Using Error Detection Features in User Mode

Table 8-3: CRC Calculation Time in Cyclone V Devices
The following table lists the minimum and maximum time taken to calculate the CRC value:
The minimum time is derived using the maximum clock frequency with a divisor of 0.
The maximum time is derived using the minimum clock frequency with a divisor of 8.
Variant
Cyclone E
Cyclone V GX
Cyclone V GT
Cyclone V SE
Cyclone V SX
Cyclone V ST
