摘要： Disclosed herein are techniques to manage access to a memory using a buffer construct that includes state information associated with a region of the memory. The disclosed techniques facilitate access to the region of memory through a direct memory access operation while the state information of the buffer construct is in a first state. The state information can be transitioned to a second state in response to a first instruction. The disclosed techniques also facilitate access to the region of memory through a cache operation while the state information of the buffer construct is in the second state is disclosed. The state information can be transitioned to the first state in response to a second instruction.

摘要： A computer system is provided that utilizes a buffer construct to manage memory access operations to a region of memory. The buffer construct may correspond to a data item or structure that represents a region of memory. Each task may control the buffer construct exclusively of other tasks, so that the region of memory that is represented by the buffer construct is only available to the controlling task. Another task that requires access to the region of memory must wait until the controlling task makes the buffer construct available. The controlling task makes the buffer construct available only when DMA or other memory access operations that are in progress become complete. In this way, the buffer construct acts as a token that synchronizes each of the concurrent tasks execution and ensures mutually exclusive access to the common region of memory.

摘要： A concurrent and asynchronous system may be managed by monitoring the performance of a plurality of operations that access a designated region of memory. In that region of memory, an occurrence of a potentially non-deterministic event can be detected when at least one of the operations is a write operation. The occurrence of the potentially non-deterministic event may then be recorded.

摘要： In an embodiment, buffer constructs may be generated to be associated with any one of multiple mutually exclusive states, including an open state and a closed state. When the buffer construct is in the closed state, the region of memory represented by the buffer construct is made accessible to one or more direct memory access (DMA) operations. Upon completion of the one or more DMA operations, the buffer construct transitions from the closed state to the open state. The region of memory represented by the buffer construct is made accessible for use with one or more cache operations when the buffer construct is in the open state, so that the one or more cache operations are not in conflict with the one or more DMA operations.
