Abstract: A computer system has a memory configured for sharing data between a first application and a second application. The memory includes a metadata region and a data region. The metadata region includes metadata that indicates how data being communicated between the first application and the second application is to be interpreted. The metadata also indicates whether the data can be found in the metadata itself or in a particular location in the data region. Each application can be assigned its own memory location containing a flag that can be set in order to indicate to the other application that the memory is ready to be accessed by the other application. The memory location can be implemented using a hardware register or in memory, either the same memory that includes the metadata and data regions or on a separate memory.
