nios is slow when running with jtag

[taojinyong]

我写了一个闪烁LED的程序，该程序看起来应该闪烁250ms，但在我的FPGA上，它闪烁了大约2.5S，我的nios频率为80MHz。我不知道出了什么问题。我将UART配置为仅以19200的波特率运行，即使在更改了qsys或system.h文件之后也是如此！

if （TIME_SLICE >= 250000）

{

TIME_SLICE = 0;

IOWR_ALTERA_AVALON_PIO_DATA（LED_O_BASE，led_flag）;

led_flag = ~led_flag;

}

TIME_SLICE++;
