摘要： A unique method for chroma vertical upsampling used, for example, for conversion of the “4:2:0” format chroma information used in many applications of digital video, to the “4:2:2” or “4:4:4” format, is presented. This conversion is required so that video encoders can effect the display of this chroma information with a minimum of visible artifacts. The present invention carries out chroma vertical upsampling on a pixel by pixel basis. This chroma vertical upsampling is performed as a function of the amount of motion associated with each pixel as detected between 2 or more fields, and the field, frame and progressive sequence characteristics of the incoming video signal data.

摘要： A technique for determining the slope of a field pixel is described. According to the technique, one or more sets of diagonal field pixels are downscaled (or downsampled) before they are provided to respective edge detector circuits. By downscaling the sets of diagonal field pixels before they are provided to respective detector circuits, the edge detector circuits detect diagonal edges and, in particular, shallow diagonal edges with greater accuracy. As such, the slopes assigned to the field pixels are more likely to be correct. This ultimately results in a high quality progressive video signal that can be used to generate an image that is completely or substantially free from objectionable artifacts.

摘要： A universal asynchronous receiver transmitter (UART) emulation stage for modem communication uses a digital signal processor containing a software UART control program for sending UART control signals to hardware based UART emulation circuitry. The software UART control program communicates to a modem application interface program that is under control of a host processor. The UART emulation circuitry that is responsive to the control signals from the digital signal processor, includes dedicated transmit and receive FIFO buffer memory for storing modem data and also includes interrupt generation logic to generate an interrupt for the digital signal processor when the received FIFO buffer memory is at a predetermined threshold. The UART emulation circuitry also includes programmable control logic for facilitating host processor interrupt pacing to maintain high compatibility with legacy applications, namely DOS based applications.

摘要： Improved 2:2 and 3:2 pull-down detection techniques are presented. These techniques can, for example, be used when converting an interlaced video signal into a progressive video signal. The improved techniques are less susceptible to bad edits. In one embodiment, comparison values are generated using consecutive fields of the interlaced video signal having the same parity, with a sequence of one small comparison value followed four large comparison values, where the four large comparison values include two pairs of similar large comparison values, is used to indicate a 3:2 pull-down.

摘要： A bus interface control system and method includes an on-demand bus master interface for independently requesting multistream data from host memory without interrupting processing of the host processor between independent requests for data packets. A plurality of digital signal processors share the host bus and utilize flexible data speed transfer depending upon demand of real time data that must be transferred from host memory. The master interface control system includes an packet by packet arbitor to facilitate maximum throughput of data on-demand by the plurality of processing unit.
