empty:FIFO空的标记信号,为高电平时表示FIFO已空,不能在进行读操作。 usedw[](number of words in theFIFO):显示存储在FIFO中数据个数的信号,Note:(可以使用最高位作为FIFO的半满指示信号。) almost full:接近满信号,当usedw信号的值大于或等于我们设置的almost full的值时,该信号置为高电平,是full信号的提前...
可以将FIFO的Empty和Almost_empty以及读使能配合起来使用,来保证能够连续读,并准确的判断FIFO空满状态,提前决定是否能启动读使能。具体的实施办法是:当Empty为1,立即停止读;当Empty为0,Almost_empty为0时,可以放心读;当Empty为0,但是Almost_empty为1时,如果上一拍读使能Read也为1,那么不能读;当Empty为0,但是Almo...

FIFO memory system and method with improved generation of empty and full control signals in one clock cycle using almost empty and almost full signalsUS6389490 * May 9, 2000 May 14, 2002 Xilinx, Inc. FIFO memory system and method with improved generation of empty and full control signals in...
The ALMOST_EMPTY control signal is latched by the first register at the next rising edge of a read clock signal, thereby causing the register to generate a high EMPTY control signal in the same read clock cycle during which the last data value is read from the FIFO memory. Similarly, an ...
The state machine manipulates the inputs to produce an output signal representing an Almost Empty output flag that is at a first logic state when a FIFO is Almost Empty and is at a second logic state when the FIFO is Not Almost Empty....
