Abstract
In a system where data is shared by a first module writing the information to memory, and a second module then reading the information from the memory, asynchronous and/or unpredictable operation of the two modules may lead to instances of blocking and/or instances of the second module reading invalid data from the memory. Aspects of the present disclosure manage reads and writes to memory such that blocking by either the first module and/or the second module, and/or reads of invalid data by the second module, may be prevented if so desired.
