Cycle:
*A* Queue 12 of Device 1 is selected on the read port. A queue within Device 2 had previously been selected. The
PAE flag output and the data outputs of device 1 are High-Impedance.
*B* No read occurs.
*C* The
PAE flag output now switches to device 1. Word, Wn is read from Q12 due to the FWFT operation. This read operation from Q12 is at the almost empty boundary, therefore
PAE will go LOW 2 RCLK cycles later.
*D* Q15 of device 1 is selected.
*E* The
PAE flag goes LOW due to the read from Q12 2 RCLK cycles earlier. Word Wn+1 is read out due to the FWFT operation.
*F* Word, W0 is read from Q15 due to the FWFT operation. The
PAE flag goes HIGH to show that Q15 is not almost empty.
NOTE:
1. The waveform here shows the
PAE flag operation when no queue switches are occurring and a queue selected on both the write and read ports is being written to then read
from at the almost empty boundary.
Flag Latencies:
Assertion: 2*RCLK + tRAE
De-assertion: tSKEW2 + RCLK + tRAE
If tSKEW2 is violated there will be one extra RCLK cycle.
