| 20090052208 | Apparatus to Extend HDMI Connections over a Single Ethernet CAT Cable - This invention is to use a single standard unshielded or shielded Ethernet CAT cable, such as CAT5, CAT5e, CAT6 and similar cable, to extend original digital video signals over long distances. The Ethernet CAT cable can be installed with the required length easily and terminated in the field with simple tools. The Ethernet cable is the standard communication wiring in modern buildings. On the contrary, HDMI cable must be pre-terminated in the factory and is extremely difficult to install in buildings. HDMI video signals contain three pairs of CML video signals, one pair of high-speed clock signals, and three control signals. Each video signal has a data rate over 1.6 Gbps, and one of the control signals is bi-directional. Sending these signals over a single Ethernet CAT cable is very difficult. This invention presents an apparatus to extend HDMI signals over a single Ethernet CAT cable. The present invention is able to extend 1080p video over more than 150 feet, and to reliably extend 1080i over more than 200 feet with HDCP capability over a single unshielded or shielded Ethernet CAT cable. | 02-26-2009 |

| 20100332804 | UNIFIED HIGH-FREQUENCY OUT-OF-ORDER PICK QUEUE WITH SUPPORT FOR SPECULATIVE INSTRUCTIONS - Systems and methods for efficient picking of instructions for out-of-order issue and execution in a processor. In one embodiment, a processor comprises a unified pick queue that is dynamically allocated. Each entry is configured to store age and dependency information relative to other decoded instructions. Also, each entry stores a picked field, which when asserted indicates the decoded instruction has already been picked for out-of-order issue and execution. When asserted, a trigger field indicates a result of a corresponding decoded instruction will be available a predetermined number of clock cycles afterward. A younger instruction dependent on a result of an older instruction is ready to be picked before the result of the older instruction is available. In this case, the older instruction has asserted picked and trigger fields. | 12-30-2010 |
| 20100332806 | DEPENDENCY MATRIX FOR THE DETERMINATION OF LOAD DEPENDENCIES - Systems and methods for identification of dependent instructions on speculative load operations in a processor. A processor allocates entries of a unified pick queue for decoded and renamed instructions. Each entry of a corresponding dependency matrix is configured to store a dependency bit for each other instruction in the pick queue. The processor speculates that loads will hit in the data cache, hit in the TLB and not have a read after write (RAW) hazard. For each unresolved load, the pick queue tracks dependent instructions via dependency vectors based upon the dependency matrix. If a load speculation is found to be incorrect, dependent instructions in the pick queue are reset to allow for subsequent picking, and dependent instructions in flight are canceled. On completion of a load miss, dependent operations are re-issued. On resolution of a TLB miss or RAW hazard, the original load is replayed and dependent operations are issued again from the pick queue. | 12-30-2010 |
