Abstract
A virtual counter for dynamically calculating memory addresses at a digital switch that receives data streams of different data rates. The switch has a memory that is divisible into partitions with each partition being divisible into multiple locations. A virtual counter is implemented for each data stream in a rate conversion architecture at the switch to optimize usage of the switch memory. An input virtual counter is used to calculate a data memory address and an output virtual counter is used to calculate a connection memory address.
