 Half Precision Floating Point Unit from MERL
+
 This is the first ever Half Precision Floating Point Unit of IEEE-754 standard designed by undergraduate students of DHA Suffa University Pakistan. It support all the basic floating point instruction mention in RISC-V specs.

 Testing of Design
+
 Go to verilog/dv/FPU/ directory
 
 Set the GCC_PATH environment variable.
+
 Set the PDK_PATH environment variable.
+
 Copy the given program hex file into uart.hex.
+
 run the make commad for RTL simulation
+
 run the SIM=GL make command for netlist simulation
+
 Note: Dont forget to add 00000010 and 00000FFF instruction in the end of the uart.hex to stop the uart transmission if you are using your own codes.
