Microarchitecutre for Resource-Limited Superscalar Microprocessors

摘要

Microelectronic components in space and satellite systems must be resistant to total dose radiation, single-event upset, and latchup in order to accomplish their missions. The demand for inexpensive, high-volume, radiation hardened (rad-hard) integrated circuits (ICs) is expected to increase dramatically as the communication market continues to expand. Motorola's Complementary Gallium Arsenide (CGaAs(TM)) technology offers superior radiation tolerance compared to traditional CMOS processes, while being more economical than dedicated rad-hard CMOS processes. The goals of this dissertation are to optimize a superscalar microarchitecture suitable for CGaAs(TM) microprocessors, develop circuit techniques for such applications, and evaluate the potential of CGaAs(TM) for the development of digital VLSI circuits.
