Micro/370: A 32-bit Single-Chip Microprocessor

This paper reports a 32-bit single-chip microprocessor that directly implements 102 System/370 instructions and supports the emulation of the rest of the instructions. It is fabricated using a 2-µm polysilicon gate NMOS technology with two levels of aluminum. The chip is 10×10 mm2 with 200 000 transistor sites. It is designed for a 10-MHz clock at worst case and has been operated at 18 MHz with 3-W power dissipation. The design and verification methodologies and the testing consideration are also described.
