Hardware & Software Design for Video Capture, Processing, Display
We provide the "glue" that connects the video components inside a video camera, image processor, LCD display. Our typical design has a FPGA and a microprocessor. The micro-processor can be a "soft" processor inside the FPGA or an external processor. The FPGA code is written in Verilog or VHDL, and the microprocessor code is C or C++. Three recent projects are shown below:
Low-cost endoscope board with video, CPU, and touch screen GUI
X-Ray camera with electronic image rotation
Radar video scan converter PC/104-Plus card with graphics overlay
We have written low-level drivers for WindRiver's VxWorks and embedded Linux. We can also supply a simple foreground processing loop with background interrupt service routines, instead of an RTOS. Our designs usually need FDA or FAA approval, so fewer lines of source code means less testing and easier DO-254 and DO-178 approval. We have written our own graphics and image processing libraries, so only the code that is really needed is included in the application. We believe that simple is better in design, implementation and especially quality control.
Past designs have included a printer decompression engine, sonar processor, radiometric camera, radar display, in-flight entertainment display, x-ray camera, and endoscope color video processor. Supported video formats include DV, SD-SDI, HD-SDI, DVI, HDMI, 1080i, 1080p, NTSC and PAL Y/C, CVBS. Video processing modules include format conversion, scaling, noise filters, high dynamic range, motion-adaptive de-interlace, and smooth image rotation at 1/4 degree increments.
Our company philosophy:
Making it simple is harder than making it complicated, but simple is always better
Real engineering is providing the same capabilities with a simple low cost design
