Method and apparatus for software-based allocation and scheduling of hardware resources in an electronic device
View Patent ↗An architecture and method for dynamic resource allocation and scheduling in a communication device is disclosed herein. The method of controlling hardware resources in a communication device having a processor, a computer readable memory, and at least one hardware resource coupled to each other includes several steps. The first step locates a memory address in the computer readable memory that is associated with a first hardware resource. In the next step, control information associated with the first memory address is transmitted to the first hardware resource for it to be operated. In the last step, a pointer associated with the first address that locates a subsequent address for a subsequent hardware resource, is read.
1. A method of dynamically implementing changes for scheduling at least one hardware resource of a wireless communication device, comprising the steps of:
a) receiving a first list of addresses associated with the at least one hardware resource, the first list of addresses listing active operation information for the at least one hardware resource;
b) receiving a second list of addresses associated with the at least one hardware resource, the second list of addresses listing backup operation information for the at least one hardware resource;
c) receiving a request to modify an operation of the at least one hardware resource in a given category;
d) modifying the second list of addresses to reflect the request to modify the operation of the at least one hardware resource;
e) exchanging the active/backup status of the first list of addresses and the second list of addresses;
f) duplicating the active second address list as replacement for the backup first list of addresses; and
g) operating the at least one hardware resource according to the modified active-status second list of addresses.
2. An apparatus for dynamically implementing changes for scheduling at least one hardware resource in a wireless communication device comprising:
memory means for receiving and storing a first list of addresses associated with the at least one hardware resource, the first list of addresses listing active operation information for the at least one hardware resource;
memory means for receiving and storing a second list of addresses associated with the at least one hardware resource, the second list of addresses listing backup operation information for the at least one hardware resource;
controller means for receiving a request to modify an operation of the at least one hardware resource in a given category;
said controller means operating for:
modifying the second list of addresses to reflect the request to modify the operation of the at least one hardware resource;
exchanging the active/backup status of the first list of addresses and the second list of addresses;
duplicating the active second address list as replacement for the backup first list of addresses; and
operating the at least one hardware resource according to the active modified second list of addresses.
