DSP Blockset Release Notes

New Options for Event Detection

The following blocks perform an operation when an event-detecting input port (such as a clock or reset port) detects an event:

Counter Cumulative Product Cumulative Sum Histogram Integer Delay Maximum Mean

Minimum N-Sample Enable Queue RMS Stack Standard Deviation Variance

You can now set the event-detecting ports of the above blocks to respond to one of the following events:

• Non-zero sample -- When the input sample is nonzero
• Rising edge -- When the input does one of the following:
• Rises from a negative value to a positive value or zero
• Rises from zero to a positive value, where the rise is not a continuation of a rise from a negative value to zero (see the following figure)
  
  
• Falling edge -- When the input does one of the following:
• Falls from a positive value to a negative value or zero
• Falls from zero to a negative value, where the fall is not a continuation of a fall from a positive value to zero (see the following figure)
  
  
• Either edge -- When an input is a Rising edge or Falling edge (as described above)
