x86/x64 Optimization Manuals, SIMD Library, and the ForwardCom ISA Proposal

This resource collection centers on a five-volume manual series covering low-level performance engineering for x86 and x86-64 processors: C++ optimization, assembly subroutine techniques, Intel/AMD/VIA microarchitecture internals, instruction latency/throughput tables, and cross-compiler calling conventions. The microarchitecture guide stands out because it documents out-of-order execution, register renaming, and branch prediction details based on independent research rather than vendor-published sources.

Beyond the manuals, the toolkit includes practical utilities: a C++ vector class library that exposes SSE through AVX512 SIMD instructions without hand-written assembly, an object file converter/disassembler supporting COFF/PE, ELF, OMF, and Mach-O formats, and lightweight test programs for measuring clock cycles and performance counters in isolated code snippets.

Also featured is ForwardCom, a proposed open instruction set architecture blending RISC and CISC principles with variable-length vector registers designed for scalable, portable vector programming. For compiler engineers, systems programmers, and anyone building cross-platform binary-compatible libraries, this collection offers technical depth rarely found in official documentation.
