Connecting CLK IN to Pin 4 of the EZ-ICE
header is optional.
T he emulator only uses CLK IN when directed to perform
operations such as starting, stopping and single-stepping mul-
tiple ADSP-21061 in a
synchronous
manner. If you do not need
these operations to occur synchronously on the multiple proces-
sors, simply tie Pin 4 of the EZ-ICE
header to ground.
If synchronous multiprocessor operations are needed and
CLK IN is connected, clock skew between the multiple ADSP-
21061/ADSP-21061L processors and the CLK IN pin on the
EZ-ICE
header
must be minimal
. If the skew is too large, syn-
chronous operations may be off by one or more cycles between
processors. For synchronous multiprocessor operation T CK ,
T MS, CLK IN and
EMU
should be treated as critical signals in
terms of skew, and should be laid out as short as possible on
your board. If T CK , T MS and CLK IN are driving a large num-
ber of ADSP-21061 (more than eight) in your system, then
treat them as a clock tree using multiple drivers to minimize
skew. (See Figure 7, JT AG Clock T ree, and Clock Distribution
in the High Frequency Design Considerations section of the
ADSP-2106x User’s Manual, Second Edition
.)
If synchronous multiprocessor operations are not needed (i.e.,
CLK IN is not connected), just use appropriate parallel termina-
tion on T CK and T MS. T DI, T DO,
EMU
and
TRST
are not
critical signals in terms of skew.
