The ADSP-2185M is a single-chip microcomputer optimized for digital signal processing (DSP) and other high-speed numeric processing applications.
The ADSP-2185M 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-2185M 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-2185M is available in a 100-lead LQFP package and 144 Ball Mini-BGA. In addition, the ADSP-2185M supports new instructions, which include bit manipulations-bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (* squared), biased rounding, result-free ALU operations, I/O memory transfers, and global interrupt masking, for increased flexibility. Fabricated in a high-speed, low-power, CMOS process, the ADSP-2185M operates with a 13.3 ns instruction cycle time. Every instruction can execute in a single processor cycle. The ADSP-2185M's flexible architecture and comprehensive instruction set allow the processor to perform multiple operations in parallel. In one processor cycle, the ADSP-2185M 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 internal DMA port
• Receive and/or transmit data through the byte DMA port
• Decrement
