Altera memory controller intellectual property (IP) solutions are hardware-tested, drop-in design blocks that greatly simplify the local interface to complex memory devices such as double data rate (DDR) and single data rate (SDR) SDRAM, quad data rate (QDR) SRAM, zero-bus turnaround (ZBT) SRAM, and FCRAM. Altera solutions include both licensable IP functions and no-cost, open source design examples. The Altera Stratix™, Stratix GX, and Cyclone™ FPGA families include special I/O features designed specifically for interfacing with external memory devices. These features may include dedicated delay paths for data strobe signal alignment, multiple I/O registers to support DDR data transmission, and delay elements to reduce bus contention for ZBT protocols. 显示查询结果31项中的第1 - 10项Megafunction [列出全部31项结果] 下10项 >> Megafunction名称 供应商 PDF 免费评估 认证 支持的器件系列 DDR SDRAM Controller Altera Corporation 试用 OpenCore Plus SOPC Builder Ready, I-Tested Stratix II GX, HardCopy II, Cyclone II, Stratix II, Cyclone, Stratix, Stratix GX DDR SDRAM High Performance Controller Altera Corporation 试用 OpenCore Plus SOPC Builder Ready, I-Tested Stratix IV, Stratix III, Cyclone III, Stratix II GX, Arria GX, HardCopy II, Stratix II DDR2 SDRAM Controller Altera Corporation 试用 OpenCore Plus SOPC Builder Ready, I-Tested Stratix II GX, HardCopy II, Cyclone II, Stratix II, Cyclone, Stratix, Stratix GX DDR2 SDRAM High Performance Controller Altera Corporation 试用 OpenCore Plus SOPC Builder Ready, I-Tested Stratix IV, Stratix III, Cyclone III, Stratix II GX, Arria GX, HardCopy II, Stratix II DDR3 SDRAM High Performance Controller Altera Corporation 试用 OpenCore Plus SOPC Builder Ready Stratix IV, Stratix III QDRII SRAM Controller Altera Corporation 试用 OpenCore Plus I-Tested Stratix II GX, HardCopy II, Stratix II, Stratix, Stratix GX RLDRAM II Controller Altera Corporation 试用 OpenCore Plus I-Tested Stratix II GX, HardCopy II, Stratix II EP550 SDIO / SD memory / MMC Host Controller Eureka Technology Inc. 试用 OpenCore AMPP Approved Cyclone III, Stratix II GX, Arria GX, HardCopy II, Cyclone II, Stratix II, Cyclone, Stratix EP560 SDIO / SD Memory Slave Controller Eureka Technology Inc. 试用 OpenCore AMPP Approved Cyclone III, Stratix II GX, Arria GX, HardCopy II, Cyclone II, Stratix II, Cyclone, Stratix EP560 SDIO / SD Memory Slave Controller Eureka Technology Inc. 试用 OpenCore AMPP Approved Cyclone III, Stratix II GX, Arria GX, HardCopy II, Cyclone II, Stratix II, Cyclone, Stratix [列出全部31结果] 下10项 >> 给本页评分
