ADSP-2192:  16-bit Fixed-Point DSP For Multichannel Applications

Product Description

Dual-Core 320 MIPS Performance with PCI and USB Interface

The ADSP-2192 is a dual-core 16-bit fixed-point DSP optimized for multichannel voice/data and other high-speed numeric processing applications. It is the first product available based on ADI's new high performance ADSP-219x digital signal processor (DSP) core capable of 320 million instructions per second (MIPS). Future products on the ADSP-219x roadmap will follow two paths, one addressing high-performance requirements delivering up to 1200 MIPS and another addressing low power requirements needing less than 0.1 mW/MIPS.

It is the first product available based on ADI's new high-performance ADSP-219x digital signal processor (DSP) core capable of 320 million instructions per second (MIPS).

Building off its full code-compatibility with the entire ADSP-218x DSP family, the DSP cores used in the ADSP-2192 utilize the ADSP-2100 family base architecture consisting of three computational units, data address generators, and a program sequencer. The ADSP-2192 will also support a wide range of interfaces including: Peripheral Component Interconnect (PCI) with CardBus and Sub-ISA interface mode for embedded applications and Universal Serial Bus (USB) with interface to serial EPROM devices, AC'97 and DMA. Other ADSP-2192 highlights include a programmable timer for each core, extensive interrupt capabilities along with on-chip program and data memory.

With 132K words of on-chip memory, the ADSP-2192's first core processor (P0) is configured with 64K x 16-bit Data Memory, 16K x 24-bit Program Memory, and Boot ROM. The second core processor (P1) is configured with 32K x 16-bit Data Memory, 16K x 24-bit Program Memory, and Boot ROM. The ADSP-2192 also features 4K x 16-bit words of shared memory that will reduce external data accesses allowing a higher sustained processor performance.

Power-down circuitry is provided to meet the low-power needs of battery-operated portable equipment. The ADSP-2192 is available in a 144-pin LQFP package.

Fabricated in a high-speed, low-power, CMOS process, the ADSP-2192 operates with a 6.25-ns instruction cycle time (160MHz/320MIPS). The ADSP-2192's dual-core architecture and comprehensive instruction set enable the processors to perform multiple operations in parallel, and any two instructions can execute in a single DSP processor cycle.
