Hello All,
I have a question regarding possible limitations of the frame buffer size the SGX530 core is able to handle.
For a new product we are looking into using the AM387x. It's main task will be rendering a 2D vector graphics for a video based product. The AM387x will be interfacing with an fpga using PCIe, the FPGA will contain both the frame buffer for the video as well as the graphics overlay. The video I/O is handled by the fpga, so the AM387x is mainly used for rendering (and some low prio other stuff).
Question: Can the SGX530 core render on a frame buffer (through MMU either on the AM387x DDR or fpga frame buffer) that is larger then 2k x 2k? Our intended max resolution will be 4096x2160.
Please note that the SGX530 will NOT have to render 60 fps, a couple of screen updates per second will be fine for our purposes. Neither will it have to render the entire surface.
I've tried the search function of the forum but was unable to find related threads. The technical reference manual (http://www.ti.com/lit/ug/sprugz7/sprugz7.pdf) is somewhat concerning: In the section handling 3d on page 165 there is a max frame buffer limitation of 2k x 2k. I wonder if this only limits the 3d rendering?
Kind regards,
Egwin Wesselink
