STMicroelectronics Adds DSP to Reconfigurable-Processor SoC for Wireless Infrastructure Applications
Single-chip solution shows versatile combination of high-speed RISC and DSP programmable cores with peripherals and reconfigurable interfaces to add flexibility and reduce costs
GENEVA, June 6 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM), a leading developer of system-on-chip (SoC) solutions, has today disclosed details of an enhanced version of its recently announced STW21000, a multi- purpose microcontroller that targets applications in wireless infrastructure equipment. Fabricated using ST's 130nm CMOS technology, the new device, dubbed the STW22000, adds a 600MHz 16/32-bit dual-MAC DSP core to the existing device, which already integrated an exceptionally rich mix of technologies including a 300MHz ARM926EJ-S RISC core, 16 Mbits of embedded DRAM, an eFPGA (embedded Field-Programmable Gate Array) block, reconfigurable interfaces, and a wide range of analog and digital peripherals such as A/D and D/A converters.
The STW22000 is the latest advanced System-on-Chip (SoC) product to be announced from ST's Wireless Infrastructure Division and, like the other members of the product family, it was defined in co-operation with several leading wireless infrastructure manufacturers.
The additional ST122 DSP core combines VLIW and RISC features to achieve the optimum balance between performance and size. Also embedding a dedicated CDE (Convolutional Decoder Engine) the STW22000 is a low-cost alternative for baseband signal processing in 2G cellular modems and other signal-processing applications.
"The addition of an embedded DSP and associated coprocessor adds a whole new dimension to what the product can do," said Marc Goddard, Director of ST's Wireless Infrastructure Business Unit. "In real application terms, the new STW22000 will be used for baseband signal processing in 2G and 2.5G cellular modems and other signal processing-based applications.
Software development on the programmable logic is supported by an advanced and integrated software tool chain that encompasses traditional leading FPGA tool providers which enables the programming, debug, and validation of the reconfigurable interfaces within a unique design environment. The ARM Real View(TM), or any independent third-party software tool chain, can be used for the software development on the CPU core.
ST also provides a complete set of development tools for the embedded DSP core, to evaluate the performance, and to develop, debug, and integrate Application Code on the chip via an ARM/DSP environment, providing multi-Core Development/Debug capabilities.
The STW22000 is delivered with a Board Support Package (BSP) to support multiple Operating System (OS) implementations, and many application software elements are already available due to the use of ST's standard ST122 DSP core. The STW22000 is available now with a price range of $30 in volume.
