In absence of any lookups, insert performance over HW UI is estimated at RAM_CLK/60, for example, if RAM_CLK = 300 MHz, the expected insert performance should be around 5M inserts/s. Insert performance drops as the CBCAM gets closer to its maximum capacity and with the increase in lookup rate. To guarantee some minimum insert performance, it is necessary to provide the bandwidth margin RAM_FREQ – (LOOKUP_RATE x TDM_FACTOR).
