US 7,024,322 B2 · Dynamic waveform resource management

Abstract

A dynamic waveform manager and an application policy are provided to an electronic device that executes an application requiring the use of waveforms accessed from a waveform table characterized by a limited number of entries. The application policy contains waveform sequencing information specific to the application. The application may utilize any number of waveforms that are typically stored in a memory separate from the waveform table. The dynamic waveform manager monitors the execution of the application, and manages loading and unloading of waveforms required by the application into and out of the waveform table such that each waveform required by the application is loaded in the waveform prior to and at least by the time it is needed by the application. The dynamic waveform manager accesses the application policy to reference the waveform sequencing information specific to the application for use in determining when and which waveforms to load and unload to and from the waveform table.

Dependent claims

An apparatus, comprising:

a processor;
an application program executable by said processor that requires use of a first number of waveforms;
a waveform table comprising a second number of waveform table entries for storing waveforms for use by said application program, wherein said first number exceeds said second number;
an application policy comprising waveform sequencing information specific to said application program;
a dynamic waveform manager that monitors execution of said application program, accesses said application policy to determine which of said first number of waveforms are next required by said application program, and loads one or more of said first number of waveforms into a corresponding respective one or more of said second number of waveform table entries in said waveform table.

A computer readable storage medium tangibly embodying program instructions implementing a method for dynamically managing loading of a plurality of waveforms to a waveform table characterized by a limited number of waveform table entries during execution of an application program, said plurality of waveforms being greater in number than said limited number of waveform table entries, said method comprising the steps of:

determining a subset of said plurality of waveforms to be used first by said application program;
loading of each of said subset of said waveforms to a respective one of said limited number of waveform table entries;
receiving indication of a last use by said application program of a completed one of said loaded waveforms loaded at a corresponding one of said limited number of waveform table entries;
selecting a next waveform still to be used by said application program from said plurality of waveforms that are not currently loaded Into one of said limited number of waveform table entries;
replacing said completed one of said loaded waveforms with said selected next waveform in said one of said limited number of waveform table entries corresponding to said completed one of said loaded waveforms.
