hex.and.init¶

This is where the and “truth” tables are.
Its 8-bits are expected to be {src<<4 | dst} at the jump to it (for the src,dst hexes of the and operation).
Its 8-bits are expected to be 0 after the jump to it.

Signature¶

def init @ switch, clean_table_entry, end < ..tables.res > dst { ... }

Defined in hex/logics.fj — lines 338–358 (view on GitHub).

Complexity¶

  • Time: 6 (when jumping to dst, until finished)

  • Space: 595

See the complexity glossary for what @, w, dw, dbit, n mean.

Requires init¶

The following must be initialised before this macro is invoked:

  • hex.tables.init_shared (or hex.init)

Output labels¶

This macro exposes labels into the caller’s scope via >:

  • dst — This variable is an 8-bit variable (in a single op, [dbit,dbit+8)).
