Abstract
A system comprises a system interface to receive one or more instruction sets from a microcontroller and to receive digital data to be processed. The system further comprises a controller that is reconfigurable according to the one or more instruction sets received by the system interface. The system further comprises a data path device to perform digital filtering operations on the digital data as directed by the controller according to the reconfiguration of the controller by the one or more instruction sets.
Claims20
A system comprising:
- a system interface to receive one or more instruction sets from a microcontroller and to receive digital data to be processed;
- a controller that is reconfigurable according to the one or more instruction sets received by the system interface;
- and
- a data path device to perform digital filtering operations on the digital data as directed by the controller according to the reconfiguration of the controller by the one or more instruction sets.
1 more element
A method comprising:
- populating a controller with data path instructions and populating a data path device with one or more filter coefficients;
- receiving digital data to be digitally processed according to the data path instructions in the controller and the filter coefficients in the data path device;
- locating one or more data path instructions in the controller responsive to receiving the digital data, wherein the data path instructions are configured to identify one or more filter coefficients in the data path device;
