说明: 这是一个基于xilinx ISE9.1的一个历程,包含两个FIFO代码,第一个FIFO读写用同一个时钟,第二个FIFO读写用不同的时钟。
(This is based on the xilinx ISE9.1 a course, contains the code of the two FIFO, the first FIFO read and write with a clock, a second FIFO read and write with a different clock.)

DESCRIPTION: FIFO controller
For a full functional description see Application Note 258:
http://www.xilinx.com/xapp/xapp258.pdf
Design Type: ISE (chip 2V40 FG256 -4)
Source Files:
fifoctlr_cc - FIFO controller top level. Implements a 511x8 FIFO with common
read/write clocks.
fifoctlr_ic - FIFO controller top level. Implements a 511x8 FIFO with independent
read/write clocks.
Inputs:
* read_clock_in
* write_clock_in
* read_enable_in
* write_enable_in
* fifo_gsr_in
* write_data_in[7;0]
Outputs:
* read_data_out[7:0]
* full_out
* empty_out
* fifostatus_out[3:0]
SIMULATION:
Requires the following simulation libraries:
Unisims
Simprims
Behavioural and RTL Simulation done using VHDL Testbench
(fifoctlr_cc_tb.vhd and fifoctlr_ic_tb.vhd)
NOTE: If you are trying to run this example in a read-only location,
the design hierachy will not display properly. Please copy the example
project to a new location by using either Project Save As... from the File menu
pulldown in ISE or some other method of your choice. Copy the example to a location
where you have write permissions and the hiearchy will display properly.
