ref. design of S10 with a PCIe enabled 256-bit bursting slave interface (HPTXS) Port

Hello all, 

 

please suggest me a reference design on stratix 10 board with a PCIe , enabled high performance burst interface (HPTXS) port of 256 bit width.  

I searched on the net to have a clear understanding about this port, but not found anything. yes, there are 2 paras of information available on the user-guide that available from the tool, but didn't understood anything. 

 

someone please send me a link to understand the functionality of that port, referral design. 

 

 

some questions  

1. can i enable this HPTXS port irrespective of "enable DMA" option that is used to do dma transfers from host to fpga ? 

2. once i enable this HPTXS port , i have to select - no. of pages and size of each page (on what basis should i select these two parameters) ? 

 

Regards, 

Anil

Refer Session 7.2.1.2 https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/ug_s10_pcie_avmm.pdf 

(address + 32 * burst count) <= (page base address + page size ) 

 

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
