    摘要: A programmable optimized-distribution logic allocator enhances the speed, silicon utilization, logic efficiency, logic utilization, and scalability of very high-density CPLDs including the logic allocator. The programmable optimized-distribution logic allocator provides an optimized number of product terms to each I/O pin of the CPLDS and the same uniform number of product terms as feedback. However, no product terms are permanently connected to either a particular macrocell or a particular I/O pin. The programmable optimized-distribution logic allocator includes a multiplicity of router elements where each router element steers a sum of a selected number of sum-of-product terms from a PAL structure, i.e, a selected number of logic product-term clusters, to a programmably selected logic macrocell. Specifically, the programmable optimized-distribution logic allocator has a plurality of input lines, a plurality of output lines and a plurality of programmable router elements. Each programmable router element has an input terminal connected an input line in the plurality of input lines and an output terminal connected to an output line in the plurality of output lines.

The second hierarchical level resources include a programmable segment switch matrix connected to a plurality of input lines of the programmable block switch matrix. The CPLD in addition includes a third hierarchical level circuit having third hierarchial level resources connected to the second hierarchical level resources where a third hierarchical level signal path utilizes the third, second, and first hierarchical level resources. The third hierarchical level resources include a programmable global switch matrix having global switch matrix lines programmably connected to and disconnected from lines of the programmable segment switch matrix.

    摘要: Each programmable logic device in at least two families of high density segmented programmable array logic device utilizes a programmable switch interconnection matrix to couple an array of symmetric programmable logic blocks. Each programmable logic block includes programmable logic macrocells, programmable input/output macrocells, a logic allocator and a programmable product term array. The programmable switch matrix provides centralized global routing with a fixed path independent delay and decouples the logic macrocells from the product term array. The logic allocator decouples the product term array from the logic macrocells, and the I/O macrocells decouple the logic macrocells from the package I/O pins. The logic allocator steers product terms from the product term array to selected logic macrocells so that no product terms are permanently allocated to a specific logic macrocell. In a first PLD of each family, a first predetermined number of input lines couple the switch matrix to each programmable logic block. In a second PLD of each family, a second predetermined number of input lines couple the switch matrix to each programmable logic block. The number of input lines to each programmable logic block and to the switch matrix are selected to provide a predetermined routability factor. The second family of PLDs has a larger pin to logic ratio than the first family of PLDs.

    摘要: Programmable logic device design software is provided for allocating specific resources in a programmable logic device having a multiplicity of programmable logic blocks interconnected by a programmable switch matrix to logic equations in a user logic design. In particular, a resource allocation means for fitting a logic design to a multiplicity of programmable logic blocks with limited interconnectivity between the modules is provided. The resource allocation means requires minimal programmable logic device resources to achieve the allocation of resources within the programmable logic device to the user logic design. The resource allocation means employs block partitioning means and resource assignment means to map user logic to a programmable logic device (PLD) having multiple programmable AND fixed OR arrays interconnected by a programmable switch matrix, i.e., allocate the PLD resources to the user logic.

    摘要: A dc to ac inverter for operating a gaseous discharge lamp through pre-ignition, arc stabilization, warm-up and final run states is disclosed. The arrangement comprises a transformer and a pair of transistors connected for alternate conduction in a self-oscillating configuration in which turn off occurs at a predetermined flux level in each conduction period. The flux limit is used to preclude excess current drain during warm-up when the lamp resistance is at a minimum. A capacitor is provided, resonant at a harmonic of the inverter output waveform for producing the enhanced output voltage required for pre-ignition. The capacitor also helps to maintain a higher harmonic content during warm-up, enhancing the effective ballasting reactance during that period in relation to that during final run operation. A shift of the oscillating frequency of the inverter from pre-ignition to final run operation further enhances inverter operation.
