Apparatus and methods are provided for controlling the loading status of DLLs. Specifically, a streaming program compiler is provided. The compiler includes operation modules for calling DLLs during streaming program execution; association table generating units for generating association tables according to user-defined rules, where the association table includes entries indicating (i) stream branches of the streaming program and (ii) an operation module corresponding to the stream branches; and a trigger generating unit for generating a trigger based on user-defined rules, where the trigger generating unit (i) determines which conditions for loading and unloading DLLs fit the streaming program, (ii) matches these conditions to a particular stream branch to identify a matched stream branch, and (iii) sends out triggering signals indicating the matched stream branch. This invention also provides a corresponding method and controller.

A system enabling Transactional Memory with overflow prediction mechanism, comprising: prediction unit for predicting the mode for the next execution of a transaction based on the final status of the previous execution of the transaction; execution unit for executing the transaction in the execution mode predicted by the prediction unit, wherein the execution mode comprises overflow mode and non-overflow made. According to this invention, before a transaction is executed, it is predicted whether or not the transaction will overflow, and therefore, the execution of the transaction which is necessary to determine whether or not an overflow will occur is saved.
