Abstract: The disclosure includes a method for rapidly recovering the speed of TCP transmission after a cross technology handover experienced by a mobile device. In the method, the mobile device receives a sequentially first TCP data packet after the cross technology handover completes via a TCP session between the mobile device and a remote TCP server, generates a first acknowledgement (ACK) associated with the sequentially first TCP data packet, where the first ACK comprises a first Selective ACK (SACK) option, removes the first SACK option from the first ACK when a gap exists between data in the sequentially first TCP data packet and data received before the cross technology handover occurs, and sends the first ACK without the first SACK option to the remote TCP server via the TCP session. Because the ACK is without the SACK option when the gap exists, the speed of TCP transmission will be recovered rapidly.

The data request message includes at least a name of targeted data, a name of low-level data, and a semantic mashup logic for generating the targeted data using the low-level data. In response to determining that the targeted data is not stored at the router and that the low-level data is stored at the router, the router generates the targeted data using the low-level data based on the semantic mashup logic. The router also generates a data response message. The data response message includes the generated targeted data.

Abstract: It is possible to reduce the latency attributable to memory protection in shared memory systems by performing access protection at a central Data Ownership Manager (DOM), rather than at distributed memory management units in the central processing unit (CPU) elements (CEs) responsible for parallel thread processing. In particular, the DOM may monitor read requests communicated over a data plane between the CEs and a memory controller, and perform access protection verification in parallel with the memory controller's generation of the data response. The DOM may be separate and distinct from both the CEs and the memory controller, and therefore may generally be able to make the access determination without interfering with data plane processing/generation of the read requests and data responses exchanged between the memory controller and the CEs.

Abstract: Branch prediction techniques are described that can improve the performance of pipelined microprocessors. A microprocessor with a hierarchical branch prediction structure is presented. The hierarchy of branch predictors includes: a multi-cycle predictor that provides very accurate branch predictions, but with a latency of multiple cycles; a small and simple branch predictor that can provide branch predictions for a sub-set of instructions with zero-cycle latency; and a fast, intermediate level branch predictor that provides relatively accurate branch prediction, while still having a low, but non-zero instruction prediction latency of only one cycle, for example. To improve operation, the higher accuracy, higher latency branch direction predictor and the fast, lower latency branch direction predictor can share a common target predictor.

Abstract: A thread on a processor core executes one or more instructions to write file data for a file into a persistent memory save area. The instructions to write the file data have the effect of storing the file data for the file in the cache associated with the processor core. The thread running on the processor core flushes the file data from the cache to the persistent memory save area while retaining the file data in the cache. The thread running on the processor core copies the file data from the cache for the processor core into a persistent copy of the file that is stored in persistent memory.
