生成的代码中，ACU_RAM和CFSM_RAM，分别代表什么含义？
CSA_RAM应该是控制表，DA_RAM是计算数据。

比如下面：
void Filter_Wave_Start()
{
/* Power on DFB */
Filter_Wave_PM_ACT_CFG |= Filter_Wave_PM_ACT_MSK;

if (Filter_Wave_isInitialized == 0)
{
      /* Turn off Run Bit */
      Filter_Wave_CR &= ~Filter_Wave_RUN_MASK;

      /* Power up the DFB RAMS */
      Filter_Wave_RAM_EN = Filter_Wave_RAM_DIR_BUS;

      /* Put DFB RAM on the bus */
      Filter_Wave_RAM_DIR = Filter_Wave_RAM_DIR_BUS;

      /* Write DFB RAMs */
      /* Control Store RAMs */
      cymemcpy( Filter_Wave_CSA_RAM,
         Filter_Wave_control, Filter_Wave_CSA_RAM_SIZE);
      cymemcpy(Filter_Wave_CSB_RAM,
         Filter_Wave_control, Filter_Wave_CSB_RAM_SIZE);
      /* CFSM RAM */
      cymemcpy(Filter_Wave_CFSM_RAM,
         Filter_Wave_cfsm, Filter_Wave_CFSM_RAM_SIZE);
      /* DAta RAMs */
      cymemcpy(Filter_Wave_DA_RAM,
         Filter_Wave_data_a, Filter_Wave_DA_RAM_SIZE);
      cymemcpy(Filter_Wave_DB_RAM,
         Filter_Wave_data_b, Filter_Wave_DB_RAM_SIZE);
      /* ACU RAM */
      cymemcpy(Filter_Wave_ACU_RAM,
         Filter_Wave_acu, Filter_Wave_ACU_RAM_SIZE);
      /* Take DFB RAM off the bus */
      Filter_Wave_RAM_DIR =Filter_Wave_RAM_DIR_DFB;
      /* Set up interrupt and DMA events */
      Filter_Wave_SetInterruptMode(Filter_Wave_INIT_INTERRUPT_MODE);
      Filter_Wave_SetDMAMode(Filter_Wave_INIT_DMA_MODE);

      /* Clear any pending interrupts */
      Filter_Wave_SR = 0xff;

      Filter_Wave_isInitialized = 1;
}
/* Turn on Run Bit */
Filter_Wave_CR |= Filter_Wave_RUN_MASK;
}
