Spartan-7: Advantage of SelectMAP over SlaveSerial

Jump to solution

Hello,

what are the advantages of using SelectMAP over SlaveSerial?

  • SelectMAP uses more wires than SlaveSerial. But these wires can be re-used after configuration.
  • SelectMAP can use 8, 16 or 32 Bit
  • SelectMAP is faster than SlaveSerial, because of more wires.
  • Readback of the FPGA Configuration is only possible with SelectMAP
  • Partial Configuration is possible with SelectMAP and SlaveSerial

Are my assumptions correct?

  • SelectMAP uses more wires than SlaveSerial. But these wires can be re-used after configuration.
    • > Yes, multi-purpose pins can be used after configuration. Kindly check Table 2-4: Configuration Pin Definitions in UG470 (v1.13.1)
  • SelectMAP can use 8, 16 or 32 Bit
  • SelectMAP is faster than SlaveSerial, because of more wires.
    • > Yes
  • Readback of the FPGA Configuration is only possible with SelectMAP
    • Yes in comparison with Slave serial
  • Partial Configuration is possible with SelectMAP and SlaveSerial
