Classification: CPC H  G | IPC G  H

Claim 5:
6. A method of dynamic modification, comprising:
sending a first message, from a programmable integrated circuit (IC) to a host, indicating that a modification of at least a first user-specified circuit in a first partial reconfiguration (PR) region will occur, the programmable IC comprising:
a static region of programmable circuitry; and
a dynamic region of programmable circuitry, the dynamic region comprising a plurality of PR regions including the first PR region, each PR region being capable of supporting one or more user-specified circuits;

causing 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

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