摘要： This invention implements a variable-length code pipeline decoding process as hardware by providing additional bit processing means, reducing the load on external control, and clarifying encoded data shift means. For this purpose, in order to determine a code length and additional bit length, two different decode processes are executed, the overall process is separated into three stages, i.e., a stage for shifting out a code word of encoded data, a decode processing stage, and a symbol determination & additional bit processing stage, and these stages are executed in a pipeline manner.

摘要： Whether a header information processor quickly enters a program inactive state at the timing when it issues an operation start command of an encoding process for a predetermined processing unit to a variable-length code encoder, or the header information processor enters the program inactive state upon completion of execution steps to be processed is adaptively selected in accordance with the number of execution steps. One memory is shared by the header information processor and variable-length code encoder, and address input permission means for controlling to grant permission of an address input to the memory to one of the header information processor and the variable-length code encoder is provided. The memory is used as a work area of the header information processor, and as a storage area of a variable-length code table which is looked up by the variable-length code encoder.

摘要： An area where a specific object is captured is extracted as a specific area from the image of a frame of interest, and the evaluation value of the specific area is obtained using a predetermined evaluation formula. It is determined whether the evaluation value of the specific area in a frame preceding the frame of interest has exceeded a predetermined threshold. When it is determined that the evaluation value of the specific area has exceeded the predetermined threshold, the frame of interest is encoded to set the code amount of the specific area in the image of the frame of interest to be smaller than that of the specific area in the image of the frame preceding the frame of interest.

摘要： Address information generated and output by an address converter for each pixel of input image data in accordance with the phase based on the position of the pixel to be coded is stored in an address storage divided into address groups which are periodically referred to. Information indicative of the occurrence probability of the pixel to be coded and phase information of the pixel are selectively output from the address storage, and an arithmetic coding is performed for the output. During the processing, update data is written in to one group while a read-out is being performed for the other group. A template is constituted by excluding a pixel which predeses one pixel, and a prediction state in each phase is divided into two parts. The template output is applied to both of the divided storage devices, and read actions are independently performed.

摘要： In this invention, scan conversion processing of changing the scan order for each block is used. Parallel scan conversion processing is executed if possible, thereby making the number of scan conversion target blocks per unit time larger than before. To do this, a scan status holding unit holds statistical information based on the appearance frequency values of coefficients in a block. A scan order holding unit holds coefficient position information in which the coefficient positions in a block are arranged based on the scan order. A parallel number determination unit determines the number of blocks processable in parallel based on the statistical information held in the scan status holding unit and supplies the result to a scan conversion unit as a control signal. If the control signal from the parallel number determination unit indicates parallel processing, the scan conversion unit executes scan conversion of two input blocks in parallel.

摘要： A smart card comprises an IC module and an antenna for non-contact transmission. The IC module has both a contact-type function and a non-contact-type function. In the contact-type function, power reception and signal transmission/reception is effected via an electrical contact. In the non-contact-type function, power reception and signal transmission/reception is effected in a non-contact state by an electromagnetic coupling system without providing the IC card with an electrical contact. The IC module and the antenna comprise first and second coupler coils, respectively, which are disposed to be closely coupled to each other, and the IC module and the antenna are coupled in a non-contact state by transformer coupling. An antenna coil is disposed so as not to overlap an engagement portion for the IC module, which is a region of an external terminal electrode serving as a contact-type electrode, an embossing region, or a magnetic stripe region.

摘要： A vehicle including a vehicle frame and a power unit suspended from the vehicle frame in a manner to reduce the amplitude of vibration generated by the power unit and also the vibration transmitted to the vehicle frame. The power unit comprises a case, an engine integrally coupled to the case, a drive wheel rotatably supported on the case, and a transmission mechanism disposed in the case for transmitted power from the engine to the drive wheel. The power unit is supported on the vehicle frame by a linkage mechanism and a cushioning unit, the engine having a center where vibratory forces are produced and an associated direction in which primary vibratory forces are produced. The linkage mechanism includes a link extending in a direction substantially normal to the engine-associated direction. The power unit is constructed such that a first straight line extending horizontally and transversely of the vehicle frame through the center of gravity of the power unit and a second straight line extending through the engine's center in the engine-associated direction substantially intersect each other.
