Patent application numberDescriptionPublished
20090037626Multi-drop bus system - A multi-drop bus system and a method for operating such a system. The system includes a multi-drop bus having at least one bus line, each bus line being made up of a multiple of line segments. Each of the line segments terminates at a drop point and each drop point is coupled to a load impedance. The characteristic impedance of a line segment is matched to the equivalent impedance presented by the load impedance in combination with the characteristic impedance of a following segment, or is matched to the load impedance if there is no following segment.02-05-2009
20090059642Memory Controller With Multi-Modal Reference Pad - A memory controller operates in two modes to support different types of memory devices. In a first mode, the memory controller distributes a dedicated reference voltage with each of a plurality of signal bundles to a corresponding plurality of memory devices. The reference voltages are conveyed using pads that are alternatively used for e.g. timing-reference signals in a second mode, so the provision for bundle-specific reference voltages need not increase the number of pads on the memory controller.03-05-2009
20090089557UTILIZING MASKED DATA BITS DURING ACCESSES TO A MEMORY - Embodiments of an apparatus that uses unused masked data bits during an access to a memory are described. This apparatus includes a selection circuit, which selects data bits to be driven on data lines during the access to the memory. This selection circuit includes a control input that receives a data mask signal, which indicates whether a set of data bits is to be masked during the access to the memory. During the access to the memory, the selection circuit selects either the set of data bits to be driven when the data mask signal is not asserted, or an alternative set of values to be driven when the data mask signal is asserted.04-02-2009
20100309964ASYMMETRIC COMMUNICATION ON SHARED LINKS - Embodiments of a system that communicates bidirectional data between two devices via shared links is described. In this system, data is transmitted on the shared links by one of the devices using single-ended drivers, and corresponding symbols are received on the shared links by the other device using differential comparison circuits. The data may be encoded as a series of parallel codewords prior to transmission. Each shared link may communicate a respective symbol in each codeword, which can have one of two possible logical values (e.g., a logic 0 or a logic 1). The corresponding symbols received by the other device may comprise a parallel symbol set, and each of the differential comparison circuits may compare symbols received on pairs of the shared links. A decoder in the other device may decode a respective parallel symbol set from the outputs of the differential comparison circuits to recover the encoded data.12-09-2010
20110025374Multi-Drop Bus System - A multi-drop bus system and a method for operating such a system. The system includes a multi-drop bus having at least one bus line, each bus line being made up of a multiple of line segments. Each of the line segments terminates at a drop point and each drop point is coupled to a load impedance. The characteristic impedance of a line segment is matched to the equivalent impedance presented by the load impedance in combination with the characteristic impedance of a following segment, or is matched to the load impedance if there is no following segment.02-03-2011
20110051854ERROR DETECTION AND OFFSET CANCELLATION DURING MULTI-WIRE COMMUNICATION - Embodiments of a circuit are described. In this circuit, a receive circuit includes M input nodes that receive a set of M symbols on M links during a time interval, where the set of M symbols are associated with a codeword. Moreover, the receive circuit includes a decoder, coupled to the M input nodes, that determines the codeword in a code space based on the set of M symbols and that decodes the codeword to a corresponding set of N decoded symbols. Additionally, the receive circuit may include a detector that detects an imbalance in a number of instances of a first value in the set of M symbols, and a number of instances of a second value in the set of M symbols, and, if an imbalance is detected, that asserts an error condition.03-03-2011
20110084737FREQUENCY RESPONSIVE BUS CODING - A data system permits bus encoding based on frequency of the bus and the frequency of switching on the bus so as to avoid undesirable frequency conditions such as a resonant condition or interference with other electrical devices. Transmission frequencies along one or more busses are monitored and used to control the encoding process, for example, an encoding process based on data bus inversion (DBI). The use of both a measure of an absolute number of logic levels (“DBI_DC”) and a measure of a number of logic level transitions relative to a prior signal (“DBI_AC”) provides a measure of control that may be used to compensate for both main and predriver switching noise.04-14-2011
20110102043REDUCING POWER-SUPPLY-INDUCED JITTER IN A CLOCK-DISTRIBUTION CIRCUIT - A system for compensating for power-supply-induced jitter (PSIJ) in a chain of clock buffers within an integrated circuit is described. During operation, the system couples a first supply voltage from a first voltage source to a supply node of each clock buffer in a first chain of clock buffers. Note that a change in the first supply voltage causes a change in a first propagation delay associated with the first chain of the clock buffers. The system also couples a second chain of clock buffers in series with the first chain of clock buffers. The system then couples the first voltage source to each clock buffer in the second chain of clock buffers through coupling circuitry. Next, the system adjusts the coupling circuitry so that the change in the first supply voltage from the first voltage source causes a change in a second propagation delay associated with the second chain of the clock buffers, wherein the change in the first propagation delay and the change in the second propagation delay are complementary.05-05-2011

20090268491POWER CONVERTER WITH RETRACTABLE CABLE SYSTEM - A modular power converter including a first housing enclosing a converter circuit, and a selectively detachable second housing enclosing a retracting power cable. In a first orientation, the detachable second housing is secured to the first housing to form a unitary housing. In a second orientation, the second housing is detached from the first housing such that a first end of the extended power cable may tether to the first housing output a selectable distance therefrom. The cable also has a second end extendable from the second housing a predetermined distance. This modular power converter forms a single compact device when the power cable is not extended from the second housing.10-29-2009

20090276742AUTOMATING POWER DOMAINS IN ELECTRONIC DESIGN AUTOMATION - One or more portions of the design (e.g., components, channels, or portions thereof) can be assigned instances of one or more component power domains (CPDs). Assigning an instance of a CPD to a design element (or to a portion thereof) can indicate, for example, whether the element can be switched on and off, or whether the element can operate over a range of voltages. The CPD instances can, in turn, be assigned to one or more design power domains (DPDs). Assignments of a CPD to a DPD can be evaluated according to a set of compatibility rules. Two or more electronic design elements can be connected by one or more signal paths. Organizing the CPD instances into DPDs can aid in finding signal paths that cross from a first DPD to a second DPD. To improve the reliability of signal paths traversing a DPD boundary, one or more power domain interface (PDI) components can be created to handle the signal paths at the boundary.11-05-2009
