A0
This resultingword allows to identifythe appropri-
ate memory [cs2-cs0] and its respective address
[add6-add0] where the relative I0-I7 are to be
stored.
When the CHM pin is
high
, during the off-line
phase, W.A.R.P. generates the addresses for its
internalmemoriesandsendthoseaddressestothe
single external memory support where data (.dat
file) are located.These addresses, which are sent
by means of the EPA0-EPA2 and A0-A9 (EPA0
MSB, A9 LSB) output pins, allow to identify the
data (on the EPROM) that have be loaded
W.A.R.P. internal memories.
In on-linemode A0-A9 are not used.
I0-I7:
During the off-line phase these 8 data input
pins accept the microcode configurationand data
to be written into the internalmemories. The ante-
cedent memory word size is 64 bits, soit is neces-
sary to giveeachword 8 bitsat atime. In the same
way are written the words ofconsequentmemory
and of program memory.
In on-linemode this bus carries the inputvariables
to W.A.R.P.. Input values havea resolutionof6 or
7 bits inaccordancewith the configurationsetting.
PRST:
This is the restart pin of W.A.R.P.. It is
possibleto restart thework during the computation
(on-line phase) or before the writing of internal
memories (off-linephase).In bothcasesit mustbe
put
low
at least fora clock period.
FIN:
During the on-line phase it will start the run-
time acquisition cycle. This pin is activated by
providinga positive pulse fora time no lower than
an entire clock period. When all expected inputs
have been processed, a new FIN pulse must be
sent to activate anew process.
OFL:
When this pin is
high
, the chip is enabled to
load data in the internal RAMs (off-line phase). It
must be
low
whenthefuzzycontrolleris waitingfor
input valuesand during the processingphase(on-
line phase).
CHM:
Thispin,whichisusedonlyduringtheoff-line
phase, determines the charge mode. CHM is not
present in W.A.R.P. 1.0 release.
When CHM is
low
the addresses of the internal
memory locations where data have to be stored
in
must be sent to W.A.R.P. from the outside by
means of the input pins A0-A9.
When CHM is
high
W.A.R.P. automaticallygener-
ates the addresses of its internal memories and
manages the EPROMs reading by means of the
addresses contained in EPA0-EPA2 and A0-A9
output pins(13 bits).
TE
: Fortesting purpose only. It must be connected
to V
SS
.
MTE:
For testing purpose only. It must be con-
nected to V
SS
.
MCLK:
This is the input master clock whose fre-
quencycan reach up to 40MHz(MAX).
During the off-line phase with CHM
high
, the
DCLKsignal with a frequencyof MCLK/32 is gen-
erated in order to drive the downloading phase
timing.
EPA0-EPA2
: Duringthe off-linephase and in cor-
respondencewith CHM
high
, theseoutputpins are
joined (as MSB) to A0-A9 to obtainethe complete
address of the memory supportwhere to read the
data to be loadedin W.A.R.P.internal memories.
EPA0-EPA2 are not used when CHM is
low
or in
W.A.R.P. 1.0 release.
O0-O9
: These pins carry out the output values.
When the STB (strobe pin) is
high
, one output
variablecan beread byexternaldevices(inon-line
mode). The resolution of output variables is 1024
points(10 bits). Ifthere are more than oneoutput,
the outputvariables are calculatedoneby oneand
theyare providedinthe sequencestabilized during
the editing phase (see W.A.R.P.-SDT User Man-
ual).
OCNT0-OCNT3:
This4bit outputbusprovides the
output variables with a progressive number during
the on-line phase. As a consequenceit is possible
to know to which variable correspond thedata that
areonthe outputdatabus(O0-O9).Thedimension
of OCNT bus is connected with the maximum
number ofoutput variables (16).
STB:
The strobepinenablesthe user to utilize the
output.When thispin is
high
itindicatesthat a new
output variable has been calculated and it is ready
on the output bus (O0-O9). This signal synchro-
nizes the external devices and in particular the
interfaces with the controlled processes (on-line
mode).
EP:
This signal
low
indicates that the processing
of all the rules has been completed.
NP:
This output pin indicates that a new process
can start. NP is automatically set
low
before the
lastoutputhasbeencalculated,sothatitispossible
to start a new data acquisitionbefore (with a new
FIN) the computationis terminated.
