Abstract: A first processing core selects a first memory address of a first memory area based on a last written buffer that identifies a last written memory address. The first memory area is a portion of a shared memory, and the first processing core has sole write access to the first memory area among a plurality of processing cores that use the shared memory. Data is written to the first memory address of the first memory area. After writing the data to the first memory address, the last written buffer is updated to designate the first memory address as the last written memory address of the first memory area. A second processing core of the plurality of processing cores is operable to access the data by accessing the last written buffer and determining, based on the last written buffer, that the data is stored at the first memory address.
