About yangminz/bcst_csapp
bcst_csapp is an open-source C language repository that implements core concepts from the textbook 'Computer Systems: A Programmer's Perspective' (CSAPP). It includes a computer simulator that models CPU registers, memory, and an instruction set, along with a linker for ELF-like text formats. The project is part of the BCST (Bilibili Computer Science Topics) initiative by yangminz, accompanied by video explanations on bilibili. It covers topics such as bit and integer representation, floating-point numbers, machine-level program execution, and linking, providing hands-on code examples and a design manual for learners.
