Hello Sir, I am working on a system which require 8 serial ports. Most of the FPGA boards have at the maximum of two serial ports. Can I implement other serial ports on the FPGA using the IO pins. How many serial ports can be implemented? What additional circuitry will I require to interface it with other systems. Reagrds Leiser

Obviously your "serial port" is a RS232 port and in a FPGA it is an ordinary IO pin ... > How many serial ports can be implemented? That depends on the size and the pincount of your FPGA. But you wlii be able to pack at least fifty to hundred RX/TX ports even in the smallest FPGA nowadays. > What additional circuitry will I > require to interface it with other systems. If your "serial port" is a RS232 port, then you will need a driver/level shifter like the MAX232...
Yes, it is possible to wirte an Uart in a hardware description language and put it 8 time in a design. The question is, how is your dataflow? After, you will have 8 latches with the received values. What is doing with this registers? Do you what to calculate something or send this the anohter IN/Output port?
Hello, I have 8 differrent sensors and actuators which need to be controlled over RS232/485/422. The data from sensors need to be read and passed to either a softcore processor or a seprate processor for algorithms to work. The output from the processor needs to directed to actuators. How can this be implemented. Can I do some basic sorting and pre processing of data on FPGA and then transmit it forward? Regards Leiserhartbeck

But you have to know FPGA development need more time as software develoment. If you want to try different algorithm, this is simplier to solve in software.
Hello, My major algorithms run on software and on main processor. Is there a place where I can get schematic diagrms of boards utilising FPGA with processor which I can use for designing my own board? Regards Leiserhartbeck
