Cycle:
*A* Queue 9 of Device 1 is selected for read operations. The
OV is currently being driven by Device 2, a queue within device 2 is selected for reads. Device 2 also has control
of Qout bus, its Qout outputs are in Low-Impedance. This diagram only shows the Qout outputs of device 1. (Reads are disabled).
*B* Reads are now enabled. A word from the previously selected queue of Device 2 will be read out.
*C* The Qout of Device 1 goes to Low-Impedance and word Wd is read from Q9 of D1. This happens to be the last word of Q9. Device 2 places its Qout outputs into
High-Impedance, device 1 has control of the Qout bus. The
OV flag of Device 2 goes to High-Impedance and Device 1 takes control of OV. The OV flag of Device 1 goes LOW
to show that Wd of Q9 is valid.
*D* Queue 15 of device 1 is selected for read operations. The last word of Q9 was read on the previous cycle, therefore
OV goes HIGH to indicate that the data on the Qout is
not valid (Q9 was read to empty). Word, Wd remains on the output bus.
*E* The last word of Q9 remains on the Qout bus,
OV is HIGH, indicating that this word has been previously read.
*F* The next word (We-1), available from the newly selected queue, Q15 of device 1 is now read out. This will occur regardless of
REN, 2 RCLK cycles after queue selection
due to the FWFT operation. The
OV flag now goes LOW to indicate that this word is valid.
*G* The last word, We is read from Q15, this queue is now empty.
*H* The
OV flag goes HIGH to indicate that Q15 was read to empty on the previous cycle.
*I* Due to a write operation the
OV flag goes LOW and data word W0 is read from Q15. The latency is: tSKEW1 + 1*RCLK + tROV.
