Abstract: The power consumption of a search engine such as a CAM device is dynamically adjusted to prevent performance degradation and/or damage resulting from overheating. For some embodiments, the CAM device is continuously sampled to generate sampling signals indicating the number of active states and number of compare operations performed during each sampling period. The sampling signals are accumulated to generate an estimated device power profile, which is compared with reference values corresponding to predetermined power levels to generate a dynamic power control signal indicating predicted increases in the device's operating temperature resulting from its power consumption. The dynamic power control signal is then used to selectively reduce the input data rate of the CAM device, thereby reducing power consumption and allowing the device to cool.

Abstract: In a wireless transmission method, an input data signal corresponding to a serial combination of a first transmit data signal and a second transmit data signal is received. The first and second transmit data signals are phase-modulated with different first and second spreading code signals to produce first and second DSSS transmit signals, which are serially output as a baseband transmit signal that is up-converted to a selected wireless transmission frequency range. The first and second phase-modulated signals are serially output as a baseband transmit signal. In a wireless reception method, an input receive signal is down-converted to a baseband receive signal corresponding to a serial combination of first and second time-interleaved DSSS receive signals in a baseband frequency range. The first and second DSSS receive signals are phase-demodulated with different first and second de-spreading code signals to produce first and second receive data signals.

Abstract: The embodiments that are described herein provide random access to individual data storage locations of a group of buffers, which may be scattered in the memory. These embodiments provide a virtual memory interface that applies virtual addresses in a flat memory linear addressing space as indices into the physical memory addresses that are ordered into a sequence in accordance with the group of buffers. In this way, these embodiments enable a device (e.g., a processor) to directly and sequentially access all of the scattered physical memory locations of a fragmented data item, such as a packet, without having to perform any memory segmentation or paging processes. In some embodiments, these accesses include both read and write accesses to the scattered data storage locations.

Abstract: A technique for forwarding multi-cast data packets in a communication network. Multi-cast packets are broadcast to every output port of the switch. The packet is thus buffered in each port. Then, all of the output ports, save those that are appropriate output ports for the packet, drop the packet. Accordingly, the output ports that did not drop the packet forward the packet to the network. A control packet that follows the packet may then instruct the ports regarding which ports are to drop the packet and which ports are to forward the packet. This technique has an advantage of efficiently handling multi-cast packets.
