FPADD Floating Point Pipelined Adder Unit IP Core

General Description:

The DFPADD IP Core uses the pipelined mathematics algorithm to compute sum of two argu-ments. The input numbers format is according to IEEE-754 standard. DFPADD supports single precision real number. Add operation was pipelined up to 5 levels. Input data are fed every clock cycle. The first result appears after 5 clock periods latency and next results are available each clock cycle. Full IEEE-754 precision and accuracy were included.
DFPADD is a technology independent design that can be implemented in a variety of process technologies.

Key Features:

Full IEEE-754 compliance
Single precision real format support
Simple interface
No programming required
5 levels pipeline

Overflow, underflow and invalid operation flags
Full accuracy and precision
Results available at every clock
Fully synthesizable
Static synchronous design
Positive edge clocking and no internal tri-states
Scan test ready

Applications:

Math coprocessors
DSP algorithms
Embedded arithmetic coprocessor
Fast data processing & control

Units

Argument checker

It performs input data analyze against IEEE-754 number standard compliance. The appropriate numbers and information about the input data classes are given as the results to Main FP Pipelined Unit.

Main FP Pipelined Unit

It performs floating point to integer conversion. Gives the complex information about the results to Result Composer module.

Result Composer

It performs floating point to integer conversion. Gives the complex information about the results to Result Composer module.
