    摘要： A radio communication system in which each frame having an imbalanced transmission speed is time-divided to a low speed transmission area and to a high speed transmission area according to a specified ratio in the time domain. An upload signal as a first-directional signal and a download signal as a second-directional signal are allocated to the low speed transmission area and to the high speed transmission area respectively. In a case where a high speed transmission request is issued from a personal station (PS) to a base station (BS), the order of the upload signal and that of the download signal is exchanged in the time domain within one frame, so that the download signal and the upload signal are allocated to the low speed transmission area and the high speed transmission area respectively.

    摘要： A cache memory device having circuitry for controlling operation of a sense amplifier for accessing an array in the data processing system including a cache memory device includes circuitry for enabling the sense amplifier when there is a hit in the array as a result of a read request and disables the sense amplifier when there is a miss in the array as a result of the read request. The cache memory device may receives an address associated with the read request, and compares the address to addresses associated with entries in the array, wherein a hit results when the received address matches at least one of the addresses associated with the entries in the array, and wherein a miss results when the received address does not match at least one of the addresses associated with the entries in the array. The address associated with the read request and the addresses associated with entries in the array are effective addresses. The cache memory device may enable the sense amp only when the array is being accessed by the read request, and only after an entire address associated with the read request has been received.

    摘要： A data recording disk file includes rotatable disks with concentric data tracks thereon. The data disk file includes servo information recorded on at least one of the disks, at least one head for reading the servo information during rotation of the disk, and a voice coil motor (VCM) attached to the head for positioning the head relative to the data tracks. A servo is driven by signals read from the head to control the VCM. The servo includes a processor employing an estimator model for estimating the parameters of the VCM and for generating, from the estimated parameters and the servo information, a digital control signal. The digital control signal is converted to an analog control signal. The control signal is applied to a power amplifier which generates an input current for use by the VCM. The processor provides solely a single estimator model which operates in both saturated mode and linear mode depending on the magnitude of the digital PES. In the processor, a discrete model is formed by using a linear continuous model in which the effect of the back electromotive force (emf) is implicitly added into the model, and the current rise time in the VCM is ignored. The processor employs an adaptive estimator model which adjusts its calculations based on both calibrated overall servo gain and the VCM torque constant. The processor also employs a technique used during calibration to identify the average VCM torque constant. The processor employs a technique used during calibration to identify head offsets. The servo includes a short seek and head switch technique which adaptively adjusts the estimator position, the feed forward durations and magnitude based on the identified head offsets.
