Hello,
I am having difficulties in understanding the connection between the VPIF peripheral and the memory (any available) in the OMAP-L138 processor.
I am having difficulties in understanding the connection between the VPIF peripheral and the memory (any available) in the OMAP-L138 processor.
More particularly,I have two questions (maybe too naive!):
1) I am not sure if the VPIF peripheral is directly connected to memory through a DMA interface as depicted in page 1743 of OMAP-L138 TRM.
1) I am not sure if the VPIF peripheral is directly connected to memory through a DMA interface as depicted in page 1743 of OMAP-L138 TRM.
In other words, if I have allocated in DDR2 two buffers in which I store the incoming frames from the VPIF peripheral.These buffers are filled without the intervention of the ARM/DSP ?
2) Is the EDMA controller used by the VPIF peripheral,or it is just a DMA controller available to the programmer and it is not used by any peripheral that claims to have DMA access.
Thank you in advance!
