- portable network graphics — (file format) /ping/ (PNG) An extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-colour, greyscale and truecolour images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. PNG is designed for on-line viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. PNG is robust, providing both full file integrity checking and simple detection of common transmission errors. Also, PNG can store gamma correction and chromaticity data for improved colour matching on heterogeneous platforms.
- rate monotonic scheduling — (algorithm) A means of scheduling the time allocated to periodic hard-deadline real-time users of a resource. The users are assigned priorities such that a shorter fixed period between deadlines is associated with a higher priority. Rate monotonic scheduling provides a low-overhead, reasonably resource-efficient means of guaranteeing that all users will meet their deadlines provided that certain analytical equations are satisfied during the system design. It avoids the design complexity of time-line scheduling and the overhead of dynamic approaches such as earliest-deadline scheduling.
