<p>PURPOSE:To reduce the delay in conversion at a fast data speed and to reduce the quantity of buffer by switching a storage plane of a double buffer for storing signals on a time division multiplex bus where data of a different speed exist in mixture at the switching speed corresponding to each data speed. CONSTITUTION:A write control section 1 switches storage planes at write in buffers 31, 32 at a switching speed in response to the line speed and writes a data on a TDM bus to a relevant area of a selected buffer in response to line number information of a time division multiplex(TDM) control section 4. Moreover, a readout control section 2 selects storage planes for readout of the buffers 31, 32 in response to the line speed and reads out a prescribed quantity of th data in an area corresponding to the buffers in response to the line number from a packet(PKT) control section 5. Thus, the required buffer capacity is reduced and the conversion delay is decreased.</p> |
