Fig 1 shows the main modules of the DDR3 SDRAM reference design: user back-end interface, command, address and data FIFOs, main memory controller, initialization controller, calibration logic, and I/O ...

Writing an SDRAM controller from scratch isn’t for the fainthearted – first of all you really have to know how SDRAM works (RAS, CAS, precharges, refresh cycles), and because of the high speed ...

DDR SDRAM CONTROLLER IP In this section it will be introduced the main characteristics of DDR memory and controller. Double data rate memories contain three buses: a data bus, an address and a command ...

Synchronous DRAM (SDRAM) becomes the memory of choice due to its speed, burst access and pipeline features. A controller is required to provide proper commands for SDRAM initialization, read/write ...

The DDR SDRAM controller IP core for LatticeECP and LatticeEC FPGA families features programmable burst lengths of 2, 4, or 8; CAS latency of two or three cycles; intelligent bank management; as many ...

Partnering with Altera, the company has introduced a double-data rate (DDR) SDRAM controller capable of performing control functions at up to 266 MHz when implemented into the company's EP20K400E ...

Now-a-days, DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory) has become the most popular class of memory used in computers due to its high speed, burst access and pipeline ...

It's been a space since I've posted here, but I've run into a baffling problem and need some ideas. We're designing an SDRAM controller as part of an EE project and we can't seem to get the data ...

– a 16KB direct mapped cache to hide the SDRAM latency, using the FPGA internal block RAM – a UART interface for external communications He also ported CP/M-2.2, MP/M-II and UZI (a UNIX system ...

The company has announced what it is calling the industry’s first 533-Mb/s DDR2 SDRAM controller IP core supporting the LatticeECP2/ECP2M low-cost FPGA families, and the high- ...
