Abstract
An idle address controller for a shared buffer type ATM switch controls the addresses of output cells in a common memory to be stored directly in an idle address buffer without passing through the conventional idle address delay controller, by improving the idle address control scheme of a unit switch. The idle address controller includes an idle address control signal generator for generating idle address control signals based on the buffer length information from counters, idle address control signal buffers for storing the idle address control signals, and an idle address control signal multiplexer. Therefore, the idle addresses can be efficiently provided, and this mechanism lowers cell loss and reduces required memory capacity.
