PLDA: Two vDMA Engine IP Solutions

PLDA announced two DMA engine solutions designed to manage large and heterogeneous data traffic across a PCIe link or across an AMBA AXI fabric solution.

These company’s IP products are a streamlined solution that delivers performance and is easy to integrate into design planning.

The explosion in data traffic due to the advent of AI, ML, automotive and IoT has prompted the development of SoC architectures. They allow system developers to build high-performance applications that can ingest and process amounts of heterogeneous data. In order to take advantage of these architectures, some SoCs integrate a large number of processing elements and require a scalable solution for moving data across computing elements or across a PCIe-attached host platform. In order to meet these needs, PLDA has developed a high-performance DMA Engine available in two versions: As a standalone vDMA engine IP with AMBA-AXI interconnect or as a PCIe 5.0 IP controller with integrated vDMA engine.

VDMA-AXI

VDMA-AXI:
This standalone vDMA-AXI IP product is a centralized AMBA AXI DMA for SoCs that integrate a large number of processing elements and require a scalable solution for moving data across these computing elements. vDMA-AXI is suited for applications in AI, ML and automotive spaces and delivers:

• Up to 2048 DMA channels

• Up to 512 VMs or domains

• Configurable AMBA AXI3/4 interface with either a 256-bit or 512-bit data path

• Up to 128 read and write requests

XpressRICH-AXI controller IP for PCIe 5.0

XpressRICH5-AXI:
This PCIe 5.0 controller IP with built-in vDMA engine is designed for applications that require performance and flexibility for moving data across a PCIe-attached host platform, whether virtualized or not. XpressRICH5-AXI with vDMA is suited for applications in cloud computing, HPC, AI, ML, storage, and networking.

In addition to the features outlined in the standalone vDMA engine, XpressRICH5-AXI also delivers:

• Support for x16, x8, x4, x2, x1 at PCIe Gen5, Gen4, Gen3, Gen2, and Gen1 speeds

• Compliance with PCI-SIG Single-Root I/O Virtualization (SR-IOV) Specification

• Support for Endpoint, Root-Port, and Dual-mode configurations

• Support for up to 32 Physical Functions and 512 Virtual Functions

According to Arnaud Schleich, CEO, PLDA, “New applications and the ever-growing quest for bandwidth is driving a need for faster I/O combined with a flexible design. PLDA’s vDMA solutions provide the performance needed by higher end applications with an ease-of-integration that delivers silicon success.“
