two solutions, Helion are different.
We have developed a range of four AES core families each offering a different
speed/area balance which together cover any throughput requirement up to many
tens of Gbps; this way you can choose the most optimal fit for your particular
requirement. Furthermore, we have invested a great deal of effort into
developing our mid-rate solutions to a point where they are supremely efficient
and very easy to use. In this section we look at the Standard AES core family.
Helion Standard AES Solutions
The Helion Standard AES core family is our mid-rate solution, aimed at applications which
require a few hundred Mbps throughput, whilst offering a really efficient area footprint.
This core is perfect for many applications, for example wired and wireless networking,
or encrypting audio or video streams. The result is a core with a particularly high
speed-to-area ratio, spanning all ASIC and FPGA technologies.
Despite its compact footprint, the Standard AES family forms a very powerful
and flexible platform. It has been designed in modular form and is supplied as a series
of powerful, re-usable building blocks. This way, you can build up all kinds of
interesting solutions where resources can be shared or replicated according to your
exact requirements. The Standard family offers full AES encryption and decryption
using any combination of the three AES key sizes (128-, 192-, and 256-bits).
It can be used to implement any of the common block cipher modes as well as many of
the more recent complex modes (take a look at our AES modes
pages for more information). The table below outlines the kind of area and
performance achievable using the Standard AES core.
