Tokachi-4A Technology Demonstrator

This advanced state-retention power-gating demonstrator, code-name “Tokachi-4A”, contains a Cortex-M0 system control processor and a dual-core Cortex-A5 application processor subsystem, again designed as a collaboration with Arm Ltd on TSMC 65nm Low-Power process technology available.

Tokachi-4A was taped out in October 2012 and working and in characterization at the end of January 2013, and the silicon includes an alternative implementation of the IP watermarking research circuitry.
