Power considerations in the design of the Alpha 21264 microprocessor
M.K. Gowan, L.L. Biro, D.B. Jackson · 2002
Power dissipation is rapidly becoming a limiting factor in high performance microprocessor design due to ever increasing device counts and clock rates. The 21264 is a third generation Alpha microprocessor implementation, containing 15.2 million transistors and operating at 600 MHz. This paper describes some of the techniques the Alpha design team utilized to help manage power dissipation. In addition, the electrical design of the power, ground, and clock networks is presented.
