- This manual contains details about the internal working of various microprocessors from Intel, AMD and VIA. Topics include: Out-of-order execution, register renaming, pipeline structure, execution unit organization and branch prediction algorithms for each type of microprocessor. Describes many details that cannot be found in manuals from microprocessor vendors or anywhere else. The information is based on my own research and measurements rather than on official sources. This information will be useful to programmers who want to make CPU-specific optimizations as well as to compiler makers and students of microarchitecture.

- This document contains details about data representation, function calling conventions, register usage conventions, name mangling schemes, etc. for many different C++ compilers and operating systems. Discusses compatibilities and incompatibilities between different C++ compilers. Includes information that is not covered by the official Application Binary Interface standards (ABI's). The information provided here is based on my own research and therefore descriptive rather than normative. Intended as a source of reference for programmers who want to make function libraries compatible with multiple compilers or operating systems and for makers of compilers and other development tools who want their tools to be compatible with existing tools.

ForwardCom: An open standard instruction set for high performance microprocessors
This is a proposal and discussion of how an ideal instruction set architecture can be constructed. The proposed instruction set combines the best from the RISC and CISC principles to produce a flexible, consistent, modular, orthogonal, scalable and expansible instruction set for high performance microprocessors and large vector processors.
The ForwardCom instruction set has variable-length vector registers and a special addressing mode that allows the software to automatically adapt to different microprocessors with different maximum vector lengths and make efficient loops through arrays regardless of whether the array size is divisible by the vector length. Standardization of the corresponding ecosystem of ABI standards, function libraries, compilers, etc. makes it possible to combine different programming languages in the same program.

Test programs for measuring clock cycles and performance monitoring
Test programs that I have used for my research. Can measure clock cycles and performance monitor counters such as cache misses, branch mispredictions, resource stalls etc. in a small piece of code in C, C++ or assembly. Can also set up performance monitor counters for reading inside another program. Supports Windows and Linux, 32 and 64 bit mode, multiple threads.
For experts only. Useful for analyzing small pieces of code but not for profiling a whole program.
