摘要

A vector processing engine (VPE) is disclosed that utilizes a format conversion circuit in a data flow path between a vector data memory and an execution unit to provide in-flight format conversion of input vector data to the execution unit for vector processing operations. The Related vector processing systems and methods are also disclosed. The format conversion circuit is provided in the data flow path between the vector data memory in the VPE and the execution unit. The format conversion circuit converts the input vector data sample set fetched from the vector data memory in-flight while the input vector data sample set to be processed is supplied to the execution unit via the data flow path. Composed. In this way, format conversion of the input vector data sample set does not require preprocessing, storage, and refetching from the vector data memory, thereby reducing power consumption and delaying the format conversion preprocessing. Does not limit flow path efficiency. [Selection] Figure 19
