16-Bit Digital Signal Processor Eyes Multi-Channel Assignments

Said to be the highest performance 16-bit digital signal processor (DSP) in its class, the ADSP2192 delivers 320 MIPS with up to 26 toll-quality channels of voice over network (VoN) and six channels of V.90 modem. Designed specifically for multi-channel applications, the IC features a programmable, 16-bit fixed-point architecture and is based on the 219X reusable core.
The device consists of two DSP cores for processing multiple channels and integrates 132 Kwords of on-chip RAM including 4K words of shared RAM. Each core is independent, containing a program sequencer that controls the flow of instruction execution. Any two instructions can be executed in every clock cycle.
The device also features a fully transparent instruction cache that allows simultaneous mathematical operations to be performed in every instruction cycle. Claiming to be the industry's first DSP with PCI and USB interfaces, the device can connect directly to PCI, USB and AC'97 system devices. The ADSP2192 (Model ADSP219212MKST160X) is priced at $35 each/25,000.
