.SH NAME
DPGEN_FIFO \- FIFO Macro-Generator
.SH SYNOPSIS
.sp
\fB#include  <genlib.h>
.sp
void GENLIB_MACRO (DPGEN_FIFO, char *\fImodelname\fB, long \fIflags\fB, long \fIN\fB);
\fR
.SH "DESCRIPTION"
.PP
Generate a FIFO of \fIregNumber\fR words of \fIN\fR bits named \fImodelname\fR\&.
.PP
How it works :
.TP 0.2i
\(bu
datain0 and datain1 : the two write busses. Only one
is used to actually write the FIFO, it is selected by
the sel signal.
.TP 0.2i
\(bu
sel : when set to \&'0' the datain0 is used to write
the register word, otherwise it will be datain1\&.
.TP 0.2i
\(bu
r, rok : set r when a word is requested, rok tells
that a word has effectively been popped (rok == not empty).
.TP 0.2i
\(bu
w, wok : set w when a word is pushed, wok tells
that the word has effectively been pushed (wok == not full).
.SS "TERMINAL NAMES"
.TP 3
1. 
ck : clock signal (input, 1 bit). 
.TP 3
2. 
reset : reset signal (input, 1 bit). 
.TP 3
3. 
r : read requested (input, 1 bits). 
.TP 3
4. 
w : write requested (input, 1 bits). 
.TP 3
5. 
rok : read acknowledge (output, 1 bits). 
.TP 3
6. 
wok : write acknowledge (output, 1 bits). 
.TP 3
7. 
sel : select the write bus (input, 1 bit). 
.TP 3
8. 
datain0 :  first write bus (input, \fIN\fR bits). 
.TP 3
9. 
datain1 :  second write bus (input, \fIN\fR bits). 
.TP 3
10. 
dataout : read bus (output, \fIN\fR bits). 
.TP 3
11. 
vdd : power. 
.TP 3
12. 
vss : ground.
