摘要： A system, method and program product for retaining a logic state of a processor pipeline architecture are disclosed. A comparator is positioned between two stages of the processor pipeline architecture. A storage capacitor is coupled between a storage node of the comparator and a ground to store an output of the early one of the two stages. A reference logic is provided, which has the same value as the output of the early stage. A logic storing and dividing device is coupled between the reference logic and a reference node of the comparator to generate a logic at the reference node, which is a fraction of the reference logic, and to retain a logic state of the information stored on the storage capacitor. Further mechanisms are provided to determine validity of data stored in the logic storing and dividing device.

摘要： A field programmable gate array (FPGA) device including a non-non-programming-based default power-on electronic configuration. The non-non-programming-based default power-on electronic configuration defines a default state to initial a first logic function. Upon power-up, the FPGA device would be enabled to enter the default state without having first to be configured via a conventional programming mode, thus saving precious processing time during power-up. Several embodiments are disclosed, such as a mask via circuit, an asynchronized set/reset circuit, an unbalanced latch circuit and a flush and scan circuit. A related method is also disclosed to reduce the memory size dedicated to the first logic function to facilitate further programming after power-up. In addition to time saving and further programming, the FPGA device can also allow partial or incremental programming to expand the full functionality to match customer's different needs.

摘要： A reconfigurable logic array (RLA) system (104) that includes an RLA (108) and a programmer (112) for reprogramming the RLA on a cyclical basis. A function (F) requiring a larger amount of logic than contained in the RLA is partitioned into multiple functional blocks (FB 1, FB2, FB3). The programmer contains software (144) that partitions the RLA into a function region FR located between two storage regions SR1, SR2. The programmer then programs functional region sequentially with the functional blocks of the function so that the functional blocks process in alternating directions between the storage regions. While the programmer is reconfiguring function region with the next functional block and reconfiguring one of the storage regions for receiving the output of the next functional block, data being passed from the current functional block to the next functional block is held in the other storage region.

摘要： A method for increasing the manufacturing yield of field programmable gate arrays (FPGAS) or other programmable logic devices (PLDs). An FPGA or other PLD is formed in several sections, each of the sections having its own power bus and input/output connections. Each section of the FPGA or other PLD is tested to identify defects in the FPGA or other PLD. The FPGA or other PLD is sorted according to whether the section has an acceptable number of defects. An assigned unique number for the FPGA or other PLD chip or part identifies it as partially good. Software for execution and configuring the FPGA or other PLD may use the unique number for programming only the identified functional sections of the FPGA or other PLD. The result is an increase in yield as partially good FPGAs or other PLDs may still be utilized.

摘要： A method for protecting a dynamically reconfigurable computing system includes generating an encoding signature and passing the encoding signature, through a system level bus, to at least one field programmable logic device and to a function library included within the system. The function library contains a plurality of functions for selective programming into the at least one field programmable logic device. A lock is generated so as to prevent external resources with respect to the system from accessing the encoding signature during the passing thereof.

摘要： A field programmable gate array is described for use in a semiconductor chip such as a VLSI chip. The array is provided with variable wire-through porosity to allow for optimum chip-level routing through the array. This is achieved by dividing the array into blocks which can be individually assessed for required porosity. Then blocks that have been prefabricated with differing porosities are placed in the macro to optimize local chip level routing. The routing of wires is determined by developing a chip floor plan to include early timing allocation and a proposed placement of the array. The floor plan is then overlaid with critical logical wiring nets. From this, an initial selection of blocks is made based on proposed wiring density, and the macro is assembled with the blocks strategically placed therein. The procedure is likewise applicable to other types of densely obstructed cores embedded with a chip.
