What is RTL instruction?

RTL, or Register Transfer Level, instructions are a type of low-level programming used in digital circuit design and computer architecture. They describe operations in terms of data transfers between registers and the operations performed on that data, often abstracting away the underlying hardware implementation. RTL instructions are commonly used in hardware description languages (HDLs) like VHDL and Verilog, allowing designers to specify the behavior and structure of electronic systems at a level that is both human-readable and synthesizable into actual hardware.
