Standard AES cores


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.

If the performance of the Helion Standard AES core does not match your needs, try looking at our Fast AES cores if you need to go faster, or our Tiny AES cores if you are able to run at a lower rate.
