The 8 switches correspond to the tuple data input (L-R): Switches 1 & 2: Value of x (2 bits) Switches 3 & 4: Value of y '' Switches 5 & 6: Value of p '' Switches 7 & 8: Value of t ''
The denoiser is implemented as a debouncer. A high or low event will only be output if the data remains the same for 5 clock cycles. Due to white/thermal noise in an event camera, a cluster of coordinates that have no movement may incorectly spike high and the result would be a singular bright bit. The debouncing avoids this by first ensuring the event is consistent before outputting.
Switches (L-R) 5 & 6 corresponds to the input value of the polarity of the tuple. If a high event is wanted - switch 5 should be low and switch 6 should be high. If a low event is wanted = switch 5 must be low, and switch 6 must be low. This will cause the chip to output the debounced tuple corresponding to a high or low event.
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | bit 1 of x | bit 1 of x | |
| 1 | bit 0 of x | bit 0 of x | |
| 2 | bit 1 of y | bit 1 of y | |
| 3 | bit 0 of y | bit 0 of y | |
| 4 | bit 1 of p - no real use | bit 1 of p | |
| 5 | toggles event to be passed through if high | bit 0 of p | |
| 6 | bit 1 of t | bit 1 of t | |
| 7 | bit 0 of t | bit 0 of t |
