memory allocation functions in vhdl ?

Altera_Forum · ‎06-20-2011

Hi..

I am new to vhdl. Currently I am trying to access ram in DE1 for my project.I need to efficiently allocate data in ram and simultaneously process it and then write it to a file.

I think a function like malloc in C would serve my purpose.Are there any functions in vhdl like this ??Kindly help me.

Thanks.

Is it a RAM shared between a VHDL component and a CPU? In that case you need to do the allocation on the software side with a malloc() call and then give the address to your vhdl component.

If the RAM is only used by your VHDL component then allocation in the malloc() way doesn't exist and you'll have to do it yourself.
