If you need to check status often, you will need to flush JTAG often, that will slowdown the speed if you are using a USB JTAG cable. The method I use for Blackfin target I'm working on now is to add some waiting cycles instead of checking the status. The key is to find the minimal number of the required cycles. You will need experiments to find it out. I also used that method for UrJTAG/gdbproxy Blackfin target. It works very well.
