    • A method of communicating speech comprising time-warping a residual low band speech signal to an expanded or compressed version of the residual low band speech signal, time-warping a high band speech signal to an expanded or compressed version of the high band speech signal, and merging the time-warped low band and high band speech signals to give an entire time-warped speech signal. In the low band, the residual low band speech signal is synthesized after time-warping of the residual low band signal while in the high band, an unwarped high band signal is synthesized before time-warping of the high band speech signal. The method may further comprise classifying speech segments and encoding the speech segments. The encoding of the speech segments may be one of code-excited linear prediction, noise-excited linear prediction or 1/8 frame (silence) coding.
    • 一种传送语音的方法,包括将残余低频带语音信号时间扭曲成残余低频带语音信号的扩展或压缩版本,将高频带语音信号时间扭曲成扩展或压缩的 版本的高频带语音信号,并且合并时间扭曲的低频带和高频带语音信号以给出整个时间扭曲的语音信号。 在低频带中,在残余低频带信号的时间扭曲之后合成残余低频带语音信号,而在高频带中,在高频带语音信号的时间扭曲之前合成未扭曲的高频带信号。 该方法可以进一步包括对语音片段进行分类并对语音片段进行编码。 语音段的编码可以是码激励线性预测,噪声激励线性预测或1/8帧(静音)编码之一。

    • One or more Shadow Register Files (SRF) are interposed between a Physical Register File (PRF) and a Backing Store (BS) in a shadow register file system. The SRFs comprise dual-port registers connected serially in a chain of arbitrary depth from the PRF. A Register Save Engine has random access to one port of the registers in the final SRF in the chain, and saves/restores data between the final SRF and the BS, e.g., RAM. As PRF registers are deallocated from calling procedures for use by called procedures, data are serially shifted from multi-port registers in the PRF through successive corresponding dual-port registers in SRFs, and are serially shifted back toward the multi-port registers as the PRF registers are reallocated to calling procedures. Since no procedure can access more than the number of registers in the PRF, the effective size of the PRF is increased, using less costly dual-port registers.
    • 影子寄存器文件系统中的一个或多个影子寄存器文件(SRF)插入在物理寄存器文件(PRF)和后备存储(BS)之间。 SRF包括串行连接在PRF任意深度链中的双端口寄存器。 一个寄存器保存引擎可随机访问链中最后一个SRF寄存器的一个端口,并在最终SRF和BS之间(例如RAM)保存/恢复数据。 当PRF寄存器从调用过程中释放以供被调用过程使用时,数据通过SRF中的相应双端口寄存器从PRF中的多端口寄存器串行地移位,并且作为PRF被顺序地移回到多端口寄存器 寄存器被重新分配给调用过程。 由于没有任何过程可以访问PRF中的寄存器数量以上,所以使用成本较低的双端口寄存器来增加PRF的有效大小。

    • The invention relates to interpreting the change in the increment of the RTP TS field as occurring either due to silence suppression for a voice flow or a change in sampling/ frame rate of a video flow. By interpreting this change correctly, the value of the TS_STRIDE field in robust header compression may be correctly calculated leading to efficient header compression performance. In one aspect, there is disclosed a method of improving ROHC between an Access Network AN having a compressor and an Access Terminal AT having a decompressor, comprising providing flow information to the compressor relating to a change in the increment of an RTP TS field of a header (302) ; determining the change in the increment of an RTP TS field as occurring either due to silence suppression or due to a change in a sampling/ frame rate (306) ; and taking appropriate action for TS_STRIDE .
