 The CEVA-X family of cores is based on a unique mix of Very Long Instruction Word (VLIW) and Single Instruction Multiple Data (SIMD) architectures. The VLIW architecture allows a high level of concurrent instructions processing, thereby providing extended parallelism and low power consumption. The SIMD architecture allows single instructions to operate on multiple data elements, thereby resulting in code size reduction and increased performance. This processor family offers best-in-class performance, scalability, ease of programmability at the C level, and the flexibility to support a wide variety of applications. The CEVA-X family offers an architectural framework from which multiple DSP designs are derived. Each DSP design is aimed to serve different application needs characterized by performance, power consumption, and cost.
CEVA-X1641: High performance CEVA-X processor targeting more-demanding DSP applications. The quad-MAC, 8-way VLIW CEVA-X1641 DSP core offers the performance required for demanding DSP applications.

The CEVA-X1641 is a high-performance, low-power, fully synthesizable DSP with a 16-bit data width and quad 16-bit fixed-point MAC units.
The CEVA-X1641 is based on a unique mix of Very Long Instruction Word (VLIW) and Single Instruction Multiple Data (SIMD) architectures. The VLIW architecture allows a high level of concurrent instructions processing, thereby providing extended parallelism, as well as low power consumption. The SIMD architecture allows single instructions to operate on multiple data elements resulting in code size reduction and increased performance.
In addition to DSP operations, the CEVA-X1641 provides strong support for control code, thereby reducing cycle count and program size associated with control and overhead code:
The data memory subsystem is configurable and supports up to 1MB L1 data space. Using a separate AHB-Lite system bus and a programmable DMA, this can be extended up to 4GB in L2. Similarly, the program memory subsystem is configurable and supports up to 1MB L1 program space, TCM and cache. Using a separate AHB-Lite system bus and a programmable DMA, these can be extended up to 4GB in L2.
