JHDL

JHDL is the acronym for Just Another hardware definition language and is an open source project, which began in the Brigham Young University in 1997.

The idea of JHDL is so implement in Java programs written in VHDL that ensure that programmed FPGA (or networked FPGAs) reaches a state described by objects of the program data flow between the physical terminals of an electronic component.

The goal is that in the available FPGA network objects are created exactly as is common in normal Java programs, namely by statements of the form " Object reference = new Object Type ( parameter ) ". By simply forget the reference used by their resource area will be released (in the case of JHDL logic gates ).

JHDL is particularly interesting in the context of self-configuring systems. It is conceivable that in the future an open- source operating system operates on an open- source hardware platform, which are calculated by means of one or more high-density FPGAs. As can exist simultaneously in such a network, many objects and a large number of threads (data and program flows) operate simultaneously can here possibly even at lower clock rates than the usual new optimized CPUs, a new area of ​​computer technology ( computer architecture, processor architecture) arise.
