Write Optimized Pentium CodeA series of document on optimizing asm code(by agner fog)This comprehensive manual describes in detail how to write optimized assembly language code, with particular focus on the Pentium(R) microprocessor. It includes many details not found anywhere else. This information will enable you in many cases to calculate exactly how many clock cycles a piece of code will take. The information in this manual is based on research done by me and Karki Jitendra Bahadur. This research has covered only the Pentium Processor. Informations about PentiumPro and MMX processors are based solely on documents from Intel. This article is online from 1487 days and has been seen 2152 times

INTRODUCTION =============== This comprehensive manual describes in detail how to write optimized assembly language code, with particular focus on the Pentium(R) microprocessor. It includes many details not found anywhere else. This information will enable you in many cases to calculate exactly how many clock cycles a piece of code will take. The information in this manual is based on research done by me and Karki Jitendra Bahadur. This research has covered only the Pentium Processor. Informations about PentiumPro and MMX processors are based solely on documents from Intel.
