摘要： An apparatus and method for dynamically allocating memory between inbound and outbound paths of a networking protocol handler so as to optimize the ratio of a given amount of memory between the inbound and outbound buffers is presented. Dedicated but sharable buffer memory is provided for both the inbound and outbound processors of a computer network. Buffer memory is managed so as to dynamically alter what portion of memory is used to receive and store incoming data packets or to transmit outgoing data packets. Use of the present invention reduces throttling of data rate transmissions and other memory access bottlenecks associated with conventional fixed-memory network systems.

摘要： A data communication controller processes incoming data frames. The controller includes a pre-processing block for receiving data frames and a frame processing unit coupled to the pre-processing block. The pre-processing block is configured to compare header fields of a current frame with header fields of a previous frame. The pre-processing block provides an output signal to the frame processing unit on the basis of the comparison of the header fields of the current and previous frames. The controller may operate in accordance with the Fiber Channel protocol, and the output signal may include bits to indicate that the current frame is of the same exchange, of the same sequence, and is next in sequence relative to the previous frame.

摘要： An adder which takes advantage of the early arriving bits of a time skewed operand to provide a result to an add or substract operation without additional latency. Possible partial results are calculated and then selectively combined according to the late arriving data as the late arriving data becomes available. In an embodiment of the present invention, a first operand is partitioned into groups according to the arrival time of the skewed data, and possible partial results for each group are calculated for the full range of partial inputs that affect it. In addition, the high order groups are calculated with and without a borrow (carry) which is propagated from a low order group. Once the delayed partial operands are known and the borrows (carrys) determined the partial results are gated through multiplexers according to the borrows and partial results, and thus the result is provided with a delay similar to the delay in arrival of the skewed operand.

摘要： A system implementing a methodology for determining the exponent in parallel with determining the fractional shift during normalization according to partitioning the exponent into partial exponent groups according to the fractional shift data flow, determining all possible partial exponent values for each partial exponent group according to the fractional data flow, and providing the exponent by selectively combining possible partial exponents from each partial exponent group according to the fractional data flow. There is also provided a system implementing a methodology for generating the sticky bit during normalization. Sticky bit information is precalculated and multiplexed according to the fractional dataflow. In an embodiment of the invention, group sticky signals are calculated in tree form, each group sticky having a number of possible sticky bits corresponding to the shift increment amount of the multiplexing. The group sticky bits are further multiplexed according to subsequent shift amounts in the fractional dataflow to provide an output sticky bit at substantially the same time as when the final fractional shift amount is available, and thereby at substantially the same time as the normalized fraction.
