Patent EP-0454364-A2 (EP)
Inventor: DOSHI BHARAT TARACHAND
IPC: H04L12/56
Filed: 1991-04-18
Abstract: A packet transmission protocol, which operates in a full-duplex mode in a system, which includes a transmitter, a receiver, and a communications network having a channel that logically ties the transmitter and the receiver together through the network, is disclosed. The receiver regularly sends a control packet to the transmitter. The control packet includes a plurality of data fields, which are useful in describing the state of the receiver to the transmitter. The transmitter receives the receiver's control packet and analyzes the data. If it finds that a particular block of packets had been received with an error (or not received at all), then the transmitter retransmits the block. 
     The protocol includes two windows for controlling the volume of information, e.g. number of blocks, in the network. The first window (W₁), called the network window, is used to limit the data in the network so that network buffer resources can be sized economically and yet in a manner such that there will not be an excessive loss in the number of packets transmitted through the network. The second window (W₂), called the receiver flow control window, is typically larger than the first window and is used to assure that packets are not dropped, or lost, at the receiver. By having the second window larger than the first window, throughput can be increased while still meeting a commitment to the network that limits the number of packets in the network to a value consistent with economical buffer sizing. Typically, the first window is set to the value of the bandwidth delay product of the channel and the second window is set to a value at least twice that of the first window. The functions related to receiver flow control and network congestion control can be decoupled.

Abstract: An improved variable voltage transition circuit of the type that switches a capacitor (C) between charging and discharging current sources (I1, I2) when an input voltage (Vin) transitions, the capacitor being coupled via respective Schottky diodes (D5, D6) to tracking clamp circuits (16, 18), has a compensation circuit (20, 22) that includes second current sources (I3, I4) that match the charging and discharging current sources and uses regenerative feedback to turn on and off the Schottky diodes virtually instantaneously when the input voltage transitions. A fixed clamp circuit (24, 26) and a bias switch circuit (28, 30) are coupled between the clamp circuits and one side of the transition switch to provide a conductive path for the second current sources that results in a change in the bias of the tracking clamp circuits such that when the input voltage transitions the "on" Schottky diode is instantaneously turned off, and the "off" Schottky diode is turned completely on very quickly after it starts to conduct at the end of the transition.

Abstract: An improved NRZ clock and data recovery system lends itself to integration, includes a NRZ phase detector, an NRZ frequency detector and a lock detector, and provides automatic centering of the clock edge within the bit interval in a manner that is independent of analog delays and process and temperature variations. NRZ data is applied to one side of an exclusive-OR gate (6) and a twice delayed (2, 4) version of the NRZ data is applied to the other side. The output of the XOR gate (6), a "blivet" signal, is applied to a NRZ phase detector (10) comprising two AND gates (12,14), one of which (12) has as its other input a recovered clock signal output of a VCO (20) and the other of which has as its other input an inverted (16) version of the recovered clock signal. The "up" and "down" outputs of the AND gates (10,12) indicate which direction a frequency control signal (26) should change the VCO (20) frequency. A data holding flip-flop (28) whose input is a once delayed (2) version of the NRZ data is clocked with the recovered clock signal. The NRZ frequency detector (50) monitors the state of the recovered clock signal on opposite edges (52,53) of the blivet to detect too-high (56), too low (55) and good (54) conditions. The results of the detection can be ignored if a lock signal indicates that the phase lock loop is locked. The lock detector (30) consists of a saturating up/down counter (42) that is incremented (38) by one when good blivets (32) occur and is decremented (40) by four when not-good blivets (36) occur.

Abstract: In a circuit arrangement for correcting phase errors of P-channel and Q-channel baseband signals of a QPSK signal, input registers are provided corresponding respectively to possible bit patterns which the unique words of the P-channel and Q-channel baseband signals may assume. Each input register stores 2N bits of incoming unique words of the P- and Q-channel signals. Reference registers corresponding to the possible bit patterns are provided for individually storing 2N bits of a corresponding one of the possible bit patterns. Mismatches between the bits stored in each input register and the corresponding reference register are detected and compared with thresholds to produce a phase error correcting signal. In response, the connecting paths of the P- and Q-channel baseband signals to output terminals are controlled and bit reversals are effected on the P- and Q-channel baseband signals.

Abstract: A method is disclosed for accurately obtaining in a short period of time the position and slope of a specific edge line even when there are many extraneous points caused by dust and other such garbage or electrical noise around the edge line to be obtained. A window (W) covering the area containing the desired edge line is set (8), and the area inside the window is scanned (6, 7, 8) at a specific interval in a direction crossing the edge line to obtain specific image data. The coordinates of points indicating a change in brightness in the scanning direction are obtained (9) as edge points. The area inside the window is divided into a group of rectangular subareas (12) parallel to the edge line to be detected and at a predetermined pitch in a size capable of containing the edge line. The subarea containing the greatest number of edge points is obtained (14), and the edge line is then estimated (15, 19) from the coordinates of the edge points in this subarea containing the greatest number of edge points.

Abstract: Each memory (200) cell in an SRAM array contains an auxiliary reading (MR1) transistor connected across one of the transistors (MP1) in each cell. A row read line (RRi) controls the ON-OFF condition of this auxiliary reading transistor. In addition, each cell has two access transistors (MW1,MW2) for connecting the cell to complementary column bit lines (Bj,           B     ¯           j). The ON-OFF condition of both of these access transistors is controlled by a row write line (RWi). Each cell has two power nodes (N3,N4), one connected to a power source such as VDD and the other connected to a column detector line (Dj) that terminates in a current sensor. The state of the memory cell is sensed by this current sensor. In one embodiment, the power line that brings the voltage VDD to the cells is a column line; in another embodiment, it is a row line. Thus there are a total of four column lines and two row lines in the one embodiment, and a total of three column lines and three row lines in the other embodiment.
