Abstract

A multi-master system includes a first master, a second master, and an integrated control circuit controlled by each of the first and second masters. The integrated control circuit includes a first dedicated block configured to provide a first function to the first master, a second dedicated block configured to provide a second function to the second master, and a global using block configured to provide a common function to each of the first and second masters.

First claim

What is claimed is:

1. A multi-master system comprising:
a first master;
a second master; and
an integrated control circuit controlled by each of the first and second masters,
wherein the integrated control circuit comprises:
a bias block configured to provide at least one bias required to perform functions of the integrated control circuit;
a first dedicated block configured to provide a first function to the first master;
a second dedicated block configured to provide a second function to the second master; and
a global using block configured to provide a common function to each of the first and second masters, and

wherein the bias block is an un-configurable block which cannot be set up by the first and second masters,
wherein the global using block is controlled by one of the first and second masters,
wherein the integrated control circuit further comprises a first selection register configured to store information associated with the first function and the common function and a second selection register configured to store information associated with the second function and the common function,
wherein the first selection register includes a first available configuration register which stores a first setup information of the common function for the first master, the first setup information being determined by the first master, and
wherein the second selection register includes a second available configuration register which stores a second setup information of the common function for the second master, the second setup information being determined by the second master.

2. The multi-master system of claim 1 , wherein the bias block includes a bandgap reference generator, an oscillator or a current source.

3. The multi-master system of claim 1 , wherein the first selection register includes a first bias register configured to store flag information associated with the bias block, and
the second selection register includes a second bias register configured to store the flag information.

4. The multi-master system of claim 1 , wherein the first selection register includes the first available configuration register configured to store information associated with the first function and configured to store information associated with the common function, and
the second selection register includes the second available configuration register configured to store information associated with the second function and configured to store information associated with the common function.

5. The multi-master system of claim 4 , wherein the global using block is controlled by one of the first and second masters according to values stored in the first and second available configuration registers.

6. The multi-master system of claim 4 , wherein the global using block is controlled by an external electronic control unit of the multi-master system according to values stored in the first and second available configuration registers.

7. The multi-master system of claim 4 , wherein the integrated control circuit comprises:
a master selection unit configured to generate a selection signal according to values stored in the first and second available configuration registers; and
a multiplexer configured to select whether to connect the first master to the global using block or to connect the second master to the global using block in response to the selection signal.

8. The multi-master system of claim 1 , further comprising:
a first interface configured to perform serial communication between the first master and the global using block; and
a second interface configured to perform serial communication between the second master and the global using block.

9. An operating method of a multi-master system, the operating method comprising:
setting up specific use blocks configured to provide a specific use function to each of masters depending on first register setup;
setting up a global using block configured to provide a common function of the masters depending on second register setup; and
setting up a bias block configured to provide a bias required for the specific function depending on third register setup,
wherein the second register setup is performed in response to a serial peripheral interface (SPI) command of each of the masters,
wherein the global using block is controlled by one of the masters,
wherein the bias block is an un-configurable block which cannot be set up by the masters,
wherein a first selection register is configured to store information associated with a first function and the common function and a second selection register is configured to store information associated with a second function and the common function.

10. The operating method of claim 9 , wherein setting up the bias block comprises:
copying flag information corresponding to the bias; and
storing the copied flag information in corresponding bias registers.

11. The operating method of claim 9 , wherein setting up the specific blocks comprises:
storing information associated with the specific use function in an available configuration register.

12. The operating method of claim 9 , wherein setting up the global using block comprises:
storing information associated with use of the common function in an available configuration register corresponding to each of the masters.

13. The operating method of claim 9 , wherein the information associated with use of the common function includes information on whether it is unused, information associated with a master using the common function or error information.
