摘要： The present invention discloses circuits for isolating and attenuating signals generated by a telephone network. In disclosed embodiments, a metering pulse signal is isolated from the terminals of the connecting device, and then attenuated with an impedance that is synthesized with a programmable digital signal processor. Embodiments also utilize the digital signal processor to synthesize a termination impedance for the connecting device. The termination impedance matches closely the characteristic impedance of the network, so as to minimize wave reflections and the like.

摘要： An improved architecture for efficiently calculating a discrete wavelet transform is presented. The present system appreciates the associated redundancies of calculations and proposes a topology for eliminating such redundant calculations through the use of storing and making such previously calculated coefficients available in successive wavelet coefficient calculations. The present system while recognizing redundant calculations and performing storage operations, also provides a pipelined architecture whereby the wavelet coefficients are calculated and combined for use in a wavelet packet tree architecture.

摘要： The high throughput UART to DSP interface (UDIF) maintains UART functionality while integrating dual Transmit (Tx) and Receive (Rx) FIFO buffers that are optimized for more efficient interaction with their respective I/O processors. The portion of the interface design interacting with the DSP, the UDIF, provides several unique Status, Informational, and Control registers that lower the DSP overhead required for many of the basic modem functions. The UDIF design also performs parity add, parity strip, and character echo functions, traditionally performed at a high overhead cost by the DSP. These functions are more efficiently preformed by hardware implementations than by the software routines executed by the DSP. More burdensome command functions like escape, AT, and flow control commands can also be implemented through hardware implementations to reduce processor overhead.
摘要翻译：高吞吐量UART到DSP接口（UDIF）在集成双发送（Tx）和接收（Rx））FIFO缓冲器时保持UART功能，该缓冲器经过优化，可与各自的I / O处理器进行更有效的交互。接口设计与DSP（UDIF）交互的部分提供了几种独特的状态，信息和控制寄存器，可以降低许多基本调制解调器功能所需的DSP开销。 UDIF设计还执行奇偶校验位，奇偶校验位和字符回波功能，传统上由DSP以高额外的成本执行。这些功能通过硬件实现更有效地执行，而不是由DSP执行的软件程序执行。还可以通过硬件实现来实现更加繁重的命令功能，如转义，AT和流控制命令，以减少处理器开销。

摘要： The present invention provides apparatus and methods for attenuating signals received from a source over a data transmission line, having an unknown resistance, to achieve optimized signals in various data terminal and data communications equipment. In a preferred embodiment, a resistor network is operably coupled between the transmission line and a means for processing the signal, such as a digital processor, an ADC and a DAC. The resistor network comprises a termination resistor that is associated with a termination voltage, a variable resistor and another resistor. During use, a switch is operably positioned between a plurality of switch positions so that two voltage measurements will lead to the determination of the voltage of the source and the termination voltage within the resistor network. Once these voltages are known, the unknown resistance can be estimated. Thereafter, the length of the transmission line may be determined because of known resistance-per-unit-distance characteristics of the transmission line. In response to knowing this length, the digital processor selects a desired resistance value for the variable resistor so that, upon adjustment of the variable resistor by the DAC, the signal becomes a largest-possible input at the ADC.
