Algorithm 1 TALEN-PCC

Input: Spike event data stream with $N_{events}$   Input: Aggregation time interval $\Delta t$ [ms]   Input: DVS spike sequence duration $T_{seq}$ [ms]   Input: $k_{max}=\frac{T_{seq}}{\Delta t}$   for $k=1$ to $k_{max}$ do    while $t\le k\Delta t$ do        Accumulate flag 0 events. Write event count in an $M\times N$ matrix for flag 0        Accumulate flag 1 events. Write event count in an $M\times N$ matrix for flag 1      end while     Apply raster scan to flag 0 matrix. Extract spatial coordinates (x, y), and event count from the raster scan of flag 0 matrix. Multivariate stream of x, y, Event-count, $k\Delta t$ for flag 0 is input to a file.      Apply raster scan to flag 1 matrix. Extract spatial coordinates (x, y), and event count from the raster scan of flag 1 matrix. Multivariate stream of x, y, Event-count, $k\Delta t$ for flag 1 is input to a file.   end for  Multivariate streams extracted from the raster scans of both the matrices are fed to GPCC encoder.   Spatial coordinates (x, y), and $k\Delta t$ are fed to the positions input of the GPCC encoder.   Event count is fed to the Attributes input of the GPCC encoder.   Output: Polarity 1 compressed bitstream, with size ${\gamma }_1$ (bits)   Output: Polarity 0 compressed bitstream, with size ${\gamma }_0$ (bits)   Output: Total size (bits) of the output stream, $\gamma ={\gamma }_0+{\gamma }_1$
