摘要： A method for dynamically changing a buffer threshold in a tape drive, according to another embodiment, includes monitoring a history of sizes of data transactions between sync commands, the data transactions being from a host to a tape drive, determining that a next sync command is expected to be received relatively sooner or relatively later based on the history of data size transactions, writing buffered data to a magnetic recording tape in response to determining that the next sync command will be received relatively sooner, and increasing a buffer threshold for delaying writing to the magnetic recording tape in response to determining that the next sync command will be received relatively later. A computer program product according to one embodiment includes a computer readable storage medium having program code embodied therewith, the program code readable/executable by a processor to perform the foregoing method.

摘要： According to one embodiment, a method for dynamically changing a buffer threshold in a tape drive includes determining that a drive buffer is emptied of data, calculating a write size indicating an amount of data from a transaction size left to be written to a tape prior to a next anticipated sync command, setting a buffer threshold that triggers a back hitch to a smaller value when the transaction size is less than a buffer size, setting the buffer threshold to the smaller value when an absolute difference between the transaction size and the write size is greater than or equal to the buffer size, and setting the buffer threshold to a larger value when the transaction size is not less than the buffer size and/or the absolute difference between the transaction size and the write size is less than the buffer size.

摘要： Method and apparatus for data storage using data compression techniques. In some embodiments, a data recording medium has a recording surface with a plurality of concentric tracks accessible using a moveable data read/write transducer. A cache memory temporarily stores data during transfer operations with the data recording medium. A controller is configured to, responsive to receipt of input write data, retrieve from the data recording medium to the cache memory a selected multi-block data set associated with the input write data, use the received input data to update the retrieved multi-block data set, compress the updated retrieved multi-block data set to generate a compressed data set, and write the compressed data set to a selected band of adjacent tracks on the data recording surface. A portion of the compressed data set is generated during movement of the data read/write transducer to the selected band of adjacent tracks.

摘要： A digital decoder for television receiver, comprises an input (E) for receiving a digital audio/video signal (SAV), means for demodulating and decoding the input signal into an output signal intended for the television receiver, and a first buffer memory (8) into which the input signal is diverted after demodulation (SD) when the decoder is placed in a so-called “live” mode of operation. In a so-called “playback” mode of operation, the signal recorded in the first buffer memory constitutes the output signal. This decoder comprises a second buffer memory (9) into which the demodulated input signal (SD) is diverted when the decoder is placed in the “playback” mode, the signal recorded in the second buffer memory (9) constituting the output signal when the decoder is switched from the “playback” mode to another so-called “return to live” mode of operation. In the “return to live” mode, the user views at high speed the video portion recorded in the second buffer memory before the decoder switches back to the “live” mode.

摘要： A multicore system 2 includes a main system program 610 that operates on a first processor core 61 and stores synthesized audio data, which is mixed audio data, to a buffer for DMA transfer 63, a standby program 620 that operates on a second processor 62, and an audio output unit 64 that sequentially stores the synthesized audio data transferred from the buffer for DMA transfer 63 and plays the stored synthesized audio data. When an amount of storage of the synthesized audio data stored to the buffer for DMA transfer 63 has not reached a predetermined amount of data determined according to the amount of storage of the synthesized audio data stored to the audio output unit 64, the standby system program 620 takes over and executes the mixing and the storage of the synthesized audio data that is executed by the main system program 610.
