Abstract: A high performance field programmable gate array is described with one or more signal processing engines coupled to a programmable logic fabric. Each signal processing engine includes a signal processing unit for performing specifying tasks and a bus-based configurable connection box for routing a bus-based input to a bus-based output. The signal processing unit has a floating point unit (FPU)/multiply accumulate (MAC) for computation and register files for storing information. The programmable logic fabric is coupled to the one or more signal processing engines for routing of information between the signal processing engines.

Abstract: A method and system are disclosed in which a Mobile Terminated SMS (Short Message Service) wireless message generated by a Computer Application containing an embedded response menu can be sent to a Mobile Handset and in which a Mobile Originated response from the Mobile Handset can be uniquely re-associated with the original Mobile Terminated message is described. Given that SMS provides no inherent association between Mobile Terminated and Mobile Originated messages, the method and system provide a scheme in which the original Computer Application menu response options are remapped to unique values prior to delivery to the Mobile Handset. When the response is received from the Mobile Handset, the method can uniquely re-associate and reverse map the response code back to the original Mobile Terminated message and original menu response options.

Abstract: A dedicated logic cell in a programmable logic structure is described that comprises the following primary components: a configurable logic function or look-up table (LL), a dedicated logic function (DL), a sequential logic function (LS), and a control logic function (LC). In this illustration, the dedicated logic cell comprises two configurable logic functions, two sequential logic functions, a dedicate logic function, and a control logic function. In a first embodiment, the dedicated logic cell is constructed with a combination of configurable logic functions that are coupled to a dedicated logic function in order to perform a four 2-input function, an AND function, an OR function, or an XOR function. In a second embodiment, the dedicated logic cell is constructed with a combination of configurable logic functions that are coupled to a dedicated logic function in order to perform a four 2-to-1 multiplexer function.

Abstract: A programmable system is disclosed having multiple configurable floating point units (“FPU”) that are coupled to multiple programmable logic and routing blocks and multiple memories. Each floating point unit has static configuration blocks and dynamic configuration blocks, where the dynamic configuration blocks can be reconfigured to perform a different floating point unit function. A floating point unit includes a pre-normalization for shifting an exponent calculation as well as shifting and aligning a mantissa, and a post-normalization for normalizing and rounding a received input. The post-normalization receives an input Z and realigns the input, normalizes the input and rounds the input Z.

Abstract: A method for clustering logic units in a field programmable integrated chip to generate a set of clusters is disclosed. The clustering step for forming a super cluster comprises a first logic element and a second logic unit a first logic unit and a super cluster, or a first super cluster and a second super cluster. The method includes generating all possible configurations by enumerating all possible two-way relationships combining a driver-and-receiver relationship from a pool of a finite number of dedicated connections. The set of all possible configurations is reduced to a subset of configurations based on one or more multi-dimension criteria. Each dimension in the multi-dimensional criteria is represented by a parameter. The method involves prioritizing a collection of parameters so that a set of selected parameters or a set of selected criteria is used to generate a desirable number of subsets of configurations.

Abstract: A programmable logic structure is disclosed employing input logic routing cell (ILRC) multiplexers and output logic routing cell (OLRC) multiplexers for making local connections between dedicated logic cells. In a simple programmable logic structure, a dedicated logic cell (DLC) is implemented in a programmable logic structure comprising multiple ILRC multiplexers for port A and multiple OLRC multiplexers for port B. In a multi-level programmable logic structure, multiple columns of dedicated logic cells is designed with columns of dedicated local cells adjacent to each other where each DLC column is used to implement a particular logic function. In a first embodiment, local connections can be made between dedicated logic cells, e.g. an OLRC in a first DLC at level L making local point-to-point connections to an ILRC in a second DLC at level L+1.

Abstract: An apparatus for controlling transmission of data packets in an information network comprises a Regional Transaction Processor (RTP) operable to communicate with a Data Enabling Device (DED) and at least one workstation. The DED searches data packets for content match information. The RTP includes instructions to generate information to include in a prompt to be presented at the workstation when the content match information is detected in at least one of the data packets. The prompt is based on information in the data packet. Transmission of the data packets through the information network is suspended by the DED until a response to the prompt is received that authorizes downloading the data packets to the workstation. If transmission of the data packets to the workstation is not authorized, the data packets are discarded by the DED.

Abstract: A method for obtaining data while facilitating keeping a minimum amount of state is provided. The method includes receiving at a first device an Internet Protocol (IP) frame sent from a second device to a third device wherein the first device is in a flow path between the second and third devices, the first device including at least one of an Application Specific Integrated Circuit (ASIC) and a Field Programmable Gate Array FPGA. The method also includes removing an embedded stream-oriented protocol frame including a header and a data packet from the received IP frame with at least one of the ASIC and the FPGA, and determining a validity of a checksum of the removed steam-oriented protocol header.
