Texas Instruments recently announced that it licenses Ethernet for Control Automation Technology (EtherCAT®) for its ARM®- and DSP+ARM-based embedded processors. It will be featured in the upcoming Sitara™ ARM microprocessors (MPUs) planned for the beginning of the fourth quarter of 2011 and in the C6-Integra™ DSP+ARM processors beginning in 2012.
This system-on-chip, based on TI’s silicon technology, integrates the EtherCAT slave controller, enabling you to tightly couple the application processor for high throughput, low latency access, board space savings and lower total costs. Plus, the programmable real-time unit (PRU) can more easily adapt as industrial standards evolve over time.
The EtherCAT Protocol meets the real-time performance and flexibility functions that are critical for the embedded ARM-based devices. EtherCAT allows master and slave controllers to communicate with each other without a host computer in high-noise industrial environments. The TI approach to EtherCAT with the programmable real-time unit (PRU) on the Sitara ARM MPUs and C6-Integra DSP + ARM processors allows for flexible implementation that can more easily adapt as industrial standards evolve over time.
