MIPI DSI-2 Controller The Northwest Logic DSI-2 Controller Core is Rambus second generation DSI controller core. It is further optimized for high performance, low power and small size.
It is available in 64 and 32 bit core widths. The 64 bit core width can support 1-8 D-PHY data lanes (8 bit PPI) and 1-4 CPHY lanes (16 bit PPI). The 32 bit core width an support 1-4 DPHY data lanes (8 bit PPI) and 1-2 C-PHY lanes (16 bit PPI) The core implements all three layers defined by the DSI-2 standard: Pixel to Byte Packing, Low Level Protocol, and Lane Management and is fully compliant with the DSI-2 standard. Separate Host (Tx) and Peripheral (Rx) versions of the core are provided.
PCI Express 4.0/3.0/2.1/1.1 Support The Northwest Logic Expresso 4.0 Core is part of Rambus’ PCI Express Solution. This solution is designed to achieve maximum PCI Express throughput while being easy to use.
The Expresso 4.0 Core separately, or in combination with Northwest Logic family of DMA Cores and DMA Drivers, provide the maximum system throughput on a PCI Express link. Contact Rambus for more details.
The core is specifically designed for ease of use including full receive packet decoding, complete error handling, automatic handling of PCI Express message packets and comprehensive system-debug and link monitoring support.
The core is delivered fully integrated and verified with the user’s Target PHY. Contact Rambus for a complete list of supported PHYs. To accelerate simulations, the core is also delivered integrated with a fast-simulating behavioral PHY.
High-performance PCIe-AXI Bridge and/or scatter-gather DMA The Northwest Logic Expresso DMA Bridge Core from Rambus provides high-performance DMA and/or bridging between PCI Express and AXI for both Endpoint and Root Port applications.
Key features include:
DMA operation
hard cores
• Supports memory-mapped/streaming (FIFO) DMA operation
• Can be configured with multiple DMA Channels which are
independently controlled by software
• Supports legacy, MSI, MSI-X and local AXI interrupts
Using the core eliminates the need for the user to implement
their own DMA and/or bridging design thus significantly reducing
development time and risk.

Multi-Port Front-End The Northwest Logic Multi-Port Front-End Core from Rambus provides a multi-port interface to Northwest Logic Memory Controller Cores.
Each user request is provided with its own request priority.
The arbiter selects requests based on priority and then round
robin arbitration. The arbiter can also perform Quality Of Service
(QOS) based arbitration. In this mode, the arbitration
results in each port receiving a specified amount of memory
bandwidth. Each port also has a programmable time out period.
Once a request times out, its priority is raised to the highest
level ensuring its quick execution.
The Multi-Port Front-End Core includes the Multi-Burst Core. It
