January 17, 2008 - For all of you interested in the various Instruction Set Architecture (ISA) extensions of the X86 processors, we have published an overview of every instruction implemented since the 8086 CPU. In the future, we will provide more detailed information on each and every instruction, and provide information on the supported instruction set and the exceptions for each processor model.

8086-80486 ISA:

• 8086/8088 ISA

• 80486 ISA extensions

Pentium/K6 ISA extensions:

• Intel Pentium ISA extensions
