Journal ArticleDOI
Circuit techniques in a 266-MHz MMX-enabled processor
Donald A. Draper,Matthew P. Crowley,John C. Holst,G. Favor,Albrecht Schoy,Jeffrey E. Trull,Amos Ben-Meir,R. Khanna,Dennis L. Wendell,R. Krishna,J. Nolan,D. Mallick,Hamid Partovi,Mark E. Roberts,M. Johnson,Thomas H. Lee +15 more
TL;DR: The AMD-K6 MMX-enabled processor is plug-compatible with the industry-standard Socket 7 and is binary compatible with the existing base of legacy X86 software.
Patent
Integration of multi-stage execution units with a scheduler for single-stage execution units
TL;DR: A superscalar processor includes a central scheduler for multiple execution units as discussed by the authors, which presumes operations issued to a particular execution unit all have the same latency, even though some of the operations have longer latencies, e.g., two clock cycles.
Proceedings ArticleDOI
An X86 microprocessor with multimedia extensions
Donald A. Draper,Matthew P. Crowley,John C. Holst,Greg Favor,Albrecht Schoy,Amos Ben-Meir,Jeffrey E. Trull,R. Khanna,Dennis L. Wendell,R. Krishna,J. Nolan,Hamid Partovi,M. Johnson,Thomas H. Lee,D. Mallick,G. Frydel,A. Vuong,S. Yu,R. Maley,B. Kauffmann +19 more
TL;DR: This sixth-generation X86 instruction-set compatible microprocessor implements a set of multimedia extensions that uses two-level branch prediction based on an 8192-entry branch history table, a 16- entry branch target cache and a 16,entry return address stack to identify instruction boundaries.
Proceedings ArticleDOI
A 0.25 mm x86 microprocessor with a 100 MHz socket 7 interface
R. Khanna,Amos Ben-Meir,L. DiGregorio,Donald A. Draper,R. Krishna,R. Maley,A. Mehta,S. Oberman,L. Tsai,T. Williams +9 more
TL;DR: The AMD-KG 3D MMX enabled processor is an enhanced follow-on to the AMD- KG MMXenabled processor and implements 19 floating-point (FP) vector operations to enhance 3D graphics and audio performance.
