embedded multiplier block

A feature of supported device Cyclone® IV families devices that is optimized for multiplier-intensive low-cost DSP applications.

Each supported device Cyclone® IV has one to three columns of embedded multipliers that implement multiplication functions.

Each embedded multiplier consists of the following elements:

  • Multiplier stage
  • Input and output registers
  • Input and output interfaces

Each embedded multiplier can be used in one of two operational modes, depending on the application needs:

  • One 18-bit multiplier
  • Up to two 9-bit independent multipliers
