International Classification:

G06F 1212

US Classification:

711155, 711 5, 711141, 714752

Abstract:

An apparatus and method for performing speculative directory cache tag updates for read accesses to memory is herein disclosed. A control unit for performing tag updates is coupled between the memory controller and the memory bank in a multiprocessor system that employs a directory-based coherency protocol. The control unit transmits data read from the memory bank to the memory controller while calculating the updated tag that it then writes back to the memory bank. In this manner, the memory bank busy time and memory bus traffic are reduced thereby improving the overall performance of a memory access.

International Classification:

US Classification:

370394, 370401, 370414, 370428

Abstract:

Hardware interconnected around multiple packet forwarding engines prepends sequence numbers to packets going into multiple forwarding engines through parallel paths, After processing by the multiple forwarding engines, packets are reordered using queues and a packet ordering mechanism, such that the sequence numbers are put back into their original prepended order. Exception packets flowing through the forwarding engines do not follow a conventional fast path, but are processed off-line and emerge from the forwarding engines out of order relative to fast path packets. These exception packets are marked, such that after they exit the forwarding engines, they are ordered among themselves independent of conventional fast path packets. Viewed externally, all exception packets are ordered across all multiple forwarding engines independent of the fast path packets.

G06F 13/00
G06F 13/28

US Classification:

711160, 711105

Abstract:

In an embodiment, a memory scheduler is provided to process memory requests. The memory scheduler may comprise: a plurality of arbitrators that each select memory requests according to age of the memory requests and whether resources are available for the memory requests; and a second-level arbitrator that selects, for an arbitration round, a series of memory requests made available by the plurality of arbitrators, wherein the second-level arbitrator begins the arbitration round by selecting a memory request from a least recently used (LRU) arbitrator of the plurality of arbitrators.

International Classification:

H04N 5/46

US Classification:

348556, 348555

Abstract:

A method and apparatus are disclosed that automatically switch between displaying local standard definition television content and non-local, high definition television content. When the same television content is available for display in both standard and high definition formats, the television converter device preferentially displays the high definition format.

International Classification:

H04N 7/16

US Classification:

725153, 725 59

Abstract:

The present invention provides a method and device that can easily configure an entertainment system automatically or semi-automatically. The reconfiguration of the entertainment system can be achieved by cycling through the possible configurations of the entertainment system (i. e. different combinations of operational states of the components that make up the entertainment system) by changing various operational states of certain components until an operable configuration is found. The invention may be implemented in any component of the entertainment system including a set-top-box, satellite receiver or a remote control.

Abstract:

A remote control and method of programming a remote control for controlling components in an entertainment system are disclosed. The remote control may operate in multiple modes including a limited mode that prevents the remote control from sending predetermined commands to one or more components, even when instructed to do so by the user. In addition, the remote control may issue one or more commands to each component in response to a single user input.
