Adaptive Logic Modules
Figure 2–12. Conditional Operation Example
© February 2009 Altera Corporation
The equation for this example is:
R = (X < Y) ? Y : X
To implement this function, the adder is used to subtract Y from X. If X is less than Y,
the carry_out signal is 1. The carry_out signal is fed to an adder where it drives
out to the LAB local interconnect. It then feeds to the LAB-wide syncload signal.
When asserted, syncload selects the syncdata input. In this case, the data Y drives
the syncdata inputs to the registers. If X is greater than or equal to Y, the syncload
signal is de-asserted and X drives the data port of the registers.
The arithmetic mode also offers clock enable, counter enable, synchronous up/down
control, add/subtract control, synchronous clear, and synchronous load. The LAB
local interconnect data inputs generate the clock enable, counter enable, synchronous
up/down, and add/subtract control signals. These control signals are good
candidates for the inputs that are shared between the four LUTs in the ALM. The
synchronous clear and synchronous load options are LAB-wide signals that affect all
registers in the LAB. These signals can also be individually disabled or enabled per
register. The Quartus II software automatically places any registers that are not used
by the counter into other LABs.
