Twister DDR-SDRAM Evaluation Kit From FPGA

from FPGA

Twister is an evaluation board for exploring double data rate (DDR) SDRAM memory along with Altera's low-cost Cyclone®  devices. This evaluation kit is ideal for existing Nios® embedded processor users, kit owners, and developers who require additional memory bandwidth or intend to use low-cost DDR memories. The board is designed to support the maximum Cyclone DDR SDRAM data bandwidth. Besides the Altera® Cyclone device there is also an Altera MAX® device on the board that acts as a configuration controller. You can easily expand the Twister board by mounting daughter boards, such as FPGA's Lancelot VGA board, onto the Twister expansion interface. Twister is shipped with a DDR SDRAM reference design for Altera's Nios embedded processor.
