How a Redcode “CPU” works The CPU is a machine, it follows a basic mechanism to the beat of an external clock. In the case of a Redcode simulator, every tick of the clock causes the CPU to go through what is called the Fetch-Decode-Execute (FDE) cycle.
Sometimes you have to type out almost identical lines of code, and it’s either time consuming or error prone. Here’s how to avoid it all by using some clever Excel techniques.
How to efficiently store and execute many small functions, without using a single if statement or switch construct. Opcodes Redcode contains 17 opcodes which perform standard operations such as copying data, maths and conditional jumps.
To begin, this isn’t technically an emulator, the system I’m trying to model isn’t real. This is more of a simulator, but that’s less of a catchy search word on the Internet.
