Abstract: A system and method of recovering from errors in a data processing system. The data processing system includes one or more processor cores coupled to one or more memory controllers. The one or more memory controllers include at least a first memory interface coupled to a first memory and at least a second memory interface coupled to a second memory. In response to determining an error has been detected in the first memory, access to the first memory via the first memory interface is inhibited.

The plurality of memory devices is arranged into symbol slices and each symbol slice is configured to be part of a single error correction code packet. Each command bus of the plurality of command buses is configured to interface between the command register and each memory device in a particular symbol slice. A method of command bus redundancy comprising: configuring a plurality of memory devices into symbol slices, each symbol slice configured to be part of a single error correction code packet; establishing a plurality of command buses, each command bus configured to interface with each memory device in a particular symbol slice; and configuring a command register with sufficient command bus drivers to support each command bus of the plurality of command buses.

Abstract: A phase detector for use in conjunction with a delay locked loop is provided. Programmable delay elements insert an adjustable delay in a received data stream. The programmable delays stress the setup and hold times of the incoming data. Phase detector sampling logic detects the phase difference between a nominal center of the data window, and the limits on the setup (early) edge of the data value window, and the hold time limit (late time) edge of the data valid window (“guardbands”). A data signal arriving earlier than an early guardband or later than a late guardband may not be correctly sampled, and a guardband failure may be said to have occurred. A state machine detects such guardband errors and provides corrective feedback signals.

Abstract: An elastic interface apparatus and method are implemented. The elastic interface includes a plurality of storage units for storing for storing a stream of data values, wherein each storage unit sequentially stores members of respective sets of data values. Each data value is stored for a predetermined number of periods of a local clock. Selection circuitry may be coupled to the storage units to select the respective data value from the data stream for storage in the corresponding storage unit. Data is sequentially output from each storage unit in synchrony with the local clock on a target cycle of the local clock.

Abstract: An apparatus and method for a dynamic wave-pipelined interface are implemented. Data signals received from a sending circuit delayed via a programmable delay device corresponding to each signal before being latched into the receiving device. The programmable delay in each delay device is set according to an initialization procedure whereby each signal is deskewed to a latest arriving signal. Additionally, a phase of an input/output (I/O) clock controlling the latching of the data signals is adjusted so that a latching transition is substantially centered in a data valid window.

Abstract: A method and apparatus are disclosed for communicating between a master and slave device. A sequence of data sets and a clock signal (“Bus clock”) are sent from the master to the slave, wherein the successive sets are asserted by the master at a certain frequency, each set being asserted for a certain time interval. The data and Bus clock are received by the slave, including capturing the data by the slave, responsive to the received Bus clock. The slave generates, from the received Bus clock, a clock (“Local clock”) for clocking operations on the slave. The sequence of the received data sets is held in a sequence of latches in the slave, each set being held for a time interval that is longer than the certain time interval for which the set was asserted by the master.

Abstract: A method and system for increasing speeds of transferring data in a data transfer system which includes a data source and data sink. Both the data source and data sink include clocks which are synchronized to a common clock frequency. A buffer is provided at the data sink and this buffer is utilized to received data from the data source. A control circuit is provided at the data sink and this control circuit receives a bus clock signal from the data source. An N segment dynamic shift register is provided within the data sink which includes at least two segments. A selectable shift control is provided for passing the data through an M segment subset of the N segment shift register, where M is less than N. Additionally, the length of the M segment subset is determined by the phase of a clock within the data sink at the time which the bus clock signal from the data source is received at the data sink.

Abstract: An automated method for designing a signal distribution network in an integrated circuit confines the circuits relating to a particular signal, such as a clock signal, to multiple areas equally distributed over the integrated circuit. Each of the multiple areas have tightly-coupled logic connected to a root driver circuit in which the root driver circuit is connected to the signal input. Within the areas of tightly-coupled logic, user-defined placement circuits or groups such as a programmable clock delay having gates, delays, and splitters are connected to the root driver circuit in accordance with wire capacitance targets and input pin load balancing among all the multiple areas. The input pin load balancing and the wire capacitance targets of the user-defined placement groups connected to the root driver circuit in one of the multiple areas matches the input pin load balancing and the wire capacitance targets of other groups connected to other root driver circuits in other multiple areas.

Abstract: A sewing machine for attaching tapes to a web includes a web feed station, a sewing station and a transfer mechanism to transfer the web from the sewing station to a collection zone. The sewing station includes a sewing head that moves across the web to sew the tape. The tape has hooks periodically spaced along the tape and movement of the sewing head is initiated by sensing one of the hooks at a predetermined locator. Successive tapes may then be sewn with the hooks aligned.
