Atmel Diopsis 940HF User Manual

Atmel's Diopsis® 940HF is designed for data-intensive applications requiring the combination of a high

performance microcontroller unit and floating point DSP capablities. Its 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 ARM926EJ-S supports the Jazelle® technology for Java

®

acceleration. A rich set of peripherals and internal memory provide a highly flexible and integrated 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.

1. Full Peripheral Set.

2. Some peripherals are not accessible by the user in this low-cost version. Reduced Peripheral Set = Full Peripheral Set - 2 CANs - 3 SSCs - 1 SPI - 1 TWI

- 2 USARTs. Consequently the related PIO lines can be used only as SW controlled PIO lines (not linked to any peripherals).
