GENERAL DESCRIPTION

 The ADSP-2184 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications. 

 The ADSP-2184 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-2184 integrates 20K bytes of on-chip memory configured as 4K words (24-bit) of program RAM and 4K 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-2184 is available in 100-lead LQFP package.

  In addition, the ADSP-2184 supports instructions that include bit manipulations—bit set, bit clear, bit toggle, bit test— ALU constants, 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-2184 operates with a 25 ns instruction cycle time. Every instruction can execute in a single processor cycle.
