v16 v17 4 4 '''Hardware Changes''' 5 5 * Updated clock config core to latest version (fixes bad default values for en/disabled outputs) 6 * Replaced ofdm_timer with new warp_timerperipheral (now includes four independent timers)7 * Reworked Rx PHY to clockFFT at system clock (40MHz).8 * This reduces the Rx latency by 4µsec.DATA-ACK turnaround now 19.8µsec.9 * This also helps CFO, allowing the pilot tones to apply corrections one OFDM symbol earlier.6 * Replaced ofdm_timer with new [source:/ResearchApps/PHY/TIMER warp_timer] peripheral (now includes four independent timers) 7 * Reworked PHY to clock Rx FFT at system clock (40MHz). 8 * This reduces the Rx latency by ~4µsec; DATA-ACK turnaround now 19.8µsec. 9 * This also helps CFO, allowing the pilot tones to apply phase corrections one OFDM symbol earlier. 10 10 * Redesigned pilot tone phase averaging to reduce intra-symbol variance. 11 * Re-added shared memories for flexible Tx/Rx modulation (these were removed in v10 due to Sysgen limitations).11 * Re-added shared memories for flexible Tx/Rx modulation (these were removed in v10 due to Sysgen 10.1.00 limitations). 12 12 * Added [wiki:HardwareUsersGuides/UserIOBoard_v1.0 User I/O board] controller 13 13 * Added interrupt for UART
