Overview

DCT Engine with Camera Link Interface (DECLI) is an integrated Camera Link Interface and DCT based image compression solution. It can provide interface to any industry standard mono chrome camera (CLI) and compress data by a fixed compression ratio of 32:1 (lossy) and out put the compressed data in serial, HDLC, parallel and PCM formats.

Functionality

DECLI interfaces to the CLI compliant monochrome camera and collects the video data and further feed to the DCT engine for generating DCT coefficients. The coefficients are further filtered by the system control unit block in the FPGA for achieving the expected compression ratio. The filtered coefficients are further packed in the required format and transmitted out by the output block. The core supports transmission of compressed data in Serial, Parallel, HDLC and PCM formats.

DCT Engine with Camera Link Interface

Application

• Target destruction visualization system
• Best suited where only reduced link bandwidth is available for data transfer from the camera (especially over wireless communication)
• Surveillance of hazardous or hostile areas
• Basic design adaptable for varied re quirements

Customization

Camera interface, DCT engine and Output data formats can be customized based on requirement

Deliverables

• Firmware
• Software
• FPGA Configuration files
