only.Expand description
A Program for the recursion circuit (e.g. lift_20 or join).
The recursion circuit is an application specific virtual machine with a limited instruction set, no control flow operations, and a write-once memory tape. Although it is not general purpose, it can load and execute a program, similar to the rv32im zkVM.
Programs for the recursion circuit are loaded into the control columns, which is a set of public columns in the witness. Programs are therefore identified by their control ID, which is similar but not the same as the image ID used to identify rv32im programs.
Fields§
§code: Vec<Elem>
The code of the program, encoded as Baby Bear field elements.
code_size: usize
The number of code columns.
po2: usize
1 << po2 is the number of cycles executed.
