ADSP-2181

REV. D
The 14-pin, 2-row pin strip header is keyed at the Pin 7 loca-
tion—you must remove Pin 7 from the header. The pins must
be 0.025 inch square and at least 0.20 inch in length. Pin spac-
ing should be 0.1 x 0.1 inches. The pin strip header must have
at least 0.15 inch clearance on all sides to accept the EZ-ICE
probe plug. Pin strip headers are available from vendors such as
3M, McKenzie and Samtec.
Target Memory Interface
For your target system to be compatible with the EZ-ICE emu-
lator, it must comply with the memory interface guidelines listed
below.
PM, DM, BM, IOM and CM
Design your Program Memory (PM), Data Memory (DM),
Byte Memory (BM), I/O Memory (IOM) and Composite
Memory (CM) external interfaces to comply with worst case
device timing requirements and switching characteristics as
specified in the DSP’s data sheet. The performance of the
EZ-ICE may approach published worst case specification for
some memory access timing requirements and switching
characteristics.
Note: If your target does not meet the worst case chip specifica-
tion for memory access parameters, you may not be able to
emulate your circuitry at the desired CLKIN frequency. De-
pending on the severity of the specification violation, you may
have trouble manufacturing your system as DSP components
statistically vary in switching characteristic and timing require-
ments within published limits.
Restriction: All memory strobe signals on the ADSP-2181
(
RD, WR, PMS, DMS, BMS, CMS and IOMS) used in your
target system must have 10 k
pull-up resistors connected when
the EZ-ICE is being used. The pull-up resistors are necessary
because there are no internal pull-ups to guarantee their state
during prolonged three-state conditions resulting from typical
EZ-ICE debugging sessions. These resistors may be removed at
your option when the EZ-ICE is not being used.
Target System Interface Signals
When the EZ-ICE board is installed, the performance on some
system signals changes. Design your system to be compatible
with the following system interface signal changes introduced by
the EZ-ICE board:
EZ-ICE emulation introduces an 8 ns propagation delay be-
tween your target circuitry and the DSP on the
RESET
signal.
EZ-ICE emulation introduces an 8 ns propagation delay be-
tween your target circuitry and the DSP on the
BR signal.
EZ-ICE emulation ignores
RESET and BR when single-
stepping.
EZ-ICE emulation ignores
RESET and BR when in Emulator
Space (DSP halted).
EZ-ICE emulation ignores the state of target
BR in certain
modes. As a result, the target system may take control of the
DSP’s external memory bus only if bus grant (
BG) is asserted
by the EZ-ICE board’s DSP.
Target Architecture File
The EZ-ICE software lets you load your program in its linked
(executable) form. The EZ-ICE PC program can not load sec-
tions of your executable located in boot pages (by the linker).
With the exception of boot page 0 (loaded into PM RAM), all
sections of your executable mapped into boot pages are not
loaded.
Write your target architecture file to indicate that only PM
RAM is available for program storage, when using the EZ-ICE
software’s loading feature. Data can be loaded to PM RAM or
DM RAM.
