Classification: CPC H  G | IPC G  H

Claim 0:
1. A programmable integrated circuit (IC) comprising:
a static region of programmable circuitry; and
a dynamic region of programmable circuitry, the dynamic region comprising a plurality of partial reconfiguration (PR) regions, each PR region being capable of supporting one or more user-specified circuits, wherein the programmable IC is configured to:
send a first message to a host, indicating that a modification of at least a first user-specified circuit in a first PR region of the plurality of PR regions will occur;
cause a memory to clear and release one or more memory resources related to the first user-specified circuit and to effectively ignore requests from the first PR region, while allowing at least one of:
other memory resources related to other user-specified circuits to operate; or
accesses to the memory from other PR regions; and

modify the at least the first user-specified circuit in the first PR region.
