摘要： A buffer object for performing intelligent buffering functions in a data acquisition (DAQ) system. The buffer object stores information regarding data to be transferred and includes one or more iterators for performing burst transfers. When a DAQ user application generates a call to perform data transfer operations in the DAQ system, the driver level software creates or instantiates a buffer object. The buffer object includes data format information specifying a format of the data being transferred, including the size of the data, the number of samples per scan, and number of scans of the data. The driver level software also creates a foreground iterator which is executable to transfer data between a client portion of system memory and a buffer portion of system memory. The driver level software also creates a background iterator which is executable to transfer data between a buffer portion of system memory and the on-board memory comprised on the DAQ device. The foreground iterator and the background iterator execute in response to the DAQ user application to perform data transfers to/from the DAQ device. The foreground and background iterators also use information in the buffer object to perform the data transfer. In the preferred embodiment, the foreground iterator executes in user mode of the CPU, and the background iterator executes in kernel mode of the CPU.

摘要： A system and method for enabling a graphical program to natively access an external memory buffer are disclosed. The graphical program may execute within a graphical program execution environment, and the external memory buffer may be allocated by another program that executes externally from the graphical program and the graphical program execution environment. The graphical program may be executed concurrently with a producer program that stores data in the memory buffer, and/or with a consumer program that reads and uses the data from the memory buffer. The memory buffer may be located within a region of memory allocated by the producer program, by the consumer program, or by another program that executes externally from the graphical program and the graphical program execution environment, such as a memory manager program.

摘要： A mechanism for managing packetized data transfers in a system including a transmitting and a receiving device. The transmitting device may transmit data to the receiving device in a plurality of packets, each packet a predetermined number of data bytes wide. The transmitting device may include a transfer count unit to maintain a data transfer count based on a number of transmitted data bytes. The receiving device may program the transmitting device with a transfer count mark, which may be a number that corresponds to a specific count of the data transfer count. The transmitting device may calculate a difference between the data transfer count and the transfer count mark. If the difference between the transfer count and the transfer count mark is less than the predetermined number, the transmitting device may transmit a short data packet having less than the predetermined number of data bytes to the receiving device.

摘要： A graphical program execution environment that facilitates communication between a producer program and a consumer program is disclosed. The producer program may store data in a memory block allocated by the producer program. A graphical program may communicate with the producer program to obtain a reference to the memory block. The graphical program may asynchronously pass the reference to the consumer program, e.g., may pass the reference without blocking or waiting while the consumer program accesses the data in the memory block. After the consumer program is finished accessing the data, the consumer program may asynchronously notify the graphical program execution environment to release the memory block. The graphical program execution environment may then notify the producer program that the block of memory is no longer in use so that the producer program can de-allocate or re-use the memory block.
