x86 Programming Information

On this part of the site I have gathered together various information relating to the programming of 386 and later processors. This includes information I have collected from various sources over the last few years (including sites that are long dead), as well as the results of my own work.

Information that will be included once this part of the site is complete will include:

• Instruction Sets and timings
• 
  
• x86 Identification Routines
• 
  
• Optimisation data
• • Processor specific optimisations
  • Code size optimisations
  • Pipelines (for Pentium and later processors)
  • Speed optimisations
  
  
• CPU specific instructions and registers
• 
  
• Memory modes
• • Real Mode
  • Protected Mode
  • Unreal Mode
