说明： 利用FPGA实现浮点运算的verilog代码
希望能够给需要做这方面研究的同仁有所帮助
(use FPGA floating-point operations verilog code hope to be able to do this to the need for research in the Tongren help)

FPU Notes
---------
1) The FPU will never generate a SNAN output
1a) The SNAN output is asserted when one of the operands
was a signaling NAN (output will be a quiet NAN).
1b) The QNAN output is asserted whenever the OUTPUT of
the FPU is NAN (always a quiet NAN).
FPU
===
The FPU consists of the following files:
verilog/fpu.v
verilog/pre_norm.v
verilog/primitives.v
verilog/post_norm.v
verilog/except.v",
verilog/pre_norm_fmul.v
(fpu.v is the top level)
The testbench is in: test_bench/test_top.v
To simulate the FPU using the included test bench
use a comand like:
verilog test_bench/test_top.v \
verilog/fpu.v \
verilog/pre_norm.v \
verilog/primitives.v \
verilog/post_norm.v \
verilog/except.v \
verilog/pre_norm_fmul.v
FCMP
====
The FP compare consists of
fcmp/verilog/fcmp.v
The testbench for FP compare is in: fcmp/test_bench/test_top.v
To simulate the FP compare using the included test bench
use a comand like:
verilog fcmp/test_bench/test_top.v \
fcmp/verilog/fcmp.v
MISC
====
Do not change the directory structure, the testbench
depends on it !
Please also read the README file in the test_vectors
directory.
