Abstract
Techniques and circuitry are used to more rapidly configuring programmable integrated circuits. Configuration data is input into a programmable integrated circuit in parallel via parallel inputs ( ), and this data is also handled internally in parallel. The configuration data will be stored in a data register ( ). This data register is segmented into two or more segments, each segment being made up of a serial chain of registers ( ). The configuration data is input into the two of more segments of the data registers in parallel. Circuitry is also provided to handle redundancy.
