Abstract

A processor-based device (e.g., a wireless device) may include a processor and a semiconductor nonvolatile memory to directly execute an application (e.g., an execute-in-place application) using an associated database. Within a flash memory, in one embodiment, an executable program may be separately stored in a non-fragmented manner from a resident database that includes program management information for use in an execution that does not involve a random access memory, saving time and resources.

Claims

1. A system comprising:

a computing device; and

a non-volatile memory coupled to said computing device, said memory configured to store an executable program in a non-fragmented manner, an associated database that includes registry entries, and a database engine that includes code management software, wherein said executable program, associated database and database engine are stored separately within the non-volatile memory, said computing device configured to execute the program directly from the non-volatile memory based on the code management software being associated with the associated database and linking the executable program to the registry entries included in the associated database, and wherein the program is executed directly from the non-volatile memory without moving the registry entries to a volatile memory.

2. The system of claim 1, said device configured to execute the program based on the program management information in response to an update indication.

3. The system of claim 1, said computing device configured to move the database engine that includes the code management software to the volatile memory.

4. The system of claim 1, said non-volatile memory storing meta information in the program management information of the associated database.

5. The system of claim 1, said non-volatile memory storing an execute-in-place application in one or more objects for the executable program, each one of said one or more objects to hold a portion of the executable program.

6. The system of claim 5, wherein said data base engine is configured to run the execute-in-place application at said non-volatile memory using a schema in one or more objects.

7. The system of claim 6 wherein said data base engine is adapted to store said one or more objects in a binary form at a different location than the program management information of the associated database.

8. The system of claim 1 wherein said non-volatile memory is a flash memory and said system is a wireless communication system.

9. A communication system comprising:

a wireless-enabled computing device including a controller; and

a semiconductor nonvolatile memory coupled to said controller and configured to store an executable program in a non-fragmented manner separately from an associated database that includes registry entries and separately from a database engine that includes code management software, wherein the semiconductor nonvolatile memory is configured to associate the code management software with the associated database and to cause the code management software to link the executable program with the registry entries, and further configured to execute the executable program directly from the nonvolatile memory based on the linked registry entries in response to an update indication without moving the registry entries to a volatile memory.

10. The communication system of claim 9 wherein said semiconductor nonvolatile memory comprising:

meta-information in the registry entries of the associated database;

an execute-in-place application in one or more objects for the executable program, each of said one or more objects to hold a portion of the executable program; and

the database engine to run the execute-in-place application at said semiconductor non-volatile memory using a schema and one or more objects.

11. The communication system of claim 9 wherein said database engine is configured to store said one or more objects in a binary format at a different location than the meta-information in the registry entries of the associated database.

12. A method comprising:

storing an executable program in a non-fragmented manner in a non-volatile memory;

storing a database including registry information associated with the executable program in the non-volatile memory, wherein the database including the registry information is stored separately from the executable program;

storing a database engine in the non-volatile memory, wherein the database engine includes code management software;

associating the database engine with the database including registry information associated with the executable program;

linking, by the code management software, the executable program with the registry information; and

executing, by a controller, the executable program directly from the non-volatile memory based on the registry information associated with the executable program without moving the registry information to a volatile memory.

15. The method of claim 12 including upgrading said program in the non-volatile memory responsive to an update indication.

16. The method of claim 12 including using said database engine to store one or more objects in binary form at a different location than said registry information.

13. The method of aim 12 including storing said program in linear fashion so that it may be directly executed.

14. The method of claim 13 including executing said program in place.

17. A method comprising:

separately storing a program, an associated database of registry information, and a database engine that includes code management software in a non-volatile memory;

receiving a request to update the program;

associating, by a controller, the database engine with the associated database;

linking, by the code management software executed by the controller, the registry information with the program; and

executing, by the controller, said program from said memory in response to said request, using information stored in said associated database of registry information without moving the registry information to a volatile memory.

18. The method of claim 17 including storing said program contiguously in said memory.

19. The method of claim 17 wherein the database engine is stored on a read only memory coupled to said non-volatile memory.
