Zusammenfassung: | Techniques are disclosed for the use of a hybrid architecture that combines a programmable processing array and a hardware accelerator. The hybrid architecture dedicates the most computationally intensive blocks to the hardware accelerator, which may be implemented for the computation of pre-distortion (DPD) coefficients while maintaining flexibility for additional DPD computations to be performed by the programmable processing array. An interface is also described for coupling the processing array to the hardware accelerator, which achieves a division of functionality and connects the programmable processing array components to the hardware accelerator components without sacrificing flexibility. This results in a balance between power/area and flexibility. |
