Abstract
A configuration state memory is associated with a configurable functional block on a reconfigurable chip. The configuration state memory stores more than one configuration for the functional block. This allows the functional block to switch configurations without requiring the configuration data to be loaded from off-chip which would stall the operation of the reconfigurable chip. In a preferred embodiment, the configuration state memory uses a relatively few address bits to produce a relatively broad configuration output to the functional blocks. The small number of input address bits allows the configuration state memory to be addressed by relatively small state machine unit.
