1results about How to "Solve development problems" patented technology

The application discloses a DSP virtualization system and method based on dynamic loading and redirection technology, and the system is realized by cooperation of a HOST side running on a host and a DSP side running on a DSP. The DSP side comprises a DSP firmware module, and the HOST side comprises a DSP Lib module, a vDSP Manager module and a vDSP Lib module. The application realizes concurrent use of single DSP resources by multiple users through the DSP virtualization system, solves the problem that DSP can only be developed and used by a single user, and achieves the purpose of improving the utilization rate of DSP resources. For CPU-DSP collaborative application, a user can flexibly support new DSP API calling requests in a CPU-DSP application program through DSP function blueprint extension and vDSP Lib module extension.
