MOUNTAIN VIEW, Calif., March 29 /PRNewswire-FirstCall/ -- MIPS Technologies, Inc. (Nasdaq: MIPS) today announced that the embedded industry's highest-performance, lowest power, 32-bit synthesizable processor cores with integrated DSP functionality have been released for general availability and licensing. The award-winning MIPS32(R) 24KE(TM) core family enables OEMs and semiconductor companies to significantly reduce SoC costs, die area, and power consumption. Early access licensees have already received silicon and announced products based on the 24KE core family. One of the first announced products based on this core family is the INCA(R)-IP2 SoC developed by Infineon Technologies AG (FSE/NYSE: IFX) for the VoIP market which contains two 24KE cores. (See Infineon's release entitled "Infineon's Unique VoIP Processor Revolutionizes IP-Phone Designs, Doubling CPU Performance for Feature Rich Devices with Benchmark Voice Quality," March 2, 2006, at

With its converged RISC/DSP functionality, the 24KE core family offers an ideal solution for companies competing in cost-sensitive and power-sensitive consumer electronics markets, where many applications require both control and signal processing. Traditionally, many SoCs use a RISC CPU for control functions and a separate DSP for signal processing. By integrating the MIPS(R) DSP ASE (Application-Specific Extension), the 24KE core family eliminates the need for a separate DSP.

Among the benefits of the 24KE cores are lower silicon cost, lower power consumption, and an easier, shorter, less-costly development process. In addition, the 24KE core family delivers up to 3x the signal processing performance of RISC processors without the DSP ASE.

Versatile, Synthesizable Processor

One of the distinguishing features of the 24KE core family is its unprecedented versatility. It is fully static, fully synthesizable, and requires no custom cells or memories. It can be synthesized using best-of-class physical IP from multiple vendors. For example, in a 90nm GT process, using high speed memories from Dolphin Technology and high speed standard cells, the 24KE cores can achieve a clock frequency of 850MHz. At 1.46 DMIPS/MHz, this design provides an impressive 1240 DMIPS.

For SoCs where maximum speed is not the only goal, the 24KE cores can be synthesized in a low-cost 90nm G process using high density standard cells and memories such as those from Virage Logic. Using this IP, when optimized for power and area, a complete 24KE processor, including 16K I and D Level 1 caches, occupies just 2.0mm(squared) and consumes only 0.43mW/MHz. Even lower power figures can be achieved by using more aggressive low-power techniques such as multi-VT and voltage/frequency scaling.
