Abstract

An RF digitization and collection system (RFDCS) and methods for implementing the RF digitization and collection system to manage an application storage and retrieval space (App Space), wherein the App Space includes apps that may perform various offline and/or real-time transforms of RF signals received, stored, or played back on the RFDCS. Also, in the various embodiments, the RFDCS may govern the system resources available to these apps while ensuring that the RFDCS'"'"'s core system functions are not impacted by the execution of one or more of these apps in the App Space. Thus, the RFDCS may enable users to utilize real-time signal processing by running various specialized apps without compromising the RFDCS'"'"'s core system function, thereby promoting dynamic “on-the-fly” transformation of raw RF signals without compromising the user'"'"'s overall experience.

Claims

1. A method of executing an application (app) in an application storage and retrieval space (App Space) on a radiofrequency digitization and collection device comprising a system, comprising:

registering by the app and the system, the app with the system;

requesting resources and privileges from the system, by the app, in response to the app being launched;

responding to a request for resources and privileges from the app by the system;

determining, by the app, whether the system granted the resources and the privileges;

registering, by the app, the app'"'"'s transforms with the system comprising;

determining whether all transforms have been registered; and

performing the following when it is determined that all transforms have not been registered;

attempting to register unregistered transforms with the system;

determining whether a reattempt timer has expired;

determining whether to continue without registering all transforms when it is determined that the reattempt timer has expired; and

not running on the system when it is determined not to continue without registering all transforms;

performing, by the app, the registered transforms;

determining, by the app, whether the app is finished performing transforms; and

releasing privileges and resources back to the system, by the app, when it is determined that the app is finished performing transforms.

2. The method of claim 1, wherein releasing privileges and resources back to the system comprises:

deregistering filters;

deregistering all transforms; and

freeing allocated memory.

3. A radiofrequency digitization and collection device, comprising:

means for registering an app with a system;

means for requesting resources and privileges from the system in response to the app being launched;

means for responding to a request for resources and privileges from the app by the system;

means for determining whether the system granted the resources and the privileges;

means for registering the app'"'"'s transforms with the system comprising;

means for determining whether all transforms have been registered; and

means for performing the following when it is determined that all transforms have not been registered;

attempting to register unregistered transforms with the system;

determining whether a reattempt timer has expired;

determining whether to continue without registering all transforms when it is determined that the reattempt timer has expired; and

not running on the system when it is determined not to continue without registering all transforms;

means for performing the registered transforms;

means for determining whether the app is finished performing transforms; and

means for releasing privileges and resources back to the system when it is determined that the app is finished performing transforms.

4. The radiofrequency digitization and collection device of claim 3, wherein means for releasing privileges and resources back to the system comprises:

means for deregistering filters;

means for deregistering all transforms; and

means for freeing allocated memory.

5. A non-transitory processor-readable storage medium having stored thereon processor-executable software instructions configured to cause a processor of a radiofrequency digitization and collection device to perform operations for executing an application (app) in an application storage and retrieval space (App Space) comprising one or more apps, the operations comprising:

registering, by the app and the system, the app with a system;

requesting resources and privileges from the system, by the app, in response to the app being launched;

responding to a request for resources and privileges from the app by the system;

determining, by the app, whether the system granted the resources and the privileges;

registering, by the app, the app'"'"'s transforms with the system comprising;

determining whether all transforms have been registered; and

performing the following when it is determined that all transforms have not been registered;

attempting to register unregistered transforms with the system;

determining whether a reattempt timer has expired;

determining whether to continue without registering all transforms when it is determined that the reattempt timer has expired; and

not running on the system when it is determined not to continue without registering all transforms;

performing, by the app, the registered transforms;

determining, by the app, whether the app is finished performing transforms; and

releasing privileges and resources back to the system, by the app, when it is determined that the app is finished performing transforms.

6. The non-transitory processor-readable storage medium of claim 5, wherein the stored processor-executable software instructions are configured to cause a processor of a radiofrequency digitization and collection device to perform operations such that releasing privileges and resources back to the system comprises:

deregistering filters;

deregistering all transforms; and

freeing allocated memory.
