Claimed to be the industry's most efficient multi-core DSP devices for basestation PHY and MAC, the OCT2224W is part of Octasic's latest family of multi-core DSPs. It delivers three times more power efficiency than any other DSP on the market today, according to the company and the best performance-to-power ratio in the industry. Designed for small cell and femtocell-based applications, the DSPs are based on the second generation of the company's asynchronous Opus DSP architecture (or Opus2). The DSP performs LTE PHY and MAC for a 20MHz 2x2 BTS at an unprecedented 3W. Using the integrated design environment, Opus Studio, the DSP is programmable and includes 24 Opus2 DSPs Cores. This homogeneous architecture simplifies application partitioning and allows coarse grain parallelism. The programmable hardware accelerators support today's cellular standards and can support revisions. In addition to I/O interfaces an ARM core is available. The devices can be used for low-power basestations for rural areas, macro basestations, outdoor small-cell basestations, and indoor high-traffic and enterprise femtocells. PHY software libraries offer standard compliant GSM, EDGE, WCDMA, HSPA+, and LTE functionality. The DSP core processes up to 64 HSPA+ or LTE users on a single device and has up to three native radio interfaces. There is Serial Rapid IO, Gigabit Ethernet, USB, PCIe, NAND, TDM support.
