\|	\|	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.	7.3 parsecs away Travel

\|		There are several commonly used RISC-V instruction pairs with 32-bit immediates. Below is an example of loading a 32-bit immediate into a register using lui/addi: lui rd,imm[31:12] addi rd,rd,imm[11:0] Here lui places a (sign-extended) 20-bit immediate into register rd and fills the lowest 12 bits with zeros, and addi adds a sign-extended 12-bit immediate to register rd.	38.7 parsecs away Travel
