Transmission circuit, reception circuit, transmission method, reception method, communication system and communication method therefor
In transmission of channel-coded serial data, early establishment of symbol synchronization between a transmitter and a receiver is achieved while reducing coding loss in transmission of valid data. In an idle period for not transmitting the valid data, a transmitting circuit selects first channel coding (e.g. 8B/10B coding) enabling early establishment of synchronization and transmits a synchronization symbol encoded using the first channel coding. In response to this, a receiving circuit establishes and maintains symbol synchronization. When the valid data is transmitted, the transmitting circuit transmits a symbol indicating a packet start position, selects second channel coding (e.g. 64B/66B coding) having less coding loss than the first channel coding, and transmits the valid data encoded using the second channel coding. Upon reception of the symbol indicating the packet start position, the receiving circuit switches to reception using the second channel coding and receives the valid data. |

To guarantee quality of service (QoS) with low complexity, the adjustment first reserves some slots for each port pair in each frame, then releases surplus allocations and supplements deficit allocations according to a dichotomy order, designed for high throughput, low jitter, fairness, and low computational complexity. |

Ring-of-clusters network topologies
In a ring-of-clusters network topology, groups of slave devices are accessed in parallel, such that the latency around the ring is proportional to the number of clusters and not proportional to the number of integrated circuits. The devices of a cluster share input and output ring segments such that packets arriving on the input segment are received and interpreted by all the devices in a cluster. In other embodiments, none, some or all but one slaves per cluster are asleep or otherwise disabled so that they do not input and interpret incoming packets. Regardless, in all embodiments, the slaves of a cluster cooperate, potentially under the controller's direction, to ensure that at most one of them is actively driving the output segment at any given time. The devices may be addressed through a device ID, a cluster ID, or a combination thereof. Embodiments of the invention are suited to exploit multi-chip module implementations and forms of vertical circuit stacking. |

Recursive lookup with a hardware trie structure that has no sequential logic elements
A hardware trie structure includes a tree of internal node circuits and leaf node circuits. Each internal node is configured by a corresponding multi-bit node control value (NCV). Each leaf node can output a corresponding result value (RV). An input value (IV) supplied onto input leads of the trie causes signals to propagate through the trie such that one of the leaf nodes outputs one of the RVs onto output leads of the trie. In a transactional memory, a memory stores a set of NCVs and RVs. In response to a lookup command, the NCVs and RVs are read out of memory and are used to configure the trie. The IV of the lookup is supplied to the input leads, and the trie looks up an RV. A non-final RV initiates another lookup in a recursive fashion, whereas a final RV is returned as the result of the lookup command. |

The hysteresis values can be selected based on a type of the current cell or related access point to expand the coverage area where desired. Thus, where the current access point is favorable, a larger hysteresis can be added to measurements related to the current access point. |

Method and apparatus for cross-talk cancellation
The present invention addresses the problem of a second (or higher) order representation of a transmit signal which is transmitted by a transceiver being mixed into the region of the frequency spectrum of interest to the transceiver receiver, such that it can not then be spectrally filtered out. At its most straightforward, in one embodiment of the invention this is achieved by providing a cross-talk cancellation unit which takes the transmit signal, and obtains the second (or higher) order representation thereof. This representation is then subtracted from the received signal before the signal is passed to the radio control receiver signal processing elements. However, in a more preferred arrangement a filter is also provided, to filter the second or higher order version of the transmit signal, prior to its being subtracted from the received signal. The filter basically takes out the effects of any other filtering or processing which has happened to the transmit signal in the receiver signal chain. This would be, for example, the filtering effects provided by the anti-aliasing filter in the receiver. |

Memory array with self-aligned epitaxially grown memory elements and annular FET
A system and method for fabricating a memory array device. An example memory array device includes a plurality of memory cells, each including a FET over a substrate and a memory element over the FET. Each memory element includes a plurality of epitaxially grown memory element layers. The memory array device includes a plurality of gate conductors configured a first axis, in parallel. Each gate conductor laterally surrounds a plurality of FETs of the memory cells along the first axis. The memory array device includes a plurality of bit lines configured along a second axis, in parallel, and electrically coupled to a plurality of memory elements along the second axis. Embodiments of the memory array preserve alignment of crystal lattices beginning from the bottom layers in the FET up to the top active layers in memory element, thus preserving crystal lattice alignment between transistor and memory element. |

Apparatus for protecting EUV optical elements
Apparatus having a chamber with an interior wall and a region within the chamber from which a contaminating material emanates when the apparatus is in operation. A plurality of vanes is positioned on a portion of the interior wall, each of the vanes having a first surface which is oriented along a direction between the vane and the region and a second surface adjacent the first surface which is oriented to deflect the contaminating material striking the second surface away from the region, the second surfaces being dimensioned and juxtaposed with respect to one another such that the second surfaces substantially prevent the contaminating material from striking the portion of the interior wall. At least part of each of the vanes may be covered with a mesh. The vanes may be heated, and may be heated at least to a melting point of the contaminating material. The apparatus is especially applicable to protecting multilayer mirrors serving as collectors in systems for generating EUV light for use in semiconductor photolithography. |
