  • Publication number: 20090089551
    Abstract: Provided are a method and apparatus for avoiding bank conflict. A first instruction that is one of access instructions that are predicted to cause the bank conflict is replaced with a second instruction by changing an execute timing of the first instruction to a timing prior to the execute timing of the first instruction so as for the access instructions not to cause the bank conflict. Next, a load/store unit that is scheduled to access the bank according to the first instruction accesses the bank and reads out a data from the bank at an execute timing of the second instruction, and after that, the load/store unit is allowed to be inputted the read data at the execute timing of the first instruction. Accordingly, although the access instructions that are predicted to cause the bank conflict are allocated to the load/store units, the bank conflict can be prevented, so that it is possible to avoid deterioration in performance due the occurrence of the bank conflict.

  • Publication number: 20090073163
    Abstract: An apparatus for and method of processing a vertex in relation to 3 dimensional (3D) graphics pipeline are provided. According to the method, while a processor processes vertex data in units of batches, vertex data corresponding to a batch to be processed next is extracted and temporarily stored in a buffer independently of the processor. If the processor finishes processing of the current batch, the batch stored in the buffer is output so that the processor can immediately process the batch.

  • Patent number: 7056461
    Abstract: A method of producing a polyethylene terephthalate-based polyester fiber includes spinning polyethylene terephthalate based polyester to produce an undrawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1338 g/cm3 or more, multi-stage drawing the undrawn yarn, heat-setting the drawn yarn, relaxing heat-set yarn, and winding the relaxed yarn to produce the resulting drawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1.38 to 1.3865 g/cm3, so that the thusly produced industrial polyester yarn with high modulus and low shrinkage contributes to significantly improving strength retention (tenacity of a dip cord/tenacity of a grey yarn) of the dip cord, produced by treating the polyester yarn with an adhesive (RFL) and subsequently heat-treating the RFL-treated polyester yarn, to be useful as a tire cord.

  • Patent number: 5824438
    Abstract: The structure of a phase shift mask and a method of manufacturing the same are disclosed. A phase shifting mask in accordance with the present invention comprises a light transmitting substrate, a phase shifting layer formed on the upper side of the light transmitting substrate, an adhesive layer formed on the phase shifting layer, and a light shielding layer formed on the adhesive layer. Accordingly, when etching the phase shifting layer, the light shielding layer is protected by the adhesive layer. The adhesive strength is increased due to the adhesive layer formed between the phase shifting layer and the light shielding layer, thereby much improving the reliability of the phase shifting mask.

    Abstract: An exercise unit for applying a rectilinear vibration and a swing vibration to the user. The exercise unit is divided into a lateral vibration part and a swing vibration part which are driven by two separated driving motor respectively. The lateral vibration part converts a rotative motion of the motor into a rectilinear vibrating motion to provide the user with the rectilinear vibration. The swing vibration part converts the rotative motion into a swing vibrating motion to provide the user with the swing vibration. The two parts may be selectively driven by a single driving motor.
