  • Integrated circuit, method of circuit configuration and program thereof
    Patent number: 6768337
    Abstract: A plurality of circuit cells, a plurality of matrix switch sections and a plurality of switch sections for connecting between the plurality of circuit cells, all of which form a part of a circuit cell array, and a plurality of input/output cell sections arranged around the circuit cell array all change their circuit configurations in accordance with a configuration data to be supplied. In some of these circuit blocks, at least a part of the circuit thereof is fixed at a predetermined circuit configuration, and a conversion of the configuration data based on proprietary information regarding the fixed circuit is performed at a supplier of the configuration data. Thus, a differential configuration data for portions of the circuit other than the fixed circuit portion is generated and supplied to the integrated circuit.
