Abstract: Systems and methods for an SDN switch that provides application-based conditional forwarding and session-aware load balancing are provided. According to one embodiment, a packet is received at an input port of a Software Defined Networking (SDN) switch. The packet is forwarded by the SDN switch to a first flow processing unit (FPU) of multiple FPUs of the SDN switch. The first FPU determines whether the packet is to be tracked. And, if so, the received packet is transmitted to a second FPU of the SDN switch; otherwise, the packet is transmitted to a third FPU of the SDN switch. When the packet is received at the second FPU, the packet is conditionally forwarded by the SDN switch to an application device. When the packet is received at the third FPU, the packet is conditionally forwarded to an output port or dropped.

Abstract: Systems and methods for an SDN switch that provides service group chaining for sequentially serving multiple network security devices are provided. According to one embodiment, a packet received by the switch is processed by a first FPU based on a first set of rules and forwarded conditionally to a first security device. The packet is security processed, including dropping it or forwarding it to an egress port or forwarding it to a second FPU. When forwarded to the second FPU, the packet is processed based on a second set of rules by forwarding it to a second security device or dropping it or forwarding it to the egress port. When forwarded to the second security device, the packet is security processed, including dropping it or forwarding it to the egress port or conditionally forwarding it to a third FPU to be sequentially forwarded to a third security device.

Abstract: Systems and methods for an SDN switch that facilitates forwarding/differential routing decision determination are provided. A packet is received at an input port of the SDN switch. The switch includes a first and second set of flow processing units (FPUs). The packet is forwarded to a first FPU of the first set. Based on a flow table associated with the first FPU, it is determined whether the packet is to be forwarded to a network device or an output port. The packet is received from the network device at a second FPU of the second set. Based on a flow table associated with the second FPU, it is determined whether to execute one or more instructions to forward the packet to the input or output port, or to drop or default forward the packet to the input or output port.

Abstract: The display of a portion of an image in successive rows of display tiles in a tiled display system are delayed, so that the top portion of a first display tile is illuminated immediately after the bottom portion of a second display tile is illuminated, where the second display tile is adjacent to and above the first display tile. This removes the appearance of a broken up image when the image moves across the display tiles in a direction somewhat parallel to the direction of raster scanning. In this way, a raster scanning tiled display system does not produce a stair-step effect even though the top and bottom portion of an image on a tile in the tiled display system is raster-scanned at different times.

Abstract: Techniques and devices use panels or screens with pixels for display or illumination applications to achieve dithered pixel brightness beyond pixel brightness levels set by a digital to analog conversion (DAC) circuit module with a preset DAC resolution between two adjacent DAC levels. In one implementation, when a pixel is to be dictated by a digital pixel signal to operate within an unstable brightness region, a control mechanism is provided to control the DAC circuit module to operate the pixel in the block at a DAC level below the unstable brightness region or at a different DAC level above the respective unstable brightness region, to achieve a perceived brightness level within the respective unstable brightness region.

The present invention provides a control logic circuit for selecting between the parallel and serial modes. The present invention also includes a parallel and serial detection circuit. The control logic sends a signal to an interface circuit that selects between a serial programming mode and a parallel programming mode based on the outputs of the parallel and serial detection circuits.

Abstract: The present invention provides a clocking circuit allowing individual macrocells in a particular macrocell block of a CPLD to use different polarities of the same clock. The input clock pin can now drive all the macrocells directly, which can eliminate additional buffering states and improve the clock to out timing, Tco, by (for example) 300 ps. The clocks are presented directly to the clock selection multiplexers for each macrocell. Additional functioning may be realized by implementing additional configuration bits inside the clocking architecture.

Abstract: The present invention provides a circuit for supplying a verifying reference and measurement voltage for use in verifying the programming of a programmable cell. The present invention provides the verifying reference and measurement voltage through internal circuitry on the cell and eliminate any requirement for an externally provided reference voltage. The verifying voltage is provided by modifying the programming voltage. The programming voltage is stepped down or stepped up through the use of internal circuitry to provide the reference and measurement voltage.

Abstract: A high-speed programmable macrocell includes structure sufficient to implement a combined in the combinatorial storage signal path when the macrocell is operated in the combinatorial, and storage modes of operation. The macrocell includes, a master circuit (including a polarity multiplexer), and a slave circuit (including a transmission gate). The polarity multiplexer is responsive to input data for generating an output signal corresponding to one of a true and complemented state of the input data, according to a polarity configuration bit. The master circuit stores the multiplexer output in response to a low-to-high transition of a clock signal when operating in the storage mode. The master circuit, when in the combinatorial mode, will always pass the multiplexer output therethrough.
