Arria 10 GX Remote Update Circuitry
Hello, We are using an 10AX066 FPGA connected to an MT25QU01 flash. It's connected through Active Serial. We are looking to use a system setup that will allow us to boot into a user image, before falling back to a factory image if it fails to configure 3 times, we do not need a watchdog, or the AnF bits. Is the default behaviour of the Arria 10 device to provide the features provided in this flow chat (https://www.intel.com/content/www/us/en/docs/programmable/683461/current/configuration-sequence-in-the-remote.html)? Is the Remote Update IP core necessary for any functions that we want?
IC FPGA - EP4CE40F23C8N -Urgent
IC FPGA - EP4CE40F23C8N has a maximum number of single-ended digital inputs/ outputs of greater than 700 where in this context, the maximum number of digital inputs/outputs is also referred to as the maximum user inputs/ outputs or maximum available inputs/outputs, whether the integrated circuit is packaged or bare die.
MAXII CPLD VGA CONTROLLER QUESTIONS
Hi there! Im doing some experiment with vga under epm570t100 for 640x480 vga controller, apparently all is quite functional per results on vga screen, however i would like any comments from your expert experience... :D. Design and simulation files attached for your reference or use. My first approach is interfacing controller with 16kx32 sram and shift each 16 bits in memory as individual pixels (black or white). 1-When interface either 16/8bit data bus i find horizontal frame barely can fit the bits(pixels), on my design, last shifted pixel at the rising edge of 25MHz clock_enable signal is just at the end of horixontal line, it is on the falling edge of the video active region... almost a glitch Per screen results when playing with first/last pixel with external switch on data bus, it appears to eat those pixels well... (3 pixels on 1920 screen resolution equivalent to 1 pixel on 640): Is this behavior to be expected?, maybe some designs extend a little the horizontal active region to fit pixels? 2-I find 2 port srams quite attractive for this application, since can write and read independently, u can see here an example of 16bits x32k one. The question is... if two cheaper one port sram is to be used, have u any experience how to manage ping-pong buffering between 2 single port stams like this one? Ie: using vsync or video enable signal to command a switch between 2 rams, one being filled the other being read.... Have u any experience on this one? Thanks in advance! Some extra photos for fun :D: All 16bits "on" 3/4 bits off all off alternated Board
