Zusammenfassung:An example core for data processing engine (DPE) includes a first register file configured to provide a first plurality of output lanes, a processor, coupled to the register file, including: a multiply-accumulate (MAC) circuit, and a first permute circuit coupled between the first register file and the MAC circuit. The first permute circuit is configured to generate a first vector by selecting a first set of output lanes from the first plurality of output lanes, and a second permute circuit coupled between the first register file and the MAC circuit. The second permute circuit is configured to generate a second vector by selecting a second set of output lanes from the first plurality of output lanes.
