Abstract

The application relates to various aspects for modeling software, preferably for use in wireless communication devices. One aspect relates to targeting a software model to a plurality of different operating systems/operating system combinations. Another aspect relates to abstracting the operating environment to an operating system/operating system combination. Another aspect relates to handling inter-processor communication. Another aspect relates to a common time manager.

Claims

1. A method for controlling software timing in a multiple operating system environment, the method comprising:

operating system constructs in each of a plurality of operating systems sending callbacks to a time manger;

after a time period specified by each call back, the time manager sending a callback message to a construct associated with the callback; and

the construct operating in response to the callback message.

2. The method of claim 1 wherein the time manager has an associated callback list, the associated call back list is an ordered list of callback time requests of the sent callbacks.

3. The method of claim 1 wherein the time manager has a timer, the timer has a plurality of threads that are waken up in response to expiration of callback time requests.

4. The method of claim 1 wherein the time manager has a timer, the timer scheduling a shortest callback delay and after expiration of the shortest callback delay, scheduling a next shortest callback delay.

5. A time manager for controlling software timing in a multiple operating system environment, the time manager comprising:

an input configured to receive callbacks sent from operating system constructs in each of a plurality of operating systems;

a timer configured to produce a thread after a time period specified by each call back to indicate expiration of a callback to a construct associated with the callback.

6. The time manager of claim 5 wherein the timer scheduling a shortest callback delay and after expiration of the shortest callback delay, scheduling a next shortest callback delay.

7. A wireless communication device comprising the time manager of claim 5;

at least one system processor and at least one communication processor;

a communication module to facilitate communication between each system and communication processor;

a shared memory associated with the communication module; and

each system processor and communication processor having an associated operating system;

8. The wireless communication device of claim 7 wherein the timer scheduling a shortest callback delay and after expiration of the shortest callback delay, scheduling a next shortest callback delay.

9. The wireless communication device of claim 7 wherein the wireless communication device is a wireless transmit/receive unit.

10. A method for software processes to communicate across processor boundaries, the method comprising:

providing a local process associated with a local processor and a remote process associated with a remote processor;

providing a local queue for the local process;

providing or creating a remote queue for the remote process;

the local process having a put request in the local queue indicating a message to be sent to the remote process; and

putting the message in the remote queue.

11. A wireless communication device comprising:

at least one system processor and at least one communication processor;

a communication module to facilitate communication between each system and communication processor;

a shared memory associated with the communication module;

each system processor and communication processor having an associated operating system;

a local process is associated with a local processor of the system and communication processors and a remote process associated with a remote processor of the system and communication processors;

a local queue is associated with the local process; and

a remote queue is associated with the remote process; and

wherein the local process having a put request in the local queue indicating a message to be sent to the remote process; and

putting the message in the remote queue.

12. The wireless communication device of claim 11 wherein the wireless communication device is a wireless transmit/receive unit.
