1. Logic Array Blocks and Adaptive Logic Modules in Intel® Arria® 10 Devices

The logic array block (LAB) is composed of basic building blocks known as adaptive logic modules (ALMs). You can configure the LABs to implement logic functions, arithmetic functions, and register functions.

You can use a quarter of the available LABs in the Intel® Arria® 10 devices as a memory LAB (MLAB). Certain devices may have higher MLAB ratio.

The Intel® Quartus® Prime software and other supported third-party synthesis tools, in conjunction with parameterized functions such as the library of parameterized modules (LPM), automatically choose the appropriate mode for common functions such as counters, adders, subtractors, and arithmetic functions.

This chapter contains the following sections:

  • LAB
  • ALM Operating Modes
