Overview

The XC21 is the most efficient vector DSP core available today for communications applications.

The XC21 DSP is designed for low-power, cost- and size-optimized cellular IoT modems, NTN VSAT terminals, eMBB and uRLLC applications. Ceva-XC21 offers scalable architecture and dual thread design with support for AI, addressing growing demand for smarter, yet more cost and power efficient cellular devices

Targeted for 5G and 5G-Advanced workloads, the XC21 has multiple products configurations enabling system designers to optimize the size and cost to their specific application needs.

The Solution

The Ceva-XC21, based on the advanced Ceva-XC20 architecture, features a product line of 3 vector DSP cores. Each of the cores offers a unique performance & area configuration with a SW compatibility between them. The different cores span across single thread or dual thread configurations, and 32 or 64 16bits x 16bits MACs.

The Ceva-XC212, the highest performing variant of the Ceva-XC21 delivers up to 1.8x times the performance of Ceva’s previous-generation Ceva-XC4500 architecture, while reducing the core area.

Ceva-XC210, the smallest configuration of the Ceva-XC21, enables system designers to reduce the core die size in 48% compared with the previous generation.

Ceva-XC211 offers the same performance envelope compared with the previous generation at 63% of the area.
