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
