    v16 v17  
    44'''Hardware Changes'''
    55 * Updated clock config core to latest version (fixes bad default values for en/disabled outputs)
    6  * Replaced ofdm_timer with new warp_timer peripheral (now includes four independent timers)
    7  * Reworked Rx PHY to clock 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 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.
    1010 * 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).
    1212 * Added [wiki:HardwareUsersGuides/UserIOBoard_v1.0 User I/O board] controller
    1313 * Added interrupt for UART
