1. CRU Weekly Meeting CRU INDIA TEAM 13 th May 2015 PCIe multi-channel DMA Evaluation

2. In Arria 10 we have 4 types of PCI application interface: 1.Avalon-ST 2.Avalon-MM 3.Avalon-MM with DMA 4.Avalon-ST with SR-IOV Objective is to design multi- DMA PCI application interface for Arria 10, by getting motivation from PCI Express Multi-Channel DMA Interface (ug_multich_dma.pdf) available for Stratix-V The PCI express Multi-Channel DMA design uses Avalon-ST with SR-IOV Available IP for PCI in QSYS

3. Detected in Windows after installing Jungo Driver

4. A snapshot from Jungo Driver of Configuration Space

5. Scientific Linux Altera PCIe Detection

6. BAR – Read/write test is successful in windows DMA – Read/Write test is not successful in Altera Linux driver. So, benchmarking can not be done. Read/Write Test

7. Ref: ug_multich_dma.pdfug_multich_dma.pdf Modify the design to meet ALICE requirement

8. Is PCIe SR-IOV support required ? Is CVP over PCIe needed ? The mapping of DMA is one lane per PCIe channel or arbitary? Few Questions
