Class AllTestsActivity

  • java.lang.Object
    • Activity
      • br.usp.ime.dspbenchmarking.activities.AllTestsActivity

  • public class AllTestsActivity
extends Activity
    An activity that performs all tests in a device. Tests are divided in 2 phases: Phase 1: measurement of time taken to perform common tasks (loopback, FFT, IIR filtering, etc). Phase 2: stress tests (convolution, additive synthesis, etc). During this phase, each algorithm is run with increasing complexity until the device limit is reached (i.e. until the computation period becomes bigger than the theoretical DSP period). Then, a binary search is performed to find the maximum parameter feasible for that algorithm. All tests use one DSP thread, which is subsequently suspended and resumed between tests execution. One DSP control thread is started that keeps watching the DSP thread and controls tests execution and results gathering.
