Techniques are disclosed for the use of a hybrid architecture that combines a programmable processing array and a hardware accelerator. The hybrid architecture functions to maintain synchronization between data samples to be transmitted and a measured or observed transmission of the data samples. By comparing these blocks of data samples, DFE functions such as digital pre-distortion (DPD) parameter adaptation may be implemented. The hybrid architecture enables high flexibility at low additional cost. To further limit the costs, the programable processing array may have processing power and memory that is reduced compared to conventional processing array implementations.

Data synchronization techniques for a hybrid hardware accelerator and programmable processing array architecture

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.

Techniques are disclosed for the use of fused vector processor instructions by a vector processor architecture. Each fused vector processor instruction may include a set of fields associated with individual vector processing instructions. The vector processor architecture may implement local buffers facilitating a single vector processor instruction to be used to execute each of the individual vector processing instructions without re-accessing vector registers between each executed individual vector processing instruction. The vector processor architecture enables less communication across the interconnection network, thereby increasing interconnection network bandwidth and the speed of computations, and decreasing power usage.

Vector processor utilizing massively fused operations

Techniques are disclosed for a vector processor architecture that enables data interpolation in accordance with multiple dimensions, such as one-, two-, and three-dimensional linear interpolation. The vector processor architecture includes a vector processor and accompanying vector addressable memory that enable a simultaneous retrieval of multiple entries in the vector addressable memory to facilitate linear interpolation calculations. The vector processor architecture vastly increases the speed in which such calculations may occur compared to conventional processing architectures. Example implementations include the calculation of digital pre-distortion (DPD) coefficients for use with radio frequency (RF) transmitter chains to support multi-band applications.

Techniques are disclosed for the use of a hybrid architecture that combines a programmable processing array and a hardware accelerator. The hybrid architecture implements a data driven synchronization process to maintain synchronization between the programmable elements (PEs) of the programmable processing array. The hybrid architecture implements a timer-based solution to ensure data-driven synchronization between the PEs of the programmable processing array meets the time-based synchronization requirements of the overall system. The timers function to introduce a delay or latency to the time required by each of the PEs of the programmable processing array to perform their respective tasks, thereby forcing the hardware blocks to wait to receive the processed data samples output via the PEs and perform their hardware-based computations.
