ABSTRACT:
Access by a function to a collective resource is controlled by requiring that the function waits for a minimum number of clock cycles CLK called latency [LAT] between two successive accesses of the function. The function is further required to wait a number of cycles called penalty [PEN] which is higher than the latency between two successive accesses when a given number of successive accesses separated in time by at least the value of the latency has taken place beforehand. Registers [REG1, REG2] are decremented (or incremented) with each clock cycle and incremented (or decremented) with each access of the function to the collective resource. Tests [T1, T3, T4] are made with the contents of the registers to authorize [GRT] the access to the collective resource.
