Logic Sniffer 103
Run Length Encoding is a compression method that records the time between logic changes, instead of snapshot of the logic at each point in time.
- A common issue is that sampling never ends. This will happen if there are no changes to record.
- The highest channel is not available in RLE modes. It is used in the RLE protocol.
See updates for the v3 Demon Core that supports RLE
The highest channel is not available in RLE modes. It is used in the RLE protocol to encode the sample as a no change measurement or a change measurement.
RLE extends the total samples possible, but it will still use all the samples if there is no change in pin data.
|Groups||RLE bits||MAX samples*||Duration at 100MHz|
|2||15bit||196 million||2 seconds|
|4||31bit||6.4 trillion||17.9 hours|
MAX samples* based on:
- (total sample width/2) * (max value for RLE bits) = max samples
- (24K/2) * 128 = 1.5 million samples
- (12K/2) * 32768 = 196 million samples
- (8K/2) * = 67.1 billion samples
- (6K/2) * 2147483647 = 6.4 trillion samples.
