Abstract
Integrated circuits may include partial reconfiguration (PR) circuitry for reconfiguring a portion of a memory array. The PR circuitry may include a host circuit, a control circuit, an address register, and first, second, and third data registers. The host circuit may send a series of PR instructions to the control circuit. The control circuit may include a decompression circuit for decompressing compressed instructions, a decryption circuit for decrypting encrypted instructions, an error checking circuit for detecting errors in the instructions, and a logic circuit. The address register may select a desired frame. The selected frame may be loaded into the third data register. The contents of the third data register may be shifted into the first data register. The contents of the first data register may be modified according to a desired logic function using the logic circuit, shifted into the second data register, and written into the selected frame.
