Overview/Description

GreenSIDE is a cost-effective, System-on-Chip device that targets applications in wireless infrastructure equipment. The device combines two quad-MAC ST140 DSP cores, a standard ARM926-EJS RISC processor core providing a total of 29000 Mops, 7500 Mips, 4800MMacs/s, 16Mb of embedded SRAM memory, dedicated Turbo Decoding Engine (TDE) for Data error correction, and Convolutional Decoding Engine (CDE) for Voice error correction for 2.5G and 3G standards, with a complete set of high-performance peripherals. As a highly-integrated baseband modem solution, GreenSIDE offers a unique opportunity to significantly reduce the overall cost/channel and cost/MIPS.
