CEVA Inc. has rolled a software development kit (SDK) for runtime software development based on the CEVA-XC323 DSP architecture. The CEVA-XC323 silicon embedded in the SDK delivers up to 800MHz performance. According to the company, this level of performance facilitates the design of software-based modems and associated application software for multiple communication standards, in parallel and in a real-time environment.


The CEVA-XC323 boasts up to 800MHz .

The CEVA-XC SDK enables the full implementation of physical layer (PHY) signal processing in software for various communication standards including LTE, LTE-Advanced, HSPA+, HSPA, TD-SCDMA, WiFi, DTV demodulation, digital radio and GPS.

The SDK includes the CEVA-XC323 siliconincluding CEVA's power scaling unit (PSU) that enables advanced power management within the SoC, a set of DSP software libraries and a range of standard interfaces, enabling easy integration into customer-specific system designs.

The kit also includes complete debug, profiling and tracing capabilities in real-time, to enable the modeling of real system conditions well in advance of customer silicon being available. The development kit is supported by CEVA-Toolbox, a software development, debug and optimization environment.


The CEVA-XC SDK supports various standard interfaces.

The SDK contains 6.5Gb/s optical transceiver, dual-port 1Gb/s Ethernet, 1GB of DDR2 memory, 64MB of SSRAM, HDMI in/out ports, dual Serial RapidIO transceivers, and multiple large user-programmable FPGA modules, to which can be added SoC-specific logic. The CEVA-XC323 silicon was manufactured in a 65nm process and includes the CEVA-XC323 DSP, two XC-DMA controllers, program cache (512KB of L1 data and 1MB of shared L2 memory), external 64/128bit AXI master and slave interfaces, 32bit master APB interface, multiple efficient master/slave memory interfaces, power management unit (PMU), timers, interrupt control unit (ICU), GPIOs and more.

The CEVA-XC SDK is available for purchase.
