Boost MCU security AND performance with hardware accelerated crypto

In this Product How-To article, TI’s Carlos Betancourt and Greg Turner describe how the hardware accelerated cryptography modules built in to the company’s ARM-based Sitara processor family can be used to accelerate compute-intensive cryptographic algorithms and offload those tasks from the ARM core which can then devote the additional headroom to performance of real-time deterministic control functions. In 2010, …
