Abstract: A register management system is coupled to a register. The register management system receives an address and functional data for a write operation to be performed on the register. The functional data includes write bits and mask bits associated with the write bits. One or more mask bits having a first logic state indicate that associated one or more write bits are to be written to the register, respectively. Based on the address, the register management system selects a first half of the register or a second half of the register to perform the write operation. Further, the register management system writes the one or more write bits associated with the one or more mask bits having the first logic state to one or more storage elements of the first half of the register or the second half of the register, respectively.

Abstract: A multi-clock domain system includes a synchronizer circuit. The synchronizer circuit includes a sequential logic circuit and a synchronizing stage. The sequential logic circuit receives a functional signal that is generated based on a first clock signal that is further associated with a first clock domain, a second clock signal that is associated with a second clock domain, and a reference signal. Based on the first and second clock signals and the reference signal, the synchronizer circuit outputs a logic signal. When the functional signal is activated, the logic signal is activated and remains activated for a predetermined time duration after the functional signal is deactivated. The synchronizing stage receives the second clock signal and further receives the logic signal from the sequential logic circuit, and outputs a synchronized functional signal.

Abstract: A system for synchronizing a functional reset between first and second clock domains that operate on first and second clock signals, respectively. The system includes first, second and third synchronizer flip-flops that operate on the second clock signal. The first synchronizer flip-flop receives a functional reset signal generated by the first clock domain at its reset terminal and generates a low output signal. The low output signal causes the second synchronizer flip-flop and subsequently the third synchronizer flip-flop to generate low output signals at positive edges of the second clock signal. The low output signal generated by the third synchronizer flip-flop is used to reset the second clock domain.
