Description of the data path

Frame memory

Normally, an image is captured and transported in consecutive steps. The image
is taken, read out from the sensor, digitized and sent over the Gigabit Ethernet
network.

Manta cameras are equipped with a RAM. Table 42 on page 130 shows how many
frames can be stored by each model.

The memory operates according to the FIFO (first in, first out) principle. This
makes addressing for individual images unnecessary.

Note

The number of frames (StreamHoldCapacity) depends on reso-
lution and pixel format. Listed number of frames is typical for
full resolution and Mono8/Bayer8.
