摘要： A switch includes a reserved pool of buffers in a shared memory. The reserved pool of buffers is reserved for exclusive use by an egress port. The switch includes pool select logic which selects a free buffer from the reserved pool for storing data received from an ingress port to be forwarded to the egress port. The shared memory also includes a shared pool of buffers. The shared pool of buffers is shared by a plurality of egress ports. The pool select logic selects a free buffer in the shared pool upon detecting no free buffer in the reserved pool. The shared memory may also include a multicast pool of buffers. The multicast pool of buffers is shared by a plurality of egress ports. The pool select logic selects a free buffer in the multicast pool upon detecting an IP Multicast data packet received from an ingress port.

摘要： A checksum engine for use with a fast pattern processor and a method of operation thereof. In one embodiment, the checksum engine includes a processing engine that performs partial checksums on at least a portion of each processing block associated with different protocol data units (PDUs), and a controller that coordinates an operation of the processing engine to allow the processing engine to provide a complete checksum from the partial checksums of the processing blocks associated with each of the PDUs.

摘要： A switch applies back pressure to an ingress port while an output queue is congested. The switch includes an output queue associated with an egress port in the switch. The output queue stores packet pointers to data to be transmitted to the egress port. A back pressure controller in the switch applies back pressure to an ingress port while the output queue is congested upon receiving data at the ingress port to be transmitted to the egress port.

摘要： A multiple beam linear accelerator system and method where two or more accelerator waveguides are driven by a single high power microwave source. A single RF power system is multiplexed to drive the plurality of accelerator waveguides. Each accelerator waveguide is addressed at a different RF frequency, and the microwave source generates pulses at the appropriate RF frequency for each accelerator waveguide on a pulse-by-pulse basis.

摘要： An improved apparatus and method is disclosed for controlling the position of one moveable member relative to another. In the disclosed preferred embodiment of a rotating disk memory system, the moving member is a head carriage structure and the other is a frame carrying a rotating data storage disk. From externally supplied position selectron information, and from internally determined polyphase position information, open loop position changing movements are determined and carried out in accordance with monitored incremental polyphase position information generated during the movement. When a destination location has been reached one or more servo systems close loop in order to maintain the moving member precisely at the newly commanded location. A rotor for moving the member is an aspect of the present invention.

摘要： An LED driver IC for driving external strings of LEDs comprises a prefix register and a data register connected in series with each other and with the prefix and data registers in other driver ICs. The prefix and data registers of the driver ICs are connected in a daisy chain arrangement with an interface IC. The interface IC loads data identifying a functional latch into the prefix register and data defining a functional condition into the data register of each driver IC. The data in the data register is then transferred to the functional latch to control the functional condition within the LED driver IC.
