XML defined custom microprocessors using Rapid Hardware Definition Language

Rapid HDL is an object oriented software library for scripting the generation of synthesizable Verilog. A fully functional customized microprocessor is defined and automatically synthesized for an FPGA from an XML specification file. Using a library of blocks, a microprocessor fabric is defined in XML. Control states specify the connections between the fabric blocks during microprocessor operation. Opcodes sequence the control states and provide a vocabulary for assembly programs, which are compiled and executed on the microprocessor.
