Embodiments of the present invention provide a compact representation of a cumulative bit curve formed from piece-wise straight line approximations between upper and lower bounds about an actual cumulative bit curve (CBC).

In terms of line-fitting algorithms that are used, several different algorithms may be used of differing complexities, with the intention of trying to minimize the number of end-points required of within the piecewise approximation. |

Method and apparatus for determining propagation delay in a network
A propagation delay in the transmission of a frame from an initiator node to a peer node is determined by initially identifying a frame number and byte offset of a first incoming frame from the peer node at a time when the initiator node outputs a portion of a transmitted frame. The portion of the transmitted frame may be the first byte of a sub-frame within the transmitted frame. At the peer node, the frame number and byte offset of a second frame to be supplied to the initiator node is identified at a later time when the frame portion transmitted by the initiator node is received by the peer node, and such information is transmitted to the initiator node. Thus, since the frames output and received by the initiator node are typically of fixed duration, the frame number and byte offset of the incoming frame represent the time when the initiator node outputs the frame portion (a transmit time). In addition, the frame number and byte offset of the second frame represents the time at which the frame portion is received by the peer node (a receive time). Accordingly, by comparing the frame numbers and byte offsets of the first and second frames received from the peer node, a difference between transmit and receive times or propagation delay can be obtained. |

During the read operation, a bit line is coupled to a supply voltage through a bit cell memory element that has different resistances at logic states “0” and “1.” A reference bit line is coupled to the supply voltage through a comparison resistance value, especially a resistance between high and low resistance of the memory element in the two logic states. Voltages on the bit line and reference bit line ramp toward a switching threshold at rates related to the resistance values. The first line to discharge to switching threshold voltage sets the sense circuit latch. |
