摘要： A modem and method for operating same. A receiver circuit of the modem is coupled to receive a continuous analog signal from a communication channel. This analog signal includes both packet and idle information. The receiver circuit monitors the analog signal to detect the presence of idle information. Upon detecting idle information, the receiver circuit enters a standby mode in which the processing requirements of the receiver circuit are reduced. A burst mode protocol is also provided, in which packets of digital information are modulated by a transmitter circuit the modem, thereby converting the packets of digital information into analog signal bursts of discrete duration. These analog signal bursts are transmitted from the transmitter circuit to a telephone line. However, the transmitter circuit does not generate any signals between the analog signal bursts. A receiver circuit monitors the telephone line to detect the analog signal bursts. Upon detecting the presence of the analog signal bursts on the telephone line, the receiver circuit demodulates the analog signal bursts using full processing capabilities of the receiver circuit. However, upon detecting the absence of the analog signal bursts on the telephone line, the demodulating function of the receiver circuit is disabled. The burst mode protocol enables multi-drop and multi-cast operation, as well as reducing required DSP resources.

摘要： A memory chip for storage and retrieval of data transmitted as streams of data at sustained peak data transfer rates. The memory chip includes a memory device and an interface capable of achieving high bandwidth throughput. The memory device decodes, arbitrates between, and executes memory access commands, and generates memory access responses. The interface includes a data path, and a number of memory controllers. The interface receives and transmits input and output data streams, and the memory controllers control the flow of the input and output data streams within the memory chip. A packet buffer is coupled between the data path and the memory device. The packet buffer provides for temporary storage of memory access commands, response information, and forwarding data.

摘要： A method of and apparatus for noise reduction for a transceiver transmitting frames over a transmission medium in a frame-based communications network. A transceiver transmit path and a transceiver receive path is provided. A blocking switch is located in the transceiver transmit path, the blocking switch allowing transmit signal propagation when enabled, while preventing both transmit signal propagation and circuit device noise coupling from the transceiver transmit path to the transceiver receive path when the blocking switch is disabled. The blocking switch is disabled when the transceiver transmit path is not transmitting frames over the frame-based communications network.

摘要： A method of and apparatus for optimizing signal transformation from a twisted pair transmission line to a combination transmitter and receiver for a frame-based communications network, the transmitter having a transmit output pair port for transmitting signals onto the frame-based communications network over the twisted pair transmission line, the receiver having a receive input pair port for receiving signals from the frame-based communications network over the twisted pair transmission line. A transformer is coupled between the twisted pair transmission line and each of the transmit output pair port and the receive input pair port. The transformer has a coil across the twisted pair, a transmit coil across the transmit output pair port, and a receive coil across the receive input pair port. A transfer ratio between the transmit coil and the coil across the twisted pair is optimized for transmitting signals. A transfer ratio between the receive coil and the coil across the twisted pair is optimized for receiving signals.

摘要： A digital differential analyzer data synchronizer receives data at a first clock rate and synchronizes the data to a second clock rate. The two clock rates are related by a ratio of two integers, but have a variable phase relationship. The synchronizer places incoming data into a series of registers at the first clock rate. A digital differential analyzer functions to generate a synchronization signal having a frequency proportional to a ratio of the first clock rate and the second clock rate. A multiplexer is utilized for sequentially reading the plurality of registers at a rate corresponding to the frequency of the synchronization signal.
