Double Buffer Mode Principle ∙ | Intel cPCI-7200 specs

The PCI-7200 double buffer mode functions were designed according to the principle described above. If you use _7200_DblBufferMode() to enable double buffer mode, the following _7200_DI_DMA_Start() will perform double-buffered DMA DI. You can call _7200_CheckHalfReady() to check if data in the circular buffer is half-full and ready for copying to the transfer buffer. Then you can call _7200_DblBufferTransfer() to copy data from the ready half buffer to the transfer buffer.

In Win-95 version, W_7200_Alloc_DBDMA_Mem() is needed to allocates a contiguous DMA memory for the circular buffer. The buf_size argument of W_7200_Alloc_DBDMA_Mem() is the half size of circular buffer in byte, that is, the size of each half buffer in byte. The DMA memory is referenced by the return parameter handle. This memory is system memory, users are not allowed to access it directly.
