10. External Memory Interface in Agilex™ 3 FPGAs and SoCs
The Agilex™ 3 FPGAs and SoCs feature a substantial external memory bandwidth. This bandwidth is accompanied by the ease-of-design, lower power, and resource efficiencies of high-performance hard memory controllers. Using the hard or soft memory controller, you can configure external memory interfaces width up to a maximum of 32 bits.
Figure 7. Hard Memory Controller
Each I/O bank contains 96 general purpose I/Os and two high-efficiency hard memory controllers. The hard memory controllers support various memory types, each with different performance capabilities. You can bypass the hard memory controller and implement a soft memory controller in user logic.
Each I/O contains a hard DDR read and write path (PHY) capable of performing key memory interface functions such as:
- Read and write leveling
- FIFO buffering to lower latency and improve margin
- Timing calibration
- On-chip termination
Hard microcontrollers aid the timing calibration. Altera customized these hard microcontrollers to control the calibration of multiple memory interfaces. The calibration enables the Agilex™ 3 device to compensate for process, voltage, and temperature (PVT) variance within the Agilex™ 3 device or the external memory device. The advanced calibration algorithms ensure maximum bandwidth and robust timing margin across all operating conditions.
