Hello,

In the block diagram of the manual of ArduCAM-Mini-5MP-Plus OV5642 Camera Module there is “frame buffer FSM” within ArduChip and “Off-chip Memory”. What is the difference? Which one is 8MB SDRAM? What is the memory size of “frame buffer FSM”?

Thank you

Hi,

Frame Buffer FSM, ArduChip’s on-chip buffer (internal FIFO), used for frame processing, has a small capacity, divided into read buffer and write buffer, 1kB each.
Off-chip Memory, ArduChip’s off-chip cache (external SDRAM), has a much larger capacity than the on-chip cache, 8MB, which can cache multiple frames of data.
