HDCP Encryption-Decryption Engine

The Trilinear Technologies High-bandwidth Digital Content Protection (HDCP) Encryption Decryption Engine IP core implements the HDCP 1.3/2.3 digital stream cipher for both encryption and decryption operations. When used in combination with the Trilinear HDCP Authentication Software Stack running on a local processor, this IP core provides a complete, real-time solution for HDCP 1.x or HDCP 2.x protection of a digital link.

Data in

Streaming interface using parallel data format for processing multiple symbols per clock cycle.

Data out

Low-latency streaming interface that parallels the input interface, providing consistent latency in both encrypted and plain text modes.

Host

32-bit AMBA Peripheral Bus (APB) 4 interface for configuration information and control.
