PCI Audio/Modem ICs Come In Two Flavors

Jan. 1, 1999

Offered in digital signal processing (DSP) or in host signal processing (HSP) versions, the V.90 SuperLink products meet the requirements of next-generation PCs with respect to high-performance audio and 56-kbps data, fax and voice communication. The HSP-based chips (see photo) incorporate a digital audio accelerator, an audio codec, and a modem codec. The DSP-based chips include a high-performance DSP to off-load the host CPU and increase overall system performance.Both chipsets feature 500-MIPS equivalent processor performance to accelerate multi-stream PC audio and 64-channel Wave Processor for DirectSound and/or wavetable applications. At the heart of both chipsets is the firm's Maestro-2EM digital audio accelerator.
