摘要： A sending data buffer for holding sending data temporarily and transmitting the data to an echo canceler section is installed between a sending section and an echo canceler section of an echo canceler integrated circuit included in a subscriber line circuit of the integrated service digital network. The sending data buffer is operated in shift register mode in sending training mode, and operated in FIFO (first in first out) mode in sending/receiving training mode. Also adjustment function of the delay amount corresponding to the use setting is added.
摘要翻译：用于暂时保持发送数据的发送数据缓冲器被安装在综合业务数字网络的用户线电路中的回波消除器集成电路的发送部分和回波消除器部分之间，并将数据发送到回波消除器部分。发送数据缓冲器在发送训练模式下以移位寄存器模式运行，并在发送/接收训练模式下以FIFO（先进先出）模式运行。还增加了与使用设置对应的延迟量的调整功能。

摘要： Disclosed is a data processor comprising a micro ROM 201, an instruction decoder 1DEC, a repeat controller 207 and a first and a second instruction register IR1, IR2. The instruction decoder 1DEC decodes a repeat instruction read from the micro ROM 201 and thereby furnishes the repeat controller 207 with an internal state requiring specific instructions following the repeat instruction to be executed repeatedly. In turn, the repeat controller 207 reads the instructions to be repeated in series from the micro ROM 201 and places them into the first and second instruction registers IR1, IR2 for execution. Then with access to the micro ROM 201 inhibited, the instructions in the first and second instruction registers IR1, IR2 are supplied repeatedly to the instruction decoder 1DEC for recurrent execution until a repeat counter RC within the repeat controller 207 returns to zero.

摘要： In a digital-analog hybrid LSI including an analog circuit (2) and a digital circuit (3), the analog circuit (2) includes a circuit for sampling, according to the operation timing of a switch (4), information to be processed by the analog circuit (2) in a capacitor (5). A clock signal generating means (6) generates an operation reference clock signal (b) for the digital circuit (3) so that the change of the clock signal (b) is stopped at a timing when the switch (4) is opened, i.e., during a specified period (T) which includes the high-to-low transition timing of the clock signal. This prevents the analog characteristic of the analog circuit (3) from being degraded by digital noise that is transferred through the junction capacitance of the semiconductor chip (1).
