Gidel’s real-time JPEG image compression (encoder) IP, gil_jpeg_encode, enables high-performance JPEG compression on FPGA. The compression IP is unique in its fast processing capacity, low latency, and compact silicon utilization. As a result of its compactness, the IP can be implemented on a small FPGA device to compress high-performance camera image streams, or, alternatively, the IP can be instantiated multiple times on a single larger FPGA device. The IP includes a host interface and an API suite for software control.
The JPEG IP’s input stream is in YCbCr format with an optional converter from RGB, monochrome, etc. The degree of compression can be adusted allowing selectable tradeoff between storage size and image quality. The specifications table shows a compression performance example using 4:2:2 encoding at 540 MPixels/s and at 1.84 GPixels/s. The latency for this example is 130 µS.

Gidel’s Supporting Eco-System
The Gidel eco-system includes infrastructure and development tools enabling to quickly develop a high-end custom FPGA frame grabber with real-time compression and image processing capabilities. The eco-system includes:
- FPGA Frame Grabber and Image Processing Systems
Gidel offers FPGA-based systems with open reconfigurable acquisition flow allowing the user to customize the grabbing and to add user image processing blocks including the compression IP. The frame grabber boards interface with the host computer via PCIe or alternatively may operate as a standalone system.
- Multi-Camera Acquisition System
The Gidel InfiniVision is a unique image acquisition system designed for grabbing from multi-cameras/sensors. Combined with real-time compression as much as 100 camera video streams can be supported simultaneously.
- Highly Efficient Video Recording & Playback Systems
Based on real-time compression, Gidel offers a recording system that is exceptionally efficient in both its offloading throughput and compactness of required memory resources. This capability has significant benefits for applications with demanding bandwidth and/or memory resources, e.g., field applications. Based on Gidel’s CamSim a playback sub-system, images can then be retrieved at the original throughput for a variety of application tasks.
- Proc Developer’s Kit
The Proc Developer’s tools enable to map the FPGA board to the desired data flow and interfaces. The following figure demonstrates one possible implementation using InfiniVision, compression and custom image processing.
- Gidel Customization Services
Based on 25 year experience, Gidel offers customization services for developing tailored Vision/Imaging systems incorporating compression according to the customer’s specifications. Gidel takes advantage of its uniquely flexible and powerful infrastructure to quickly implement the target application within impressive short time spans.
