Abstract
A system and method for executing conditional branch instructions by a processor using dynamic branch address tables containing branch target addresses. The branch target addresses are selected by the result of a computation of fields in the branch instruction and an index generated during the execution of previous instructions. The relevant fields include the base address of a branch address table and a mask value. The contents, size, and location of the branch address tables in a random-access-memory local store may be changed during run-time by program control.
