Overview
Not all encryption requirements demand gigabit performance, 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.....but with plenty of emphasis
placed on the lower end of the spectrum too. This way you can choose the most
optimal fit for your particular requirement. In this section we look at the
Tiny AES core family.
Helion Tiny AES Solutions
The Helion Tiny AES core is our smallest solution, and was designed specifically
for applications where data rates are low but minimal area is absolutely paramount.
This requirement applies to many applications, for example set-top boxes, mobile
wireless communications systems or satcomms. The result is the smallest fully
featured AES solution available today spanning all ASIC and FPGA technologies.
Despite its extremely small footprint, the Tiny AES core is a very capable performer.
It 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 (take a look at our AES modes pages
for more information). The table below outlines the kind of area and performance
achievable using the Tiny AES core.
