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.

Abstract: A system for electroplating a tin-bismuth alloy at near eutectic composition is disclosed. The system includes the plating bath and the process for initially preparing the bath as well as the process for plating an object with tin-bismuth alloy. The system further includes an apparatus for regulating the concentrations of tin and bismuth in the plating bath and the process by which the concentrations are controlled.
