FIRGEN/MULTGEN - VHDL Core Generator

VHDL core generator

FIRGEN Project generates optimized VHDL codes for FIR Filters and Multiplier arrays
using "Nonrecursive Signed Common Subexpression Algorithm".

program writen on C++
--------------------------
firgen [OPTION..]
Available options are :
-w Input Data Width
-m Generate Only Multipliers Array
-a Generate Asynchronus Multipliers array (no CLK signal)
-e Use CLK_EN input
-c filter coefficients, coma separated
-o Output File Name
-? Help

Example For Use:
----------------
FirGen -w 16 -c 1,2,3,4,5 -o my_fir

this command generates 2 output files
my_fir.vhd - Main Fir module
my_fir_mult.vhd - Multipliers Array (DIn*C1, DIn*C2,..., DIn*Cn)

Input data width is 16 bit
Filter Coefitions : 1,2,3,4,5

Features

FIR Filter Generator
Multiplyer Array Generator with common input

Status

Stable and ready for use Ver1.1
Asynchronus operation
and CLK_En features added
