A computer system includes a main processing unit ( ) coupled to a DSP/memory module ( ). The DSP/memory module ( ) includes semiconductor memory ( ) and digital signal processor circuitry ( ) including one or more digital signal processors ( ). The DSP/memory module ( ) may be placed in standard main memory sockets, such as a SIMM or DIMM sockets, and used as conventional main memory. The memory module can also be used in a smart mode, wherein the digital signal processor ( ) performs operations on data for retrieval by the main processing unit ( ).

System signaling schemes for processor and memory module

A method and system for implementing time scale modification wherein the method includes a Zero Crossing Module (22) for determining zero crossing points in the signal, a Feature Vector Module (24) for generating feature vectors describing the zero crossing points, a Distance Metric Module (26) for generating distance metrics describing local characteristics at the zero crossing points, an Alignment Module (28) for using the feature vectors and distance metrics for aligning and synchronizing the signal in accordance with local similarities and similarity over a selected time interval to generate a time scale modified signal. The present invention also includes a Cross Fade Module (20) for smoothing transitions between successive frames of the resulting time scale modified signal.

Method and system for time scale modification utilizing feature vectors

A Karaoke system scoring method and system (10) is provided based on detecting, for example, frame energy (19 or 19') of the Karaoke singer and the frame energy of the original artist (29 or 29'). The frame energy is quantized (41 and 43) and compared (45) and based on the comparison a score (37) is generated and displayed (15).

Method and system for karaoke scoring

A Karaoke (10) apparatus with autokeying is provided by measuring the average pitch (28) of the singer or user over a predetermined time period, comparing (29) the pitch of the singer or user voice to that of a reference pitch to provide a signal representing mismatch and changing the pitch (31) of the background music to match that of the singer or user.
