ADSP-2171 General Description
The ADSP-2171, ADSP-2172, and ADSP-2173 are single-chip microcomputers optimized for digital signal processing (DSP) and other high-speed numeric processing applications. The ADSP-2171 and ADSP-2172 are designed for 5.0 V applications. The ADSP-2173 is designed for 3.3 V applications. The ADSP-2172 also has 8K words (24-bit) of program ROM.
The ADSP-217x combines the ADSP-2100 base architecture (three computational units, data address generators, and a program sequencer) with two serial ports, a host interface port, a programmable timer, extensive interrupt capabilities, and onchip program and data memory.
In addition, the ADSP-217x supports new instructions, which include bit manipulationsbit set, bit clear, bit toggle, bit testnew ALU constants, new multiplication instruction (x squared), biased rounding, and global interrupt masking, for increased flexibility. The ADSP-217x also has a Bus Grant Hang Logic (BGH) feature.
The ADSP-217x provides 2K words (24-bit) of program RAM and 2K words (16-bit) of data memory. The ADSP-2172 provides an additional 8K words (24-bit) of program ROM. Powerdown circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-217x is available in 128-pin TQFP and 128-pin PQFP packages.
Fabricated in a high-speed, double metal, low power, CMOS process, the ADSP-217X operates with a 30 ns instruction cycle time. Every instruction can execute in a single processor cycle. The ADSP-217x's flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. In one processor cycle the ADSP-217x 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
This takes place while the processor continues to:
• receive and transmit data through the two serial ports
• receive and/or transmit data through the host interface port
• decrement timer
