About Vulcan ASIC Ltd.
Vulcan ASIC was founded in April 1996 to address the fast-growing market for ASIC consulting services and intellectual property integration. The company has provided expertise to many major systems developers to help get complex systems to market on time, including sourcing and integrating virtual components. In 1998 Vulcan saw the opportunity for a compact yet powerful embedded processor that could be implemented in both CPLD and ASIC technology. Vulcan evaluated the market and chose to develop a core based on the Java[tm] language feeling it offers a safer, easier to program, more compact and standardized solution than most RISC cores programmed in C/C++.
