| 摘要 |
The present invention relates to a system for checking and adjusting a transmission buffer (1), wherein a bit stream (11) incoming to the transmission buffer (1) has a first transmission frequency (f1) or bit rate, and wherein a bit stream (12) outgoing fromthe transmission buffer (1) has a second transmission frequency (f2) or bit rate. A write-related pointer (15) is given a value which corresponds to a bit position into which a writing unit (13) writes from the incoming bit stream (11) into the transmission buffer (1), and a read-related pointer (16) is given a value which corresponds to a bit position from which a reading unit (14) reads from the transmission buffer (1) into the outgoing bit stream (12). A checking and adjusting means includes a proportional part (2), and integrating part (3) and an adjusting part (5) and functions to check and adjust the bit distance between the writing unit (13) and the reading unit (14). The proportional part (2) operates at a first clock frequency and the integrating part (3) operates at a second clock frequency, wherein the second clock frequency is allocated a lower value than the first clock frequency. |
