摘要： PURPOSE: To mix an animation sequence with computer graphics to simultaneously display them by mixing the animation sequence stored in a compressed form with computer graphics and synchronizing the animation sequence released from compression with computer graphics. CONSTITUTION: A CO-ROM drive 26 supplies compressed data indicating the animation sequence to an animation sequence generator 20. This generator 20 reads a block of compressed picture elements from a specific frame from a clutch pad memory 44 and releases them from compression to obtain individual digital picture elements and sends them to a single line store 36 and synchronizes them with graphic picture information there. A control logic 40 selects the operation of a digital mixer 34 through a control bus. The output of the digital mixer 34 where the animation sequence and graphics are mixed is sent to a video DAC 42, and analog R, G, and B signals to be sent to a computer monitor 22 are generated there.

摘要： Extended sleep in a wireless device. In an embodiment, synchronized parameters, used by a wireless device to define an extended-sleep cycle, are stored at a system. Based on the synchronized parameters, the system determines a transmission time at which to transmit a message over the wireless communication network such that the message will be received by the wireless device during a portion of the extended-sleep cycle during which the wireless device is monitoring paging occasions. The message is then queued until it is transmitted at the transmission time.

摘要： A method and system for capturing live video signal data using bufferless data compression are disclosed. Live video signal data is vertically scaled. A 4:2:2 to 4:2:0 color format conversion is performed simultaneous with the vertical scaling step. A one-dimensional bufferless discrete cosine transform is performed on the scaled live video signal data to create a plurality of scaled DCT coefficients. Each of the plurality of scaled DCT coefficients is then Huffman coded. Each of the Huffman encoded DCT coefficients may then be sent via a USB interface to a USB bus.

摘要： Preventing peak current draw in a wireless device. In an embodiment, a data payload to be transmitted is segmented into data payload segment(s) based on the data payload size and a peak current rating of the wireless device's battery, such that each data payload segment has a segment size which is estimated to result, during transmission of the data payload segment, in a maximum current draw from the battery that is less than the peak current rating of the battery. Then, each data payload segment is transmitted, such that the transmission of one data payload segment does not overlap with the transmission of any other data payload segment.

摘要： A method and system for coupling a coprocessor (220) to a master device, in which the coprocessor (220) emulates a memory interface to the master device, like that of a memory device. The coprocessor (220) is coupled to a memory bus (212) and receives memory accesses directed to a set of addresses not covered by memory devices also coupled to the memory bus (212). The coprocessor (220) is disposed to receive data written from the master device, perform a function on that data, and respond to a read data command from the master device with processing results. The coprocessor (220) uses memory block transfers to read data from and write data to memory devices also coupled to the memory bus (212). The coprocessor (220) is adapted to compute, in response to data written to it by the graphics processor, a graphical function such as 3D processing function, MPEG video compression or decompression, a raytracing function, or some related function in support of graphics processing. The coprocessor (220) may communicate with the central processor (201) and its memory (202) using a memory access operation performed by the central processor (201), and may communicate with the graphics memory (211) using a memory block transfer performed by the graphics processor (210).
