I took a quick look at the summary datasheet for the AVR32 and it made me wonder what exactly the AVR32 is? Atmel have been using ARM IP for some time now and there are lots of ARM like blocks (AHB matrixes and APB Bridges) that look very familiar. The 16KB I and D caches are also found on ARM processors.
Atmel already have the IP for the ARM920T as used in their AT91RM9200 MCU.
I'm woindering whether the AVR32 is something completely new or whether it is a tweaked ARM core with some extra hardware for DSP functions and a revised interrupt controller and instruction pipeline? The Intel XScale processors started out as ARM processors didn't they?
