DSP 알고리즘 가속

Dataflow 멀티스레딩 또는 생성된 MEX 함수를 사용한 가속

dspunfold 함수를 사용하여 멀티스레드 MEX 파일을 생성하여 MATLAB^® 함수의 시뮬레이션 처리량을 개선할 수 있습니다.

Simulink^®에서 Dataflow 도메인은 자동으로 모델을 분할하고 여러 스레드를 사용하여 시스템을 시뮬레이션합니다. 시스템에 알고리즘 대기 시간을 추가하면 동시성을 더 높이고 모델의 시뮬레이션 처리량을 개선할 수 있습니다.

함수

`dspunfold`	Generates a multi-threaded MEX file from a MATLAB function
`codegen`	Generate C/C++ code from MATLAB code

블록

문제 해결

Why Does the Analyzer Choose the Wrong State Length?

This section discusses the example where the state length depends on the input which causes verification failure. Debugging steps are also included.

Why Does the Analyzer Choose a Zero State Length?

This section discusses the example where the input does not have an immediate effect on the output. Hence, state length of 0 is considered in spite of the algorithm containing states.
