Abstract: The present disclosure provides a processor having polymorphic instruction set architecture. The processor comprises a scalar processing unit, at least one polymorphic instruction processing unit, at least one multi-granularity parallel memory and a DMA controller. The polymorphic instruction processing unit comprises at least one functional unit. The polymorphic instruction processing unit is configured to interpret and execute a polymorphic instruction and the functional unit is configured to perform specific data operation tasks. The scalar processing unit is configured to invoke the polymorphic instruction and inquire an execution state of the polymorphic instruction. The DMA controller is configured to transmit configuration information for the polymorphic instruction and transmit data required by the polymorphic instruction to the multi-granularity parallel memory. With the present disclosure, programmers can redefine a processor instruction set based on algorithm characteristics of applications after tape-out of a processor.

Abstract: Disclosed are a method and an apparatus for editing audio, an electronic device and a storage medium. The method includes: acquiring a modified text obtained by modifying a known original text of an audio to be edited according to a known text for modification; predicting a duration of an audio corresponding to the text for modification; adjusting a region to be edited of the audio to be edited according to the duration of the audio corresponding to the text for modification, to obtain an adjusted audio to be edited; obtaining, based on a pre-trained audio editing model, an edited audio according to the adjusted audio to be edited and the modified text. In the present disclosure, the edited audio obtained by the audio editing model sounds natural in the context, and supports the function of synthesizing new words that do not appear in the corpus.
