1.5. Adaptive Logic Module
Arria® V devices use a 28 nm ALM as the basic building block of the logic fabric.
The ALM, as shown in following figure, uses an 8-input fracturable look-up table (LUT) with four dedicated registers to help improve timing closure in register-rich designs and achieve an even higher design packing capability than previous generations.
You can configure up to 50% of the ALMs in the Arria® V devices as distributed memory using MLABs.
