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 managing an application (app) in an application storage and retrieval space (App Space) comprising one or more apps on a radiofrequency digitization and collection device having a system controller, the method comprising:

registering the app, by the system controller, stored in a local storage of the radiofrequency digitization and collection device by performing the following actions;

determining whether the app can run on the radiofrequency digitization and collection device;

adding the app to the App Space within the radiofrequency digitization and collection device when it is determined that the app can run on the radiofrequency digitization and collection device; and

not adding the app to the App Space when it is determined that the app cannot run on the radiofrequency digitization and collection device;

launching the app from the App Space on the radiofrequency digitization and collection device based on a request;

determining, by the system controller, whether to grant resources and access privileges of components of the radiofrequency digitations and collection device to the app within the App Space in response to a request from the app based on the request for launching the app;

creating a virtual machine, by the system controller, for the app when it is determined to grant the resources and the access privileges to the app;

executing the app in the created virtual machine;

determining whether the app is finished running;

stopping the app when it is determined that the app is finished running; and

performing, by the system controller, teardown of the virtual machine when it is determined that the app is finished running.

2. The method of claim 1, wherein the app cannot run on the radiofrequency digitization and collection device when any combination of at least one of the following is true:

a checksum algorithm run on the app indicates errors;

the app is incompatible with the radiofrequency digitization and collection device;

the app is not licensed; and

the app is not signed.

3. The method of claim 1, further comprising:

monitoring a running app on the radiofrequency digitization and collection device;

determining whether the running app is performing poorly; and

performing actions comprising the following when it is determined the running app is performing poorly;

terminating the running app;

forcing the running app into cleanup mode; and

de-allocating and deregistering the running app'"'"'s resources and privileges.

4. The method of claim 1, further comprising:

monitoring core system functions;

determining whether the core system functions have sufficient resources;

determining whether the app is using system resources when it is determined that the core system functions do not have sufficient resources; and

stopping the app when it is determined that the app is using the system resources.

5. The method of claim 1, further comprising:

monitoring system resources;

determining whether new resources are available; and

performing actions comprising the following when it is determining that the new resources are available;

selecting a suspended app to receive the new resources; and

allocating the new resources to the suspended app.

6. The method of claim 1, further comprising:

adding the app to a user interface; and

displaying an app-specific user interface associated with the app while the app is running.

7. The method of claim 1, wherein the app may be launched locally or remotely.

8. A radiofrequency digitization and collection device having a system controller, comprising:

means for registering, by the system controller, an application (app) stored in a local storage of the radiofrequency digitization and collection device, wherein the means for registering comprises;

means for determining whether the app can run on the radiofrequency digitization and collection device;

means for adding the app to an application storage and retrieval space (App Space) within the radiofrequency digitization and collection device when it is determined that the app can run on the radiofrequency digitization and collection device; and

means for not adding the app to the App Space when it is determined that the app cannot run on the radiofrequency digitization and collection device;

means for launching the app from the App Space on the radiofrequency digitization and collection device based on a request;

means for determining, by the system controller, whether to grant resources and access privileges of components of the radiofrequency digitization and collection device to the app within the App Space in response to a request from the app based on the request for launching the app;

means for creating a virtual machine, by the system controller, for the app when it is determined to grant the resources and the access privileges to the app;

means for executing the app in the created virtual machine;

means for determining whether the app is finished running;

means for stopping the app when it is determined that the app is finished running; and

means for performing, by the system controller, teardown of the virtual machine when it is determined that the app is finished running.
