On-Chip Memory Size

Dear Friend's, 

 

What is the maximum size of On -Chip Memory or up to what extend we go up to increase its size. 

 

i am using Cyclone-III device , i have altera Embedded Development Board. and i have Quartus 11 SP2 Tool. 

 

I have add the On-Chip memory in my SOPC Builder, now what is the maximum size of this memory. or if i increase the on-chip memory size does it effect the other component like TSE_MAC FIFO etc. or if i want to increase on-chip memory size i have to decrease the other component memory. 

 

 

With regards

It depends on the fpga part.

Whether any particular value will 'work' depends on the available memory on the part, and the number of memory blocks needed by other items on the fpga. 

 

If you try to use every last memory block then it is likely to limit the maximum speed due to long 'tracks'. 

 

I think the database server gets reloaded every morning just before 9am UTC.
