发明名称 Method and apparatus for lock synchronization in a microprocessor system
摘要 A method of controlling operations by one or more processors includes granting ownership of a memory location having data stored therein to a first processor and performing, in an atomic manner by the first processor, a read operation to load the data from the memory location to a register, a modify operation to modify the data in the register, and a write operation to store the data from the register to the memory location. The method also prevents other operations directed towards the data by a second processor while the read, modify, and write operations are performed by the first processor, and vice versa. Ownership of the memory location is released after performing the read, modify, and write operations so as to allow the first or second processors to perform subsequent atomic operations.
