A method and system for a merchandise checkout system utilizes a remote scanning device, a shopping cart and bags for allowing a purchaser to buy merchandise unassisted by store personnel. The remote scanning device reads product identity information from coded levels on products chosen by the purchaser and sends the information to a central processor. The central processor has a memory, which indexes price information and weight for each product based on the product identity information. The central processor sends an accumulated price and weight transaction to the remote scanning device for the purchaser's use. The product identity information on the products further include a security tag device which is deactivated by the remote scanning device. The purchaser upon completion of their purchases takes their shopping cart to a security station for weighing in on a scale wherein an actual combined weight of the shopping cart, bags and products is compared to a predicted weight determined by the central processor and generating a notification signal if a discrepancy occurs. The security station further verifies that the security tag devices have been deactivated and also generates a notification signal. The purchaser next goes to a payment checkout terminal coupled to the central processor, wherein the payment checkout terminal effects financial transactions including acceptance of payment for transactions initiated by the remote scanning device, and the payment checkout terminal is operable by store personnel only.

The invention relates to a virtual network card interrupt control method for a plurality of virtual machines, which comprises the following steps: reading a descriptor of a data packet firstly to obtain information of a DMA source address, a destination address, length, and the like when a network card receives or transmits the data packet; then, executing DMA operation, back writing the descriptor after the operation is completed; counting by a counter corresponding to a virtual machine queue; transmitting an interrupt request when a numerical value of the counter reaches a preset time threshold value; carrying out the counting operation of the counter when the counter operates; when the numerical value of the counter reaches a preset time threshold value, judging whether the data packetcompletes the operation or not, if completing the operation, transmitting the interrupt request, otherwise, transmitting the interrupt request after the data packet completes the operation, and setting immediate interrupt operation without being restrained by the two threshold values as required. The network card interrupt control method completes the interrupt operation of the original software layer by hardware, completely releases the CPU and reduces the utilization ratio of the CPU, and meanwhile, because the processing speed of the hardware is greatly higher than the processing speed of the software, the data processing speed is greatly increased.

A transcoder system for compressed digital video bitstreams comprising three frame types: I-frames, P-frames and B-frames. The system includes a picture reader decoder to ascertain the type of each frame prior to transcoding. The system also includes a T₂ transcoder for processing I-frames and P-frames, possibly excepting the last P-frame of a group-of-frames (GOP), a T₁ transcoder for processing B-frames and (optionally) the last P-frame of a GOP and a picture decision block for separating all frames into I-frames and P-frames, possibly excepting the last P-frame of a GOP for processing by the T₂ transcoder and B-frames and (optionally) the last P-frame of a GOP for processing by said T₁ transcoder. Another component is a remerge block for recombining the output of all frames from said T₁ transcoder and the T₂ transcoder into a reconstituted output bitstream, such that most of the frames are processed by the much faster T₁ transcoder, thereby achieving substantial improvement in the transcoding throughput speed while retaining a low error rate.

The invention discloses a limited gibberish text one-way conversion method and an encryption/decryption application thereof. The limited gibberish text one-way conversion method includes subjecting an initial gibberish text to one-way conversion with limited times and exclusive OR with message.

Compared with the traditional standard encryption/decryption method, the limited gibberish text one-way conversion method has the advantages that with fewer bandwidth spent, the encryption/decryption speed is improved by 10-100 times at the premise that the data safety is guaranteed; method is simple and widely applicable to large-scale data storage and transmission.

A row addressing circuit for DRAM memory is disclosed. Additional address or mode bits are used to dynamically select between long page and short page access modes, and to dynamically select between single cell per bit and dual, or two cell per bit modes in each memory bank within a memory block. In the short page access mode, only one wordline in a memory block is activated. In the long page access mode, two wordlines in the memory block are activated for accessing twice the number of bits as in short page access mode. In the single cell per bit mode, one bit of data is stored in one DRAM cell. In the two cell per bit mode, the row addressing circuit simultaneously activates two wordlines in a bank of the memory block to access one DRAM cell connected to each bitline of a pair of complementary bitlines for writing and reading complementary data. The row addressing circuit can combine the different access modes for system design flexibility.
