Santa Clara, Calif.--July 20--QED, Inc. (Santa Clara) announced the RM52x1 MIPS RISC microprocessor family. The new QED product family includes the RM5231, RM5261 and RM5271. In just over a year, QED has doubled the system performance of the RM52xx family of processors.
The RM52x1 family is targeted at high-performance embedded applicationssuch as Internet terminals, advanced set-top boxes, network routers/switches/hubs, communications devices, xDSL MODEMS, Windows-based terminals, "thin" servers, automobile navigation systems, printers, and games.
The RM52x1 family features a maximum of 345 Dhrystone 2.1 MIPS 266 MHz64-bit MIPS RISC CPU with a high-performance 125 MHz memory interface capableof 1000 MBytes per second peak transfer rates. The family also uses a superscalar instruction issue architecture that increases processor efficiency for both the CPU and overall system performance. This architecture enables one integer and one floating point instruction to be processed within one microprocessor clock cycle, thereby achieving higher system performance without increasing clock speed. In addition it has 32 Kbyte instruction and 32 Kbyte data caches.
The RM52x1 family uses the MIPS IV Instruction Set Architecture (ISA) with DSP instruction (multiply-add, 3-operand multiply) extensions to enhance signal processing, e.g. soft-MODEM or other commonly used DSP algorithms. The MIPS IV ISA is a superset of the MIPS I-III ISA now currently sold by manyvendors.
The RM5231 is the 32-bit memory interface version of the family. TheRM5261 is the 64-bit memory interface version, and the RM5271 has a 64-bit memory interface with an integrated, on-chip secondary cache controller.
The RM5231, RM5261 and RM5271 products are available now, with production volumes scheduled for Q498. The RM5231 is available up to 250 MHz in a 128-pin Power-Quad package with prices starting at $26 in 10,000-piece quantities. The RM5261 is available up to 266 MHz in a 208-pin Power-Quad package with prices starting at $45 in 10,000-piece quantities. The RM5271 is available up to 266MHz in a 304-pin SBGA package with prices starting at $54 in10,000-piece quantities.
