AT572D740

  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.AT572D740 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. AT572D740 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 AT572D740 embedded micro controller core is a member of the Advanced RISC Machines (ARM®) family of general purpose 32-bit microprocessors, which offer high 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 AT572D740 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.
