Altera's External Memory Interface Solutions Center

Altera's complete memory interface design solutions address today's high-speed memory interface challenges. Specifically, Altera provides solutions for the memory controller with our high-performance memory controller II (HPMCII), our universal memory PHY (UNIPHY), and our hardened memory interface controller (HMC which includes the controller, PHY and multiported front end (MPFFE)). These solutions support error correction codes (ECC).

Altera's solutions are provided as either advanced device architectures, customizable MegaCore^® functions, Quartus^® II design software, reference designs, demonstration boards, and/or simulation models. All of which are accompanied by a rich set of technical documentation.

The Board Skew Parameter Tool (XLS) enables easy and precise board skew parameter calculations while saving crucial design time.

Table 1 lists external memory interfaces supported by Altera FPGAs and HardCopy^® ASICs. Get more information using our External Memory Interface Spec Estimator.
