Guideline: Control Clocking to Reduce Power Consumption
Reduce AC power consumption in your design by controlling the clocking of each memory block:
• Use the read-enable signal to ensure that read operations occur only when necessary. If your design does
not require read-during-write, you can reduce your power consumption by deasserting the read-enable
signal during write operations, or during the period when no memory operations occur.
• Use the Quartus II software to automatically place any unused memory blocks in low-power mode to
reduce static power.
