摘要: A programmable logic device is presented comprising a global interconnect array whose lines are fed via programmable multiplexers to two stacks of logic array blocks on its sides. The logic array blocks include CMOS look up table based logic modules that consume zero DC power. The global interconnect array lines are fed to the multiplexers in a specific pattern which maximizes routing flexibility and speed. The combination of low power logic array blocks and high performance global interconnect array allows for increased logic density at lower power consumption compared to prior art programmable logic array devices.

摘要: A programmable variable depth and width random-access memory circuit is provided. The memory circuit contains rows and columns of memory cells for storing data. A row decoder is used to address individual rows of the memory cells. Column address circuitry receives a column address signal and a width and depth selection signal. A column decoder within the column address circuitry addresses one or more columns of memory cells of the RAM array based on the selected width of the array. The output of the column decoder is routed to the appropriate column or columns of memory cells by a pattern of fixed connections and a group of programmable multiplexers. The number of data output lines to which data signals are provided is determined by the selected width of the RAM array. The output circuitry contains a group of programmable demultiplexers and a routing array having a pattern of fixed connections suitable for passing data signals from the RAM array to the selected number of data output lines.

摘要: A programmable logic array integrated circuit has a number of programmable logic modules which are grouped together in a plurality of logic array blocks ("LABs"). The LABs are arranged on the circuit in a two dimensional array. A conductor network is provided for interconnecting any logic module with any other logic module. In addition, adjacent or nearby logic modules are connectable to one another for such special purposes as providing a carry chain between logic modules and/or for connecting two or more modules together to provide more complex logic functions without having to make use of the general interconnection network. Another network of so-called fast or universal conductors is provided for distributing widely used logic signals such as clock and clear signals throughout the circuit. Multiplexers can be used in various ways to reduce the number of programmable interconnections required between signal conductors.
