产品详情资料

 DMA VMEbus所有权DGCS寄存器中的两个字段确定DMA将如何与Universe II中的其他两个潜在主机（PCI目标信道和中断信道）以及总线上的其他VMEbus主机共享VMEbus。这些字段是：VON和VOFF。VON会影响DMA在给另一个主机（Universe II或外部主机）拥有总线所有权之前将传输多少数据。VON计数器用于在传输编程字节数（256字节、512字节、1K、2K、4K、8K或16K）后暂时停止DMA传输数据。当在VMEbus上执行MBLT传输时，DMA将在达到编程VON限制后的2048字节内停止执行传输。当不执行MBLT传输时，一旦达到编程限制，DMA将在256字节内停止执行传输。当编程为“完成时释放”操作时，当VON计数器达到其编程极限时，Universe II将执行BBSY*的早期释放。可以通过将字段设置为零来禁用VON。当设置为这样时，DMA将继续传输数据，只要它能够。DMA可以在其他条件下放弃总线所有权。VOFF影响DMA在达到VON限制后重新请求总线之前等待的时间。DMA VMEbus Ownership Two fields in the DGCS register determine how the DMA will share the VMEbus with the other two potential masters in the Universe II (PCI Target Channel, and Interrupt Channel), and with other VMEbus masters on the bus. These fields are: VON and VOFF. VON affects how much data the DMA will transfer before giving the opportunity to another master (either the Universe II or an external master) to assume ownership of the bus. The VON counter is used to temporarily stop the DMA from transferring data once a programmed number of bytes have been transferred (256 bytes, 512 bytes,1K, 2K, 4K, 8K, or 16K). When performing MBLT transfers on the VMEbus, the DMA will stop performing transfers within 2048 bytes after the programmed VON limit has been reached. When not performing MBLT transfers, the DMA will stop performing transfers within 256 bytes once the programmed limit has been reached. When programmed for Release-When-Done operation, the Universe II will perform an early release of BBSY* when the VON counter reaches its programmed limit. VON may be disabled by setting the field to zero. When set as such, the DMA will continue transferring data as long as it is able. There are other conditions under which the DMA may relinquish bus ownership. VOFF affects how long the DMA will wait before re-requesting the bus after the VON limit has been reached.
