1. Logic Array Blocks and Adaptive Logic Modules in Cyclone® V Devices

This chapter describes the features of the logic array block (LAB) in the Cyclone® V core fabric.

The LAB is composed of basic building blocks known as adaptive logic modules (ALMs) that you can configure to implement logic functions, arithmetic functions, and register functions.

You can use a quarter of the available LABs in the Cyclone® V devices as a memory LAB (MLAB).

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
