Having now developed its ShBoom 32-bit RISC microprocessor – which will be fabricated for it by National Semiconductor Corp (CI No 2,785), San Diego-based Patriot Scientific Corp is looking around for people to use the thing. It has has now lighted on the Evolve Software subsidiary of television remote controls maker Universal Electronics Inc, and Evolve has agreed to represent the ShBoom to top-tier cable modem, satellite and television set-top box manufacturers around the world. The Patriot ShBoom PSC1000 uses a zero-operand dual-stack architecture with primarily 8-bit instructions for greatly reduced complexity and reduced instruction size. The merged stack-register architecture is claimed to be very efficient for executing stack-oriented environments such as Forth, PostScript and the stack virtual machine internal to Java. The underlying ShBoom architecture is invisible to programmers using Patriot’s ANSI C compiler. The assembly language accepts both native and synthetic register architecture-type instructions.
