Overview
The Reduced Latency Dynamic Random Access Memory (RLDRAM) Controller is a general-purpose memory controller that interfaces with industry standard RLDRAM. The controller can be configured to function as RLDRAM I, RLDRAM II CIO (Common I/O) or RLDRAM II SIO (Separate I/O). The RLDRAM is a high-speed memory device used mainly in high bandwidth, latency sensitive application like communications, data storage etc. Data is transferred on both edges of the clock, doubling the rate of data transfer. This IP provides an interface between the RLDRAM and the generic bus interface.
The RLDRAM controller is designed to support RLDRAM I with target speeds up to 300 MHz DDR and RLDRAM II CIO or SIO modes with target speeds up to 400 MHz DDR.
Note the RLDRAM IP Core is implemented using both MACO ASIC gates and soft logic in the FPGA array. Since a significant portion of the implementation is in MACO, more of the FPGA Array is left for the user.
Software Requirements
* ispLEVER version 7.0 or later
* MACO design kit
* MACO license file

In order to fully capitalize on the benefits of DDR3 memories, it is important to have an efficient and easy to use DDR3 memory interface controller. A video processing application provides a good example of the key requirements of a DDR3 memory system and the features needed from a DDR3 Interface in similar stream-oriented data processing systems.
The union of Microcontroller Unit (MCU) intellectual property (IP) cores with FPGAs provides a far more flexible hardware platform than traditional MCU ASSPs.

In recent years, emerging industries such as AI, Internet of Things, 5G, and intelligent networked vehicles have flourished, and the high requirements for performance have greatly increased the scale and complexity of chips, constantly challenging IP limitations.

DDR is most critical IP to SoC’s successful operation, because processors in SoC typically spends the majority of its cycles on reading and writing to DDR memory.
