The CEVA-X is CEVA’s sixth-generation DSP processor core family, following in the footsteps of predecessors such as CEVA-Oak and CEVA-Teak. The CEVA-X family, which made its debut in 2002, is highly scalable and includes variants with two, four, and eight multipliers. Members of the CEVA-X family target a wide range of signal-processing applications, from personal communications to home entertainment.

This report provides an independent analysis and evaluation of the digital signal processing capabilities of the first two members of the CEVA-X family to be introduced, the two-MAC CEVA-X1620 and the four-MAC CEVA-X1640. The report examines the key features of these cores, including data path, execution units, memory architecture, and programming model.

The signal processing performance of the CEVA-X1620 and CEVA-X1640 is evaluated using a suite of digital signal processing benchmarks developed by BDTI. The report includes benchmark execution times, energy consumption, and memory usage results for the CEVA-X1620 and CEVA-X1640 and competitors. Execution times combine cycle count results with the clock speed for the processor; energy consumption combines execution time and processor power consumption.

The complete set of CEVA-X1620 and CEVA-X1640 benchmark results is included in an appendix in both tabular and graphical format and is presented alongside the results for several other processors to illustrate relative performance on digital signal processing algorithm kernels.

This report is intended for anyone interested in understanding the signal processing performance and capabilities of the CEVA-X1620 and CEVA-X1640 processor cores. This report is especially useful for electronic system designers, hardware and software engineers, SoC designers, engineering managers, and product marketing managers. It will aid in assessing the suitability of the CEVA-X1620 and CEVA-X1640 cores for specific applications and will allow designers to make informed decisions when considering these cores for their latest designs.
