○ FXAM
– examine input data
○ FUCOM
– comparison
○ FSIN, FCOS – sine, cosine
○ FTAN
– tangent
○ FATAN
– arctangent
○ FILDW, FILD – 16-bit, 32-bit integer to float
○ FISTW, FIST – float to 16-bit, 32-bit integer
● Exceptions built-in routines
● Masks each exception indicator:
○ Precision lack PE
○ Underflow result UE
○ Overflow result OE
○ Invalid operand IE
○ Division by zero ZE
○ Denormal operand DE
● Fully configurable
● Fully synthesizable, static synchronous
design with no internal tri-states

LICENSING
Comprehensible and clearly defined licensing
methods without royalty fees make using of
IP Core easy and simply.
Single Design license allows using IP Core in
single FPGA bitstream and ASIC implemen-
tation. It also permits FPGA prototyping be-
fore ASIC production.
Unlimited Designs license allows using IP
Core in unlimited number of FPGA bitstreams
and ASIC implementations.
In all cases number of IP Core instantiations
within a design, and number of manufactured
chips are unlimited. There is no time of use
limitations.
● Single Design license for
○ VHDL, Verilog source code called HDL
Source
○ Encrypted, or plain text EDIF called Netlist
● Unlimited Designs license for
○ HDL Source
○ Netlist
● Upgrade from
○ Netlist to HDL Source
○ Single Design to Unlimited Designs
