Product Details

The ADSP-2181 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.

The ADSP-2181 combines the ADSP-2100 family base architecture(three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, extensive interrupt capabilities, and on-chip program and data memory.

The ADSP-2181 integrates 80K bytes of on-chip memory configured as 16K words (24-bit) of program RAM, and 16K words (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-2181 is available in 128-pin TQFP and 128- pin PQFP packages.

In addition, the ADSP-2181 supports new instructions, which include bit manipulations-bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking for increased flexibility. Fabricated in a high speed, double metal, low power, CMOS process, the ADSP-2181 operates with a 30 ns instruction cycle time. Every instruction can execute in a single processor cycle. The ADSP-2181's flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. In one processor cycle the ADSP-2181 can:

  • Generate the next program address
  • Fetch the next instruction
  • Perform one or two data moves
  • Update one or two data address pointers
  • Perform a computational operation

218X-EMULATOR Circuit Diagram

Product Details

The EZ-ICE® serial emulator system provides state-of-the-art emulation for the ADSP-218x family of processors by providing a controlled environment for observing, debugging, and testing activities in a target system. The EZ-ICE connects directly to the target processor through the emulation interface port. Its ease of use, full speed emulation and shielded board will ensure your design process runs smooth.

 

The debugger available for ADSP-218x EZ-ICE is Analog Devices' VisualDSP++ development environment. All software is sold separately.
