摘要： Broadly speaking, an apparatus for efficiently utilizing a shared packet buffer memory in a switch and a method for operating the same is provided. More specifically, the apparatus includes a memory having a number of buffers configured to be operated in a ratcheted manner. The ratcheted manner in which the memory is operated causes each incoming data stream to be distributed across the number of buffers. Each stored data stream can also be retrieved from the number of buffers for output from the memory in a similar ratcheted manner. The memory uses a rotating selector to control the ratcheted manner of operation. Also, the memory is capable of simultaneously servicing each of a number of inputs and a number of outputs to which the memory is connected.

摘要： Broadly speaking, a device for addressing a shared resource is disclosed. The device includes at least one register in communication with the shared resource. The at least one register is configured to hold an address that is to be provided to the shared resource upon receipt of a clock signal. The device also includes a multiplexer for providing a next address to the at least one register. The multiplexer is disposed outside of a critical timing path for addressing the shared resource. The device for addressing the shared resource allows multiple users to be connected to the shared resource without adversely affecting both a speed of the shared resource and a number of users that can be achieved in an actual implementation of the shared resource.

摘要： Broadly speaking, a bandwidth matching device is provided for transforming a number of incoming data streams each having a first bandwidth into an outgoing data stream having a second bandwidth. More specifically, the bandwidth matching device provides an assembler and a disassembler. The assembler incorporates a stepped arrangement of cells for transforming the number of incoming data streams having a given bandwidth into an outgoing data stream having a larger bandwidth, wherein each portion of the outgoing data stream represents a concatenation of a number of portions of each of the incoming data streams. As a complement to the assembler, the disassembler uses a stepped arrangement of cells to transform the concatenated output generated by the assembler back into the number of incoming data streams originally received by the assembler.
