VLSI array processor R&D status report

Detail design of the Arithmetic Processor Unit (APU) chip has been completed. All cell types (100) have been run through the design rule check (DRC) programs, corrected and verified. DRC runs on the entire chip have been run and all corrections have been made. Fifteen out of eighteen of the chip DRC corrections have been verified. The metal, polysilicon and information data layers of the APU layout is shown. The attached drawings, titled 'VLSI Array Processor Arithmetic Processor Unit Chip Plan' is a detail drawing of the APU Chip Plan. The functional level simulator of the APU has been built and verified using a set of APU diagnostic code. A gate level logic simulation of the APU has been built. The APU breadboard modules have been fabricated and check out has been initiated. The Array Processor Demonstration System (APDS) modules are in the wire-wrap process. The APDS and APU microcode assembler have been built and checked out. The linker and loader for the APDS have also been built.
