    • An instruction execution pipeline for use in a data processor. The instruction execution pipeline comprises: 1) an instruction fetch stage; 2) a decode stage; 3) an execution stage; and 4) a write-back stage. The instruction pipeline repetitively executes a loop of instructions by fetching and decoding a first instruction associated with the loop during a first iteration of the loop, storing first decoded instruction information associated with the first instruction during the first iteration of the loop, and using the stored first decoded instruction information during at least a second iteration of the loop without further fetching and decoding of the first instruction during the at least a second iteration of the loop.

    • A method and a system for obtaining path information as well as a PCE are disclosed herein. All the PCEs from the source PCE to the confluent PCE compute the shortest path from the source node to the egress border node of the domain covered by the respective PCE one by one, and send the computation result to the next-hop PCE until the confluent PCE. Meanwhile, all the PCEs from the destination PCE to the confluent PCE compute the shortest path from the destination node to the ingress border node of the domain covered by the respective PCE one by one, and send the computation result to the previous-hop PCE until the confluent PCE. After receiving computation results from the previous-hop PCE and the next-hop PCE, the confluent PCE computes the shortest path between the source node and the destination node, and sends the shortest path to the source PCE.

    • High compression rate codecs in gateways servicing Voice-over-Internet Protocol (VoIP) and Voice Band Data (VBD) calls distort modem/fax Answer Back Tones (e.g., 2100 Hz), which may lead to signal distortion and call hang-ups. To prevent such occurrences, a method or corresponding apparatus forces originating and terminating gateways to stay in a low complexity non-voice compression codec (e.g., ITU G.711) after prenegotiating a high complexity, voice compression codec (e.g., G.729 or G.726) during a short beginning period of a voice call. The low complexity codec avoids distorted answer back tone leakage associated with previous solutions that use a notch filter to block the leakage, thereby significantly improving the success rate of a VBD call by completely eliminating modem answer back tone distortion caused by high complexity codecs that use voice compression and by completely eliminating use of the notch filter.
    • 通过互联网语音协议(VoIP)和语音频带数据(VBD)的网关中的高压缩率编解码器调用可能导致信号失真和呼叫挂断的调制解调器/传真回答音(例如,2100 Hz)。 为了防止这种情况发生,在预先谈判高复杂度的语音压缩编解码器(例如G.729或者G.711)之后,方法或相应的装置强制发起和终止网关停留在低复杂度的非语音压缩编解码器(例如,ITU G.711) G.726)在语音通话的短的开始阶段。 低复杂度编解码器避免了与使用陷波滤波器阻止泄漏的以前解决方案相关的失真回答音泄漏,从而通过完全消除由使用语音的高复杂度编解码器引起的调制解调器应答回音失真,从而显着提高了VBD呼叫的成功率 并通过完全消除陷波滤波器的使用。
