DIOPSIS® (ARM + DSP)
Why Diopsis?
Because Atmel's Diopsis® 940HF is the combination of the high performance ARM926EJ-S™ microcontroller and the 1 GFLOPs, 40 bit floating point Magic DSP™. This integration, together with a rich set of peripherals, provides a powerful yet convenient solution for many different markets, including professional and in-car audio, acoustic signal processing, speech/speaker recognition, robotics and many others.

System overview
Diopsis parallel architecture incorporates a VLIW floating point processor, Magic DSP, delivering up to 10 floating point operations per cycle and an ARM926EJ-S ARM® Thumb® RISC CPU. The rich set of peripherals and internal memory provide a highly flexible system solution. The system-on-chip embeds distributed DMA to support data moves related to the on chip peripherals and to the processing performed by mAgic. The availability of on-chip memory for Magic and ARM reduces the data traffic on the external bus and allows an effective usage of the available processing and I/O resources.
