Data flow control of GLBCE module is done by PCLK. While ACL is high, every PCLK is associated with a pixel data. GLBCE processes the image cycle by cycle, and output the data after certain cycles of latency.
When stall signal (SUS) comes in from CAL output port, switch forwards the stall signal to CAL input port. Upstream CAL port will stop sending data. No flow control is done at switch level or by GLBCE. Therefore, GLBCE block does not have suspend signal input/output.
