Handel-C is an extension to CeeLanguage that adds parallel constructs (inspired by OccamLanguage). The language is designed for compilation to hardware, e.g. to compile to FPGA netlist or to VHDL. Language, compiler and development environment developed by Celoxia (http://www.celoxica.com/methodology/handelc.asp) BrokenLink.
Some extensions:
par to indicate a parallel block (see CodeOrdering)
chan a channel is a construct allowing synchronization at the hardware signal level, e.g. data that lives in different clock domains where the clocks are not synchronized can be brought together via a chan.
instance counts on functions you specify an upper limit on how many instances of a function may be instantiated in hardware.
rom array like const array, but the hint helps the compiler
