I built a 'slice of function pointers' bytecode interpreter in Go in 2019 for the Algorand VM (Blockchain smart contract stuff) and before that the same pattern in C for a toy JVM around 2005. It's a good pattern! The Algorand VM was focused on low overhead running thousands of tiny programs per second. Version 1 had no loops and a 1000 instruction limit. The JVM was focused on low memory, towards possible embedded microcontroller use. So, 'array of function pointers' is nothing new, but it is a good pattern. |
