Honored ContributorConfigure Cyclone with Flash and PIC
Hi @ all!
Has anyone tried to configure Cyclone on bootup wit a simple 8-Bit-µC? Is there an example available ? I've seen some posts in different forums about a CPLD-solution, but no example for Altera. How much will a CPLD solution cost? ASD is not possible, because I've different configurations for the Cyclone.3 Replies
Altera_ForumFor a Cyclone EP1C20, the config file size is 3.56 M-bits.
The maximum DCLK frequency Cyclone supports is 66 MHz; so 1/66M * 3.56 M-bit = 54ms This does not take into account any overhead in the code, as well as the fact that your 8-bit micro probably can't toggle it's GPIO at 66 MHz..... Hope this helps.- Altera_Forum
Thank's first!
Do anyone have experience how long it need's to configure a 20k LE's Cyclone Device with PS. Doku say's only: Moderate. What is moderate? 1ms, 100ms, 1s, 10s? - Altera_Forum
Greetings,
Look for the MicroRunner here: http://www.altera.com/support/devices/configuration/cfg-solutions.html You can run this code on any micro and config your FPGA via PS mode.
