| | | | | In this post, we are going to take a deep dive into pointer tagging, where metadata is encoded into a word-sized pointer. Doing so allows us to keep a compact representation that can be passed around in machine registers. This is very common in implementing dynamic programming languages, but can really be used anywhere that additional runtime information is needed about a pointer. We will look at a handful of different ways these pointers can be encoded and see how the compiler can optimize them for diff... | |

| | | Ive went through the first part of From Nand to Tetris course where I learnt to build a simple 16-bit computer called Hack from the digital building blocks (NAND gates). The course used its specific HDL (hardware definition language), which is a gentle way to shield a beginner from the ugliness of a real language, but to implement anything on a real FPGA board one needs to use VHDL or Verilog. | ||
