Abstract

Two different operating systems, such as one using Windows real-time extensions and another using Windows NT or other non-real-time operating system, may be implemented on a same system or hardware, such as being co-located on a same processor, without changing client software. Two or more software processes are run on a same processor or system. The software or operating systems communicate using a socket application programming interface. The use of socket communications allows the processes to communicate as if the processes were on different systems. Socket communications between the two operating systems are intercepted by the layered service provider before being provided to the hardware for external transport. The socket communications are re-routed to the socket stack of the destination operating system. The socket communication using sockets is transparent to the application or middleware layer software. By providing for socket communications between two co-located operating systems, the implementation cost and development risk caused by using a shared memory may be avoided.

Claims

1. A method for operating a medical diagnostic ultrasound imaging system, the method comprising:

(a) controlling first operations of the medical diagnostic ultrasound imaging system in real-time with a real-time operating system;

(b) controlling second operations of the medical diagnostic ultrasound imaging system with a non-real-time operating system, the real-time operating system and non-real-time operating systems operable to share hardware of the medical diagnostic ultrasound imaging system; and

(c) communicating between the real-time operating system and the non-real-time operating system with socket communications.

2. The method of claim 1 wherein (a) comprises guaranteeing response time to an external interrupt.

3. The method of claim 1 wherein (a) comprises controlling the first operations based on priority.

4. The method of claim 1 wherein (b) comprises controlling the second operations with round-robin scheduling.

5. The method of claim 1 wherein (a) and (b) comprise the real-time operating system managing the non-real-time operating system as a low priority thread.

6. The method of claim 1 wherein (a) comprises controlling medical imaging and wherein (b) comprises running a user interface with a general application personal computer operating system.

7. The method of claim 1 wherein (c) comprises intercepting socket calls without passing to hardware transport.

8. The method of claim 7 wherein (c) comprises intercepting the socket calls with a layered service provider.

9. The method of claim 7 wherein (c) comprises intercepting the socket calls with a protocol stack of the non-real-time operating system.

11. The method of claim 1 wherein (c) comprises routing a call from the real-time operating system to a set port.

12. The method of claim 1 wherein (c) comprises porting a socket call of one of the real-time and non-real-time operating systems to a socket stream of the other of the real-time and non-real-time operating systems.

13. The method of claim 1 wherein (b) comprises controlling transport with a general application personal computer operating system, and wherein (c) comprises communicating with a service provider interface of the general application personal computer operating system.

14. A method for operating a computer system, the method comprising:

(a) controlling the computer system with a first operating system;

(b) controlling the computer system with second operating system different than the first operating system, the first operating system and second operating systems being co-located; and

(c) communicating between the first operating system and the second operating system with socket communications.

15. The method of claim 14 wherein (a) comprises controlling with real-time extensions.

16. The method of claim 14 wherein (b) comprises controlling the second operations with round-robin scheduling.
