Distributed switching system |
摘要 |
A distributed switching system (20) is provided for implementation in an integrated circuit utilizing a switching bus (30) in which bus lines (30a-30n) are time division multiplexed serial data streams consisting of time slots used for both transmit and receive directions. The distributed switching system (20) includes a bus line selector (31) to select one of the plurality of bus lines (30a-30n) to perform space switching functions. A slot counter (32) is provided for selecting one of a plurality of time slots on the plurality of bus lines (30a-30n) to perform a time switching function. Interface shift registers (33, 35) are interconnected for transmitting to and receiving data from the switching bus (30). Interconnected to the bus registers (33, 35) is a line interface register (34) for transmitting to and receiving data from a digital instrument.
