ABSTRACT:
A cell selection apparatus includes processing circuits, conversion tables, a selector output reference table, conversion circuits, a discrimination section, a selection section, a registration section, and selector circuits. Each processing circuit performs a predetermined process for each cell. Each conversion table stores cell identifiers and process identifiers. The selector output reference table stores circuit identifiers and discrimination information indicating whether each circuit identifier is valid. Each conversion circuit reads out a cell identifier and a process identifier from the conversion table. The discrimination section discriminates whether a circuit identifier corresponding to the readout cell identifier is valid. The selection section selects one processing circuit corresponding to a process type indicated by the readout process identifier. The registration section registers discrimination information indicating that the circuit identifier indicating the selected processing circuit is valid. Each selector circuit inputs a cell to the selected processing circuit, and also inputs a cell to the processing circuit indicated by the circuit identifier discriminated as a valid identifier.
