| | | | | This is part of a series of posts detailing the steps and learning undertaken to design and implement a CPU in VHDL. Previous parts are available here, and I'd recommend they are read before continuing! Instruction Set Architecture The Instruction Set Architecture (ISA) of a CPU defines the set of operations that can be performed, and on what data types. It explains timing, restrictions, and sometimes any hazards or hardware bugs that can present during normal operation. The operations are defined along ... | |

| | | | | Today, there was an announcement about a new RISC-V chip, which has got a lot of people excited. I wish I could also be excited, but to me, this is just a reminder that RISC architectures are fundamentally unscalable, and inevitably stop being RISC as soon as they need to be fast. People still call ARM a "RISC" architecture despite ARMv8.3-A adding a FJCVTZS instruction, which is "Floating-point Javascript Convert to Signed fixed-point, rounding toward Zero". Reduced instruction set, my ass. | |

| | | [AI summary] The article discusses the process of learning to read x86 assembly language, focusing on how it can be a useful skill for understanding low-level operations of microprocessors. It outlines the challenges of reading assembly, especially in debugging scenarios, and provides an example of translating Ruby code into x86 assembly using Crystal. The article also explains the syntax and structure of x86 assembly, including register usage, instruction suffixes, and the differences between AT&T and Intel syntax. It highlights the complexity of x86 assembly due to its historical evolution and the need for understanding register sizes and operand notation. | ||
