摘要:
A liquid crystal display panel driving device is provided which is capable of reliably improving a response speed of a liquid crystal and of obtaining good display quality. When overshooting driving is performed in a current frame for displaying, an excessive response level in a next frame is predicted based on a combination of a gray level in one past frame and a gray level in a current frame and, when an excessive response is predicted, a corrected gray-level value to prevent (or to cancel) the excessive response is calculated in advance. By applying a voltage corresponding to the corrected gray-level value, an excessive response in a next frame can be suppressed. Irrespective of whether or not an excessive response is predictable in a next frame, an overshooting driving can be performed at an applied voltage sufficiently corresponding to a target gray-level value and, as a result, a response speed of a liquid crystal can be reliably made high and good display quality can be obtained.

A control device includes an arrangement for deriving an input torque input to a belt-type continuously variable transmission based on a control amount of a first actuator. The continuously variable transmission includes a first actuator that is provided on a one movable sheave side, that presses the one movable sheave toward one fixed sheave, and that can generate a belt pinching pressure on the one movable sheave side, and a second actuator and a torque cam that are provided on the other movable sheave side, that press the other movable sheave toward the other fixed sheave, and that can generate a belt pinching pressure on the other movable sheave side.

A cache memory device that connects an instruction controlling unit outputting a memory access request for requesting data and a storage device storing data, the cache memory device including: a data memory unit that holds data for each cache line, a tag memory unit that holds, for each cache line linked with a cache line of the data memory unit, tag addresses specifying storage positions of data covered by the memory access request at the storage device and status data indicating states of the data of the data memory unit corresponding to the tag addresses, a search unit that searches for a cache line of the tag memory unit corresponding to an index address included in the memory access request, a comparison unit that compares a tag address held in the found cache line of the tag memory unit and a tag address included in the memory access request and, when the two do not match, detects a “cache miss” and reads out the status information of the found cache line, and a controlling unit that, when the comparison unit detects a cache miss, requests data covered by the memory access request to the storage device and, when the cache line storing the data requested at the storage device is not present in the data memory unit, stops the supply of a clock to the data memory unit based on the status information of the cache line that the comparison unit read out.

In an information processing apparatus of this invention having a cache memory, a TLB and a TSB, a second retrieval unit retrieves a second physical address from an address translation buffer by using a second virtual address corresponding one-to-one to a first virtual address, and a prefetch controller enters a first address translation pair of the first virtual address from an address translation table into a cache memory by using a second physical address which is a result of the retrieval, thereby largely shortening the processing time of a memory access when a TLB miss occurs at the time of the memory access.

An arithmetic processing apparatus includes: a plurality of TLBs holding as entries a portion of a conversion table for conversion of virtual addresses into physical addresses that has been placed in a main memory unit; an entry registration determining unit that, while registering an entry output from the main memory unit in any one of a plurality of TLBs, determines whether an entry has already been registered in an area of a TLB as registration destination; and a relocation control unit that, when the entry registration determining unit determines that an entry has already been registered in the area of the TLB as registration destination, evicts the entry that has already been registered and registers evicted entry in other TLB.
摘要:
A transmitting side (101) transmits broadcast content (100) through a communication network (111) or a broadcast network (110). Transmission through the communication network (111) involves an addition of an IP header (100b) to the broadcast content (100) for packetization as an IP packet (100a) and transmission to a terminal device (112) on a receiving side (102). Transmission through the broadcast network (110) involves encapsulation of the IP packet into a given transmission packet (105) used with a digital broadcast signal for transmission to the terminal device on the receiving side (102).

A relay apparatus (110) includes a communication I/F (113) that receives an IP packet from a source terminal (120A) via a communication network (101), a broadcast wave interface (114) that transmits the IP packet received via the communication network I/F (113) to a destination terminal (120B) by a digital broadcast wave, and a receiving and transmitting unit (111) that transmits the IP packet that is received by the communication I/F (113) and transmitted by the transmitting communication terminal (120A) to the destination terminal (120B) via the broadcast wave I/F (114).
摘要:
A continuous crystallization process comprising the steps of supplying a crystallization material containing bisphenol A to a crystallizer to form crystals of an adduct of bisphenol A and phenol or crystals of bisphenol A, subjecting the slurry discharged from the crystallizer to solid/liquid separation, and recovering the crystals, wherein part of the mother liquor is circulated to the crystallizer. According to this process, the heat duty to be removed is reduced, deposition of solids on the inner surfaces of the crystallizer, particularly on the heat transferring surface of the cooler is restrained, and consequently the continuous operating time of the apparatus is prolonged.

An apparatus has program analysis information generation device for automatically generating program analysis information by analyzing a computer program, and program analysis information storage device for sequentially storing the generated program analysis information in a predetermined data recording medium in arbitrary units. A plurality of kinds of program analysis information generated by the program analysis information generation device are stored in the data recording medium as a database every time individual analysis information is obtained. Hence, upon obtaining program analysis information for a large-scale program, even when the memory capacity that can be mounted on a computer is limited, target program analysis information can be reliably obtained without encountering any memory shortage during analysis.
摘要:
In a defect counting method and apparatus, a projection or a corner of a defect area is successively identified from a pixel and pixels close to the pixel, especially, from four pixel groups. The number of the defect areas is incremented when the projection is identified and decremented when the corner is identified.
