Abstract:
A cell phase control device which sends and receives cells between circuits operative in response to a clock signal and a cell phase pulse independent of each other in digital asynchronous transfer mode communication, comprising:a plurality of buffers; writing means responsive to a write pulse signal and a write clock signal for writing cell data into said plurality of buffers in order, and writing cell data simultaneously into said plurality of buffers as required; reading means responsive to a read pulse signal and a read clock signal for reading said cell data from said plurality of buffers in order; and control means for arbitrating writing operation by said writing means and reading operation by said reading means; wherein said writing means, after writing one cell data into a first buffer of said plurality of buffers, writes the subsequent one cell data into a second buffer of said plurality of buffers, said writing means continuously writing, for a fixed time period, the subsequent cell data into said first buffer into which said one cell data has been written.
