Enhanced Universal DDR Memory and Protocol Controllers

The 草榴社区 Enhanced Universal DDR Controllers consist of two high-performance products: the Enhanced Universal DDR Memory Controller (uMCTL2), and the Enhanced Universal DDR Protocol Controller (uPCTL2). Both products support the JEDEC DDR4, DDR3, DDR2, Mobile DDR, LPDDR4, LPDDR3, and LPDDR4 SDRAM standards and AMBA AXI3/AXI4 and native on-chip busses. Both products have extensive features for low power and high Reliability, Availability and Serviceability (RAS).

The uMCTL2 Memory Controller incorporates a scheduler and optional arbiter to serve memory requests from 1-16 application-side host ports with high bandwidth and low latency that is managed by Quality of Service (QoS) mechanisms.

The uPCTL2 Protocol Controller serves the needs of applications where scheduling is done in the interconnect or elsewhere on the host side, providing low latency and in-order command execution.

All the 草榴社区 Universal controllers connect to PHYs via the industry-standard DFI interface, and all their registers may be accessed through industry-standard APB busses.
