| | | | | [AI summary] This article dives into the internals of the RI5CY core, a 4-stage in-order pipelined RISC-V core. It discusses the decoder and register file, essential for customizing the core, particularly for adding new instructions and integrating cryptographic extensions like XCrypto. The article also compares RISC-V's compressed instructions with ARM's Thumb mode, highlighting differences in code density and implementation. | |

| | | | | [AI summary] The text provides an in-depth exploration of various x86-64 instruction set architectures, focusing on arithmetic operations (ADD, SUB, MUL, SMUL, DIV, SDIV), logical operations (AND, OR, XOR, NOT), and control flow instructions. It details the implementation of these instructions in the QBX virtual machine, emphasizing how they emulate real x86-64 instructions while managing the flags register and handling different operand sizes (8-bit and 16-bit). The text also discusses the nuances of flag handling, register operations, and macro-based code generation to streamline instruction implementation. | |
