Here's some nice quotes to spark some interest:
IDT’s World Class MIPS RISC Family
The R4640 was designed by QED, Inc. under contract to IDT as part of IDT’s high-performance RISC microprocessor family. IDT’s product offering delivers a wide range of software-compatible price/performance choices based on the MIPS instruction set, including twelve 32-bit RISControllers ™ and the complete family of 64-bit Orion microprocessors. IDT has optimized the designs of its high-performance microprocessors for use in a range of embedded applications including internetworking, multimedia, data communications and telecommunications products. Superior price/perfor-mance,low power consumption and small form factor have made the MIPS RISC family of microprocessors the emerging standard for a number of digital consumer products, including the Sony Playstation ™ , Nintendo’s Ultra-64 ™ video game
set and Echostar’s digital broadcast satellite receiver.
The new WebTV Plus Receiver and WebTV Plus Network Service announced by WebTV Net-works today brings entertaining new experiences and information to consumers through the integra-tion of television programming and the internet. New platform features supported by the R4640 include hard disk drive and printer control, real-time video decoding (MPEG, Quicktime®) and real-time
audio decoding (MPEG, AC-3, RealAudio®). All decoding operations enabled by the IDT R4640 processor are compliant with emerging multimedia standards — MPEG, QuickTime, AC-3, RealAudio — and are achieved by the processor’s integrated DSP and floating point operation capa-bilities.
