Selectable reconfiguration for dynamically reconfigurable IP cores
Systems and methods for reconfiguration of a hardened intellectual property (IP) block in an integrated circuit (IC) device are provided. Reconfiguration of the hardened IP block in the IC device may transition between functions supported by the hardened IP block. A transition may occur as a pre-configured profile is selected to reconfigure the hardened IP block. Further, configuration data associated with each of the pre-configured profiles of the hardened IP block may be generated and storage space to store the configuration data may be created. Additionally, reconfiguration control logic to read and implement the configuration data in hard IP design primitives may also be generated.
1. A tangible, non-transitory, computer-readable medium, comprising instructions to:
receive a plurality of pre-configured profiles, wherein each of the plurality of pre-configured profiles provides a respective distinct configuration of a hardened intellectual property (IP) block, wherein each of the distinct configurations provides a respective distinct functionality in a user design of the hardened IP block;
generate a plurality of sets of configuration data, wherein each of the sets of configuration data is associated with a respective distinct configuration of the hardened IP block;
designate configuration storage space to store the plurality of sets of configuration data; and
generate reconfiguration control logic to read the plurality of sets of configuration data, wherein the reconfiguration control logic is configured to program the hardened IP block with a set of configuration data of the plurality of sets of configuration data to provide a distinct configuration of the hardened IP block that provides a distinct functionality of the hardened IP block.
2. The tangible, non-transitory, computer-readable medium of claim 1 , wherein the plurality of sets of configuration data comprises register settings of the hardened IP block.
3. The tangible, non-transitory, computer-readable medium of claim 1 , comprising instructions to:
determine similarities between the plurality of sets of configuration data that provide distinct configurations; and
reconfigure only portions of the hardened IP block that are dissimilar.
4. The tangible, non-transitory, computer-readable medium of claim 1 , wherein the hardened IP block comprises configurable sets of registers.
5. The tangible, non-transitory, computer-readable memory of claim 1 , wherein the instruction to designate the configuration storage space to store the plurality of sets of configuration data comprises designating storage areas on read-only memory (ROM).
6. The tangible, non-transitory, computer-readable memory of claim 1 , comprising instructions to:
receive commands selecting one or more pre-configured profiles of the plurality of pre-configured profiles; and
reconfigure the hardened IP block with the one or more pre-configured profiles.
7. The tangible, non-transitory, computer-readable memory of claim 1 , comprising instructions to generate user reconfiguration logic that links user input to the reconfiguration control logic.
8. The tangible, non-transitory, computer-readable memory of claim 1 , comprising instructions to program the plurality of sets of configuration data to the hardened IP block via a reconfiguration interface.
9. The tangible, non-transitory, computer-readable memory of claim 1 , wherein the instructions to implement the plurality of sets of configuration data in the hardened IP block comprises reconfiguring the hardened IP block to change to a distinct functionality of the hardened IP block.
