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.
