The burst size can be programmed to 1, 4, 8, 16, or 256 words using DMA_Config [amba_burst_length] register bit. The AXI DMA controller always uses INCR type accesses. When performing data transfers, the burst length used can be programmed using bits [4:0] of the DMA configuration ...
Q1: I configured the Maximum Avalon-MM burst length=1024 of the avalon bus in the DDR3 IP Core. In the actual test, I found that if the read burst length is less than 8 (8 or 4), I can correctly write and Read the data(Fig1), but when the read burst le...
Currently, I want to store video data by storing the pixel data in the arbitrary memory address then read it back and output to the display device (monitor through HDMI interface). The reading interface from SDRAM used burst length of 32bytes. If I increase the writing ...

Tom Johnson 162147 年多前in reply toYordan Kovachev Li, Proper DDR operation requires proper board design validation. The lengths in the PHY CALC worksheet appear unusual. Please provide a track length matching report that was used to validate your layout. Additional guidance ...
If you are using the memory controller in a stand alone fashion with an Avalon-MM local interface, you should strobe the burst begin even if you drive a burst length of 1 into the memory controller. Also the burstbegin signal does not heed waitrequest (local_ready == 0) so if the memo...
