The CEVA-XC323 which is the fifth generation of the widely deployed CEVA-XC architecture is optimized for IoT communication applications as well as cellular UE and wireless and wireline terminals. The CEVA-XC323 delivers powerful vector capabilities alongside a general computation engine to supply the performance and flexibility demanded by a wide variety of IoT communication applications.

Based around a fully programmable DSP processor architecture, the CEVA-XC323 offers a wealth of features including two vector processing units. Each unit provides a powerful SIMD engine that allows for 8 simultaneous VLIW instructions. The processing units give efficient DSP support for non-vector data as well as control and ANSI-C operations.

Extremely powerful computation capabilities include 32 16×16 bit MAC operations with 64-bit arithmetic operations, or more than 200 16-bit operations, per cycle.

The integrated solution offers a complete memory subsystem with Tightly Coupled Memories (TCM), caches, AXI and APB interfaces and an advanced DMA controller thus ensuring easy integration and optimal performance in target SoCs.

Exceptional power efficiency is provided by the embedded Power Scaling Unit (PSU 2.0) the power optimized Tightly Coupled Extensions (TCE) and an enhanced power optimized pipeline.
