Abstract

The invention relates to a software system and method for configuring a software system for interaction with a hardware system. In this method, the software system (140) is executed on a host processor interconnected with the hardware system (103). A database (152) is accessed to obtain a description of a set of functional components present within the hardware system (103). A software representation (154) of the capabilities of each functional component is created by using the description of the set of functional components. Then, the software representation (154) is interrogated to determine a set of operational capabilities of the hardware system (103). The software system (140) is then operated in a manner that is responsive to the set of operational capabilities of the hardware system (103).

executing the software system on a host processor interconnected with the hardware system;

accessing a database to obtain a description of a set of functional components present within the hardware system;

creating a software representation of the capabilities of each functional component by using the description of the set of functional components;

interrogating the software representation to determine a set of operational capabilities of the hardware system; and

operating the software system in a manner that is responsive to the set of operational capabilities of the hardware system.

2. The method of

claim 1

, further comprising the step of configuring a user interface of the software system to present only a set of activities that are possible in accordance with the set of operational capabilities.

3. The method of

claim 1

, wherein the software system is a software development system and the hardware system comprises a target system,

wherein the step of interrogating the software representation determines a set of debug capabilities of the target system;

and further comprising the steps of;

selecting a first set of debug activities in accordance with the set of debug capabilities from a plurality of debug activities included within the software development system; and

configuring a user interface of the software development system to present the first set of debug activities, such that remaining debug activities of the plurality of debug activities that cannot be supported by the target system are not included in the user interface.

4. The method of

claim 1

, further comprising the steps of:

receiving a user request to perform a first activity;

interrogating the software representation to determine if a first set of functional components are available to perform the first activity;

initializing the first set of functional components and then performing the first activity; and

repeating the steps of receiving, interrogating, initializing and performing other user requests.

5. The method of

claim 4

, further comprising the steps of:

receiving a user request to perform a second activity;

interrogating the software representation to determine if a second set of functional components are available to perform the second activity; and

indicating that the second activity cannot be performed if the step of interrogating determines a second set of functional components is not available to perform the second activity.

6. The method of

claim 4

, further comprising the steps of:

updating the set of software representations to indicate that one or more corresponding functional components are present but not available because it is being used to perform the first activity;

receiving a user request to perform a third activity;

interrogating the software representation to determine if a third set of functional components are available to perform the third activity; and

indicating that the third activity cannot be performed currently if the step of interrogating determines a third set of functional components is present to perform the third activity, but that a portion of the third set of functional components is currently not available.

7. The method of

claim 4

, further comprising the step of updating the software representation to indicate that one or more corresponding functional components are present but not available because it is being reserved to perform another activity

8. The method of

claim 4

, wherein the step of initializing the first set of functional components comprises the step of sending a command to the hardware system to enable a first mode of operation.

9. The method of

claim 1

, wherein the step of creating the software representation forms a set of software components wherein each of the software components corresponds to a single unique functional component of the hardware system.
