- Embedded board doing hard realtime IO signals (100us response time) and Ethernet/IP communication on a 8bit CPU with 4KB RAM
- Windows device driver for a special PCIe card receiving continuous 80MB/s data from an image sensor into system RAM.
- soft real-time image sensor processing the stream data with latency below 3ms: interpolate dead pixels, normalize gain, apply 2d band stop filter
- soft real-time image post-processing on 60MB/s stream, with latency below 20ms: illuminated area & motion detection, spatial and temporal noise reduction, multi-resolution non-linear detail enhancement processing, adjust contrast & brightness
Above processing must run on a desktop quad-core with max 40% CPU load.
It required manual threading and hand-written vector code (SSE intrinsics) to reach the performance.
