Title: Memory management
Inventor: JASON PARKER
IPC: G06F12/14
Filed: 2016-12-09
Abstract: Address translation carried out in a device comprising input circuitry to receive an input memory address within an input memory address space, such as virtual memory, permission circuitry to determine whether memory access is permitted for the input memory address wherein there is a permission data store with dedicated entries for each of a set of memory regions wherein each input memory address maps to a memory region and output circuitry to provide an output memory address as a predetermined function of the input memory address if the permission circuitry indicates that memory access is allowed. There may be a second translation circuit which outputs an output memory address when the permission circuitry indicates memory access is not permitted. The second translation circuit may perform address translation with reference to address translation tables and have a translation look aside buffer to store translations of a subset of input memory addresses in an input memory space.

Title: Enhancing curves using non-uniformly scaled cubic variation of curvature curves
Inventor: Stephen Schiller
IPC: G06T7/68
Filed: 2017-01-20
Abstract: A method and system of generating enhanced curves that are aesthetically pleasing. The method comprises steps of detecting a user input defining points of a spline; non-uniformly scaling a curve in the spline in a single direction; detecting end point constraints from the non-uniformly scaled curve; computing multiple cubic variation of curvature (CVC) curves corresponding the detected end point constraints; and downscaling the CVC curves while maintaining the end point constraints to generate an enhanced curve in the spline. Preferably, a canonical coordinate system is used and the curve is rotated such that an end point of the curve is at a first unit along the horizontal axis of the canonical system (fig.2b) and the scaling in the single direction is based on the vertical value of the canonical system. Preferably the curve has a set of interpolated control points and CVC curves comprise curve primitives of the input curve to construct the CVC curve between the set of interpolated points.

Title: Method and apparatus for transmitting signals over wire connections
Inventor: ANAS AL RAWI
IPC: H04L25/03
Filed: 2017-03-31
Abstract: A method and apparatus to transmit data over different channels from a transmitter 16, such as a DSLAM, to one or more receivers 51-53, each of which is connected via a respective wire connection 21-23. For each channel: (i) determine a value that is a function of a power mask, (ii) determine a value that is a function of an upper bound for a channel capacity, (iii) apply a third function to the values previously obtained at (i) and (ii) to determine a value for the transmission power of the channel. The function of (i) may additionally be a function of the ratio of the power coupling coefficient to a noise level on the channel. The method may be used for DSL configurations that utilise direct transmission channels over twisted metallic pairs (TMP) and indirect phantom channels that use different combinations of TMPs. The method provides a fast converging water-filling algorithm for performing equalisation on the communication channels. Transmission of data is optimised and the power budget matched to channel behaviours.

Title: Realm identifier comparison for translation cache lookup
Inventor: MATTHEW LUCIEN EVANS
IPC: G06F12/14
Filed: 2017-06-28
Abstract: A data processing system has a translation cache or translation look-aside buffer (TLB) 100 to store translations from virtual memory addresses to physical memory addresses. Each entry includes a translation context identifier 254 and a realm identifier 270. The translation context identifier may be virtual machine identifier 250 and an address space identifier 252. The realm corresponds to at least a portion of a process. When the system looks up a virtual memory address in the cache, the realm identifier and translation context identifier in the memory access request are compared with those in the translation cache entries. If both identifiers and the virtual memory address tag 262 match those in the entry, a match is found. In addition, if there is no match, a translation for the requested address is not added to the cache if the requesting realm is not permitted to access the address. The realm may also be matched if a visibility attribute indicates that the requesting realm is allowed to access the translation entry.

Title: Improved contention mechanism for access to random resource units in an 802.11 Channel
Inventor: Stéphane Baron
IPC: H04W74/08
Filed: 2016-02-29
Abstract: In an 802.11ax network with an access point, a trigger frame offers random resource units to nodes for data uplink communication to the access point. To dynamically adapt the contention mechanism used by the nodes to access the random resource units, the AP updates a correcting TBD parameter at each new TXOP and includes the updated adjusting parameter in the trigger frame for the next TXOP. The nodes use the TBD parameter to generate a local random RU backoff value from a contention window range, for contending for access to the random resource units. The TBD parameter may directly impact the contention window size CWO or boundaries values of a selection range from which CWO is selected. The backoff value may be re-decided after the successful transmission of data to the access point. Further, the backoff value may be re-decided after a failed attempt to transmit data to the access point using a different method to when the transmission is successful.
