Silicon Intellectual Property (SIP) provider , Inc. has added HSPA+ software libraries for the CEVA-XC core to the company’s Software-Defined Radio (SDR) reference architecture offering. The library enables designers to implement a complete software-based multimode HSPA/HSPA+//LTE-A baseband modem solution. With many operators just beginning to rollout 4G LTE networks, backward compatibility for 3G HSPA+ and HSPA is generally a requirement for the development of 4G LTE mobile device applications. The libraries also offer forward compatibility for future systems. CEVA says that their HSPA+ software libraries support up to Release 8 of the (3GPP) HSPA+ worst-case conditions specification, including Multiple-Input Multiple-Output (MIMO) and 64 Quadrature Amplitude Modulation (QAM), with the capability for peak downlink data rates of 42 Mbps on a single CEVA-XC processor. Library features address complex receiver functions including channel estimation, equalization, de-mapping, de-interleaving, and de-rate matching.

CEVA has also formed a partnership with CellGuide to offer a software-based Global Positioning System (GPS) solution for the CEVA-XC communications processors. CellGuide is a fabless semiconductor and design services company that focuses on Global Navigation Satellite System (GNSS) solutions. Licensees of the CEVA-XC IP will now be able to leverage CellGuide’s software intellectual property to add GPS capability to their processor designs without incurring any modifications to hardware. CEVA customers will get a turnkey software-based solution, which they will be able to modify and adapt based on their particular needs. The GPS software IP has been architected by CellGuide for integration into mobile processors, with support for concurrent operation with other air interfaces in multi-mode SDR modem designs. CellGuide will be joining the CEVA-XCnet partner program, which includes a number of other SIP, (), software, and semiconductor foundry companies, including ARM, , Carbon Design Systems, Mentor Graphics, CoWare (), and TSMC.
