Abstract: An optimized system and method for a parallel leading zero anticipation which ascertains “end of run” patterns in parallel. A string representing the operands of the floating-point addition is divided into nibbles of predetermined bit length (normally 4 bits). Each nibble is analyzed for the end of run patterns and the results from this analysis determine whether a run of leading zero's or one's has ended within the nibble, and if there has been an end of run, the location (bit) of the end of run. The highest order nibble that has an end of run provides the higher order bits in the LZA (leading zero anticipator output) value, while the lower two bits of the LZA value are correlated from the location end of run within the nibble, as previously determined.

Abstract: The middle of line segments may be drawn on a computer display using an iterative method that reduces the number of calculations required. The process is repeated for each column. The first pixel is plotted according to a formula that allows the first pixel to best represent the location of the line in the column. A second pixel is then plotted either above, below, to the left of, or the right of the first pixel depending on the direction of the line. A normalized intensity value between 0 and 1.0 is then assigned to the first pixel according to the amount of area above, below, to the left of, or the right of the line in the first pixel depending on the direction of the line. This value may be assigned using a variable computed in plotting the first pixel. A normalized intensity value for the second pixel equal to 1.0 minus the normalized intensity value of the first pixel may then be assigned. Finally, the first and second pixels are shaded according to the normalized intensity values.

Abstract: Techniques for developing and exchanging virtual machine implementations and/or support library implementations are described. In one embodiment, the virtual machine design specifies a set of functions for executing all or substantially all support library operations that are dependent on the implementation of the virtual machine. When a developer desires to substitute one virtual machine implementation for another, the developer is able to basically “plug-in” the second virtual machine implementation with minimal impact on the support libraries since both virtual machine implementations provide implementations for the set of specified functions that are dependent on the implementation of the respective virtual machine. Conversely, different support libraries may be utilized in conjunction with a particular virtual machine implementation.

Abstract: A system and method are provided for managing information concerning a network flow comprising packets sent from a source entity to a destination entity served by a network interface. A network flow is established for each datagram sent from the source entity to the destination entity. A flow key, identifying the source and destination entities, is stored in a data structure along with information concerning validity of the flow, sequence of data in the flow datagram and how recently the flow was active. Once a flow is established, it is updated each time a packet containing data from the flow's datagram is received. When such a packet is received, an operation code is generated for identifying whether the packet is suitable for a particular network interface function. An operation code may, for example, indicate that a packet contains data to be re-assembled with other data from the same flow. Another operation code may indicate that a packet is not suitable for data re-assembly.
