About This MegaCore Function
Stratix II and Stratix II GX devices support RLDRAM at up to 300 MHz.
Table 1–4 shows the clock frequency support for Stratix II and Stratix GX
device families, with the Quartus II software.
Table 1–5 shows typical sizes in combinational adaptive look-up tables
(ALUTs) and logic registers for the RLDRAM II controller.
