7001AS–DPS–03/04

Description

DIOPSIS 740 is a Dual CPU Processor integrating a mAgic DSP and an ARM7TDMI™

RISC MCU, plus a total of 245 Kbytes SRAM. The system combines the flexibility of the

ARM7TDMI RISC controller with the very high performance of the DSP.

mAgic is a high performance VLIW DSP delivering 1 Giga floating-point operations per

second (GFLOPS) at a clock rate of 100 MHz. It has 512 data registers, 16 address reg-

isters, 10 independent operating units and 2 independent address generation units. For

instance, activating all the computing units, it can produce one complete FFT butterfly

per cycle. mAgic operates on 32-bit fixed-point and IEEE 754 40-bit extended precision

floating-point numeric format. It has also on-chip 17K x 40-bit data memory locations

and 8K x 128-bit program memory locations. Efficient usage of the internal program

memory is achieved through a code compression mechanism.

An optimizing assembler frees the user from the burden of dealing with the parallelism

of the processor resources and drastically simplifies the code development.

The ARM7TDMI™ embedded micro controller core is a member of the Advanced RISC

Machines (ARM

performance and very low power consumption. The ARM architecture is based on

Reduced Instruction Set Computer (RISC) principles, and the instruction set and the

related decode mechanism are much simpler than those of micro programmed Complex

Instruction Set Computers.

This simplicity results in a high instruction throughput and impressive real-time interrupt

response. The ARM7TDMI™ supports 16-bit Thumb® subset of the most commonly

used 32-bit instructions. These are expanded at run time with no degradation of system

performance. This gives 16-bit code density (saving memory area and cost) coupled

with 32-bit processor performance.

A rich set of peripheral and a 32 Kbytes internal memory provide a highly flexible and

integrated system solution.
