摘要： An apparatus for selecting a reference line for image data compression including a plurality of mutually connected reference selector chips for selecting a reference scan line from vertical mode coding of image data. The reference selector chips select a reference scan line from a plurality of preceding scan lines in exclusive or combination of the image data of each candidate reference scan line with the image data from the input scan line. The candidate reference scan line that has the lowest number of dissimilar bits is selected as the reference scan line. Each candidate reference scan line has associated therewith a register having bit positions arranged from the highest order bit position to a lowest order bit position for storing a binary sum of the number of dissimilar bits. When the sums are compared, the binary value and successive bit positions are compared from the highest order bit position to the lowest order bit position. When the binary value for a compared bit position of a register is greater than the binary value in the corresponding bit position of another register, each reference selector chip generates a losing signal for indicating that the register lost the arbitration. When the lowest order bit position of a register is not greater than the lowest order bit position of any other register and no losing signal was generated for the register, the associated chip generates a winning signal for indicating which candidate reference scan line had the least number of bits dissimilar to the corresponding bits in the input scan line. Each chip further includes a circuit for establishing a priority among the candidate reference scan lines so that two registers both having the smallest binary sum will not create a deadlock.

摘要： A system, method and computer program product are provided. In use, a plurality of flows associated with packets destined for an output port is identified. A utilization associated with the output port is further measured. Thus, rates of a plurality of the flows destined for the output port may be individually controlled at an input port thereof, based on the utilization to ensure that the utilization remains less than 99.9% and avoid buffering more than 400 packets with a correspondingly low delay.

摘要： Methods and apparatus for the Transporting of Fibre Channel data over Ethernet are disclosed. In one embodiment of the invention, Fibre Channel data frame and primitive signals are transported over Ethernet instead of using the Fibre Channel FC-1 and FC-0 protocols. This allows less expensive Ethernet equipment and devices to transport and perform services for Fibre Channel connected devices without having a physical Fibre Channel interface. The ability to provide Fibre Channel services and functions without having a physical Fibre Channel interface allows Ethernet equipment to be placed into service as SAN components.

摘要： A logic circuit comprises a dual rail drive circuit having a first rail and a second rail. The logic circuit further comprises a logic block having a first input coupled to receive an input signal from the first rail of the dual rail driver, and a second input coupled to receive an input signal from the second rail of the dual rail driver. In one embodiment, the input signal from the first rail of the dual rail driver can swing to a voltage level sufficient to turn on a p-channel transistor, and the input signal from the second rail of the dual rail driver can swing to a voltage level sufficient to turn on an n-channel transistor. For example, for a 0.18 micron process the input signal from the first rail may have a voltage swing from VDD to VDD-400 MV, and the input signal from the second rail may a voltage swing from GROUND to 400 MV.

摘要： A method and apparatus for improving the performance of data compression processes, such as relative address coding, CCITT standard facsimile processes, and similar two-dimensional image coding processes, by block coding one or more of the vertical mode codes produced by these processes. The performance of data compression processes is improved by representing one or more sequences of vertical mode code words with a single block code word. A reference scan line is preferably selected from among a plurality of previous scan lines, for example, the immediately preceding ten scan lines, for two-dimensional image coding. The previous scan line which is most similar to the current scan line to be coded is selected as the reference scan line. The selected reference scan line is then fed with the current scan line to be coded to a two-dimensional data compression coding process so as to yield a first tier of data compression. The image data are preferably checked during the two-dimensional data compression coding process for a predetermined run of a given vertical mode code, and a preselected block code is substituted if the predetermined run of the given vertical mode code appears so as to yield a second tier of data compression. Preferably, eleven consecutive vertical offset zero code words are represented by a single block code word. This provides enhanced data compression and reduces the amount of image data stored or transmitted and concomitantly lowers the cost for operation of the image data storage or transmission apparatus.
