void macUSART_INT_FUN(void)
{
OS_ERR err;
char * p_mem_blk;

OSIntEnter();
p_mem_blk = OSMemGet((OS_MEM    *)&mem,    (OS_ERR    *)&err);
if ( USART_GetITStatus ( macUSARTx, USART_IT_RXNE ) != RESET )
{
  * p_mem_blk = USART_ReceiveData ( macUSARTx );

  OSTaskQPost ((OS_TCB    *)&AppTaskTestTCB,
      (void       *)p_mem_blk,
      (OS_MSG_SIZE  )1,
      (OS_OPT    )OS_OPT_POST_FIFO,
      (OS_ERR    *)&err);

}
  OSIntExit();
}

这是我的串口接收程序  ，每次接收一个直接就发信号出去。我该如何处理收到一帧数据在发出去呢。我的裸机程序如下：
void USART1_IRQHandler(void)
{
if(USART_GetITStatus(USART1, USART_IT_RXNE) != RESET)
{
  USART1RxBuff[USART1RxBuffTrail]=(u8)(USART_ReceiveData(USART1));
  USART1RxBuffTrail++;
  USART1RxBuffTrail=USART1RxBuffTrail%MAX_BUSCOM_RX_BUFF;
}
}

void USART1_CheckRx(void)
{
u8 DataTemp;
if(USART1RxBuffHead^USART1RxBuffTrail)
{
  DataTemp=USART1RxBuff[USART1RxBuffHead];
  if (USART1FrameRxIndex == 0)
  {
   if (DataTemp == USART1_FRAME_HEAD)
{
USART1FrameRxBuff[USART1FrameRxIndex]=DataTemp;
USART1FrameRxIndex++;
}
  }
  else if(USART1FrameRxIndex == 1)
  {
if(DataTemp<=MAX_BUSCOM_FRAME_RX_LEN)
{
USART1FrameRxBuff[USART1FrameRxIndex]=DataTemp;
USART1FrameRxIndex++;
}
else
{
USART1FrameRxIndex=0;
}
  }
  else
  {
if(USART1FrameRxIndex == (USART1FrameRxBuff[1]+1))
{
if(DataTemp==BusCom_GetCrc(&USART1FrameRxBuff[0],USART1FrameRxBuff[1]+1))
{
   USART1CountKey = USART1FrameRxBuff[2];
      USART_KEY_CTRL();
}
USART1FrameRxIndex=0;
}
else
{
USART1FrameRxBuff[USART1FrameRxIndex]=DataTemp;
USART1FrameRxIndex++;
}
  }
  USART1RxBuffHead++;
  USART1RxBuffHead=USART1RxBuffHead%MAX_BUSCOM_RX_BUFF;
}
}
  现在问题来了，要是在UCOS 中断里面处理这段程序的话，时间太长，肯定不行，如果每次都调用的话我又觉得不是是个很好的方案，请问下有那位可以帮我向各解决方案吗~！我对UCOS 不是很熟悉，谢谢
