ADSP-2109 Prototyping
You can prototype your ADSP-2109 system with the ADSP-
2104 RAM-based processor. When code is fully developed and
debugged, it can be submitted to Analog Devices for conversion
into a ADSP-2109 ROM product.
The ADSP-2101 EZ-ICE emulator can be used for develop-
ment of ADSP-2109 systems. For the 3.3 V ADSP-2109, a
voltage converter interface board provides 3.3 V emulation.
Additional overlay memory is used for emulation of ADSP-2109
systems. It should be noted that due to the use of off-chip
overlay memory to emulate the ADSP-2109, a performance loss
may be experienced when both executing instructions and
fetching program memory data from the off-chip overlay
memory in the same cycle. This can be overcome by locating
program memory data in on-chip memory.
Ordering Procedure for ADSP-2109 ROM Processor
To place an order for a custom ROM-coded ADSP-2109, you
must:
1. Complete the following forms contained in the ADSP ROM
2. Return the forms to Analog Devices along with two copies of
3. Place a purchase order with Analog Devices for nonrecurring
Ordering Package, available from your Analog Devices sales
representative:

the Memory Image File (.EXE file) of your ROM code. The

development.

After this information is received, it is entered into Analog
Devices’ ROM Manager System which assigns a custom ROM
model number to the product. This model number will be
branded on all prototype and production units manufactured to
these specifications.
To minimize the risk of code being altered during this process,
Analog Devices verifies that the .EXE files on both floppy disks
are identical, and recalculates the checksums for the .EXE file
entered into the ROM Manager System. The checksum data, in
the form of a ROM Memory Map, a hard copy of the .EXE file,
and a ROM Data Verification form are returned to you for
inspection.
A signed ROM Verification Form and a purchase order for
production units are required prior to any product being
manufactured. Prototype units may be applied toward the
minimum order quantity.
Upon completion of prototype manufacture, Analog Devices
will ship prototype units and a delivery schedule update for
production units. An invoice against your purchase order for the
NRE charges is issued at this time.
There is a charge for each ROM mask generated and a mini-
mum order quantity. Consult your sales representative for
details. A separate order must be placed for parts of a specific
package type, temperature range, and speed grade.
