Port number limitation prevents my codes from compiling

I have two questions. What I want to do is : I want to send 144 8bit numbers from my computer to FPGA, and let the FPGA store the numbers in memory in the FPGA. And let the verilog bloc...

How are you expecting the CPU to send these numbers? Your current code expects each number to have it's own individual input. Even if you did find an FPGA to accomodate this, how would you connect these to a CPU?

You need to think about the interface you intend to use between the CPU and FPGA and re-code accordingly. Maybe a single RS232 interface? or SPI? Ethernet? PCIe?

I suggest something simple.

Writing numbers to FPGA memory is a pretty simple task, but you wouldnt transfer the numbers directly to the FPGA pins.
