A dynamic bus architecture is provided. This may include an encoding circuit coupled to a bus line and a decoder circuit coupled to the bus line. The encoder circuit may receive an input signal and generate an encoded signal on the bus line. The decoder circuit may receive the encoded signal from the bus line and generate the original unencoded signal. The encoder circuit may include a first flip-flop circuit to store a previous input signal from the bus line based on a clocking signal from the bus line. Additionally, the decoder circuit may include a second flip-flop circuit having a clock input to receive the encoded signal from the bus line as a clocking input.

Techniques and mechanisms for performing circuit-switched routing and packet-switched routing for network communication. In an embodiment, a router evaluates control information of a packet received by the router, the evaluation to detect whether the packet includes data for a sideband communication. Based on the evaluation, the router performs a selection from among a plurality of modes of the router, the plurality of modes including a first mode to route the packet for packet-switched communication of sideband data in a network. The plurality of modes also includes a second mode to configure a circuit-switched channel according to the packet. In another embodiment, the router determines a direction for routing a packet in a hierarchical network, wherein the determining of the direction is based on a level of the router in a hierarchy of the hierarchical network.

In accordance with some embodiments, the complexity of motion estimation algorithms that use Haar, SAD and Hadamard transforms may be reduced. In some embodiments, the number of summations may be reduced compared to existing techniques and some of the existing summations may be replaced with compare operations. In some embodiments, additions are replaced with compares in order to balance delay and area or energy or power considerations.

A method and apparatus for an address generation circuit. In one embodiment, the method includes computing a carry-in for at least one group of a predetermined number of bits of a propagate and a generate signal formed from a plurality of logical address components. Once the carry-in is computed, a plurality of conditional sums are generated for a logic 0 carry-in and a logic 1 carry-in. Subsequently, a sum is selected from the plurality of conditional sums to form a first portion of an effective address from the logical address components in a first stage and a second portion of the effective address in a second stage. In one embodiment, a fully dynamic high-performance sparse tree adder circuit that generates one in four carries, is used to form an address generation circuit, in accordance with one embodiment. Other embodiments are described and claimed.
