Santa Clara, Calif.--March 25, 1998--Quantum Effect Design, Inc.(QED) announced that General Instrument Corp. (GI) has chosenQED's RM5230 MIPS RISC microprocessor for their DCT-5000+ advancedinteractive digital cable platform. The DCT-5000+ is GI's next-generationdigital set-top terminal that will support the Multimedia Cable NetworkingSystems ("MCNS") protocol to facilitate high-speed data networkingapplications, such as Internet access or cable IP telephony.
GI has completed definitive agreements to supply 12 leading North Americancable system operators, serving over 46 million subscribers, with at least15 million Opencable-compliant advanced digital set-top terminals.
The powerful DCT-5000+ platform features a built in MCNS cable modem with a triple tuner architecture, which will enable customers to simultaneouslywatch TV and surf the Internet or watch and talk using cable IP telephonyfunctionality. The DCT-5000+ also has PC-like features, such as optionalbuilt-in hard drive for local storage and advanced graphics processing,permitting 3-D rendering and animation capabilities for high-end applications.
The QED RM5230 is a 64-bit MIPS microprocessor with a32-bit system bus interface designed to provide workstation-class performance at an affordable price for consumer applications. Its superscalar instruction issue architecture significantly increases processor efficiency andperformance. The RM5230 is the low-cost derivative of the QED-designedR5000, currently used in Silicon Graphics workstations, EFI Fiery printers, and Midway arcade games. Featuring the same MIPS IV-compatible double-precision floating point unit (FPU) as the R5000, theRM5230 supports standard IEEE-754 floating point operations and performs350 MFLOPS single-precision performance at 175-MHz operation.
The RM52xx family features a superscalar instruction issue architecture.It also implements a DSP-enhanced MIPS IV instruction set architecture that includes the "Multiply-Add" (Muladd) and "three-operand multiply" instructions.
The RM5230 is a superscalar 64-bit microprocessor with a 32-bitmemory interface that provides 233 Dhrystone 2.1 MIPS performance at175 MHz. Key features include superscalar instruction issue, 5-V tolerant I/Os, 16-kbyte instruction cache, 16-kbyte data cache (both 2-way set associative, with per set locking), full-featured MMU, low system cost, 32-bit memory interface, and IEEE 1149.1-compliant JTAG boundary scan functionality.
QED's 32-bit RM5230 is currently available in versions from 100 MHz to175 MHz. The RM5230 is currently available in a 128-pinpackage and is the lowest-priced member of QED's RM52xx family at under$20 in quantities of 10,000.
