Abstract

Systems and methods are presented for allocating resources. In particular, the systems and methods may receive and process a requested SP state to identify for first SP channel information regarding (i) signal processing resources required and (ii) state priority, based on a first state table defining for each of a plurality of states for the first SP channel information regarding signal processing resources required and state priority information; and based on the identified information, arbitrating as between a current state and a requested state. Systems and methods are also provided for fast blanking override of a requested signal processing (SP) state. In particular, the systems and methods may receive a blanking input and automatically override a requested SP state for a first SP channel based on using a first state table to determine blank susceptibility information for the requested SP state.

First claim

The invention claimed is:

1. A system for arbitrating a signal processing (SP) request the system comprising:
an interface block configured for receiving and processing a requested SP state to identify for a first SP channel information regarding (i) signal processing resources required and (ii) state priority, based on a first state table associated with the first SP channel, the first state table defining information for each of a plurality of states for the first SP channel including at least information regarding signal processing resources required and state priority information; and
an arbiter block configured to receive the identified information for the first SP channel regarding the signal processing resources required and the state priority and based thereon arbitrating as between a current state and a requested state;
wherein the interface block is further configured determine whether a blank input automatically overrides the requested SP state;
wherein the first state table further defines blank susceptibility information for each of the plurality of states for the first SP channel and wherein the first state table is used to determine blank susceptibility information for the requested SP state; and
wherein the interface block further includes blanking logic for comparing the blank input relative to the blank susceptibility information for the requested SP state.

2. The system of claim 1 , wherein the blanking logic is implemented utilizing a field programmable gate array.

3. The system of claim 1 , wherein the blank input automatically overrides the requested SP state if the requested state is characterized as susceptible to the blank input.

4. The system of claim 1 , wherein the arbitrating as between a current state and requested state utilizes a field programmable gate array.

5. The system of claim 4 , wherein the arbitrating as between a current state and requested state utilizes subtract and compare circuit architecture (SaCC).

6. The system of claim 1 , wherein the blank susceptibility information defines a set of blanking inputs that would be capable of overriding the requested SP state.

7. The system of claim 1 , wherein the blank susceptibility information is different for different states.

8. The system of claim 1 , wherein the information for each of the plurality of SP states in the first state table further includes information regarding signal processing resources required and state priority information.

9. The system of claim 1 , wherein the automatic overriding of the requested SP state is configured for removing resources associated with the requested SP state from active state.

10. The system of claim 1 , wherein if the requested SP state is overridden, queue logic is configured to perform arbitration on all other active requests in the system for different SP states on a priority basis.

11. The system of claim 1 , wherein the overriding the requested SP state for the first SP channel is configured to free up resources for a different SP state.

12. The system of claim 1 , wherein each SP state is one of a plurality of configurations types of a phased array system, the phased array system including a plurality of elements arranged in a particular geometry, wherein each configuration type is characterized by one or more geometric constraints defining a set of all possible configurations of the phased array that are able to satisfy resource requests of that configuration type, each configuration in the set of all possible configurations including a specific combination of one or more elements of the phased array representing a geometric subset of the phased array.

13. A system for arbitrating a signal processing (SP) request the system comprising:
an interface block configured for receiving and processing a requested SP state to identify for a first SP channel information regarding (i) signal processing resources required and (ii) state priority, based on a first state table associated with the first SP channel, the first state table defining information for each of a plurality of states for the first SP channel including at least information regarding signal processing resources required and state priority information; and
an arbiter block configured to receive the identified information for the first SP channel regarding the signal processing resources required and the state priority and based thereon arbitrating as between a current state and a requested state;
wherein the signal processing resources are RF resources in a phased-array and wherein the priority information for the requested SP state is compared against all quadrants of the phased array.

14. The system of claim 13 , wherein the interface block is further configured determine whether a blank input automatically overrides the requested SP state.

15. The system of claim 14 , wherein the first state table further defines blank susceptibility information for each of the plurality of states for the first SP channel and wherein the first state table is used to determine blank susceptibility information for the requested SP state.

16. The system of claim 15 , wherein the interface block further includes blanking logic for comparing the blank input relative to the blank susceptibility information for the requested SP state.

17. The system of claim 13 , wherein a win/loss is assigned for the requested SP state based on a checking of the most significant digit relative to the comparison results against each of the quadrants.

18. A method for arbitrating a signal processing (SP) request the method comprising:
receiving and processing a requested SP state to identify for a first SP channel information regarding (i) signal processing resources required and (ii) state priority, based on a first state table associated with the first SP channel, the first state table defining information for each of a plurality of states for the first SP channel including at least information regarding signal processing resources required and state priority information; and
based on the identified information for the first SP channel regarding the signal processing resources required and the state priority, arbitrating as between a current state and a requested state;
the method further comprising determining whether a blank input automatically overrides the requested SP state;
wherein the first state table further defines blank susceptibility information for each of the plurality of states for the first SP channel and wherein the first state table is used to determine blank susceptibility information for the requested SP state; and
wherein blanking logic is utilized to compare the blank input relative to the blank susceptibility information for the requested SP state.

19. The method of claim 18 , wherein the blanking logic is implemented utilizing a field programmable gate array.

20. The method of claim 18 , wherein the blank input automatically overrides the requested SP state if the requested RF state is characterized as susceptible to the blank input.

21. The method of claim 18 , wherein the arbitrating as between a current state and requested state utilizes a field programmable gate array.

22. The method of claim 21 , wherein the arbitrating as between a current state and requested state utilizes subtract and compare circuit architecture (SaCC).

23. The method of claim 18 , wherein the blank susceptibility information defines a set of blanking inputs that would be capable of overriding the
