Dynamic Code Reconfigurability

It is desirable in a system responsive to a user's environment to have the capability of separating program function from program sequence.

An indirect table driven sequence control (directed block processor) is required for functions that may execute in one of several sequences, or where a function may be migrated to an external processor.

The drawing shows a process for separating a function from its fixed sequence. A function generates a request to the directed block processor (DBP) which operates as a sequencer, and to the request parameter list (RPL) which points to an entry in the destination vector table (DVT). The DVT contains a tabular listing of control information and function pointers.

The DBP is a sequence of instructions that creates a sequential execution of a function.
