how to optimize resource usage in HDL coder ?

hi,

I build a model and have a very high usage of the resource. I would like to decrease it, please suggest me what steps can I take for the same? The project is attached and I am using Altera Cyclone IV X for hardware implementation, where Quartus fails to compile with error "Error (114016): Out of memory in module quartus_map.exe (8882 megabytes used) ". I think it is because of the high resource, please let me know if I am wrong.

Multipliers 518

Adders/Subtractors 27084

Registers 260726

Total 1-Bit Registers 3019571

RAMs 19

Multiplexers 119879

I/O Bits 46

Static Shift operators 9633

Dynamic Shift operators 3345

Looking forward to a reply.

Thank you

You can share resources by using the Sharing option (right click on a subsystem to see the option). The number of registers seem high, have you considered using the RAM block instead of registers?

Yes, I have checked RAM block option. The problem is that I am using single data type which implies 32bit register. Therefore the use of 1-bit register is significantly increased. Please see the report in the attachment.

Either I have to opt for fixed point conversion via Matlab tool or I have to do it manually. Via tool will take longer time as it will generate a suggestion for the whole project and I have search individual in order to adapt. Therefore now I am doing it manually.

Is there a possibility to set the size of a single data type other than 32 bit?

Other suggestions are welcome.

Thank you
