Code Submission
B.2 Code Submission
ROM codes for 28x devices (in COFF format) may be submitted as an attach-
ment to email or in a 3
½
inch floppy. Each ROM code submitted is assigned
a unique “D-number” in the format DExxxnnn. When code is submitted to TI
for masking, the code is reformatted to accommodate the TI mask-generation
system. System-level verification by the customer is, therefore, necessary to
ensure the reformatting remains transparent and does not affect the execution
of the algorithm. The formatting changes involve the removal of address-re-
location information (the code address begins at the base address of the ROM
in the TMS320 device and progresses without gaps to the last address of the
ROM) and the addition of data in the reserved locations of the ROM for device
ROM test. Because these changes have been made, a checksum comparison
is not a valid means of verification.
With each masked-device order, the customer must sign a disclaimer that
states:
The units to be shipped against this order were assembled, for expe-
diency purposes, on a prototype (that is, non-production qualified)
manufacturing line, the reliability of which is not fully characterized.
Therefore, the anticipated inherent reliability of these prototype units
cannot be expressly defined.
Customers must also sign a release that states:
Any masked ROM device may be resymbolized as TI standard prod-
uct and resold as though it were an unprogrammed version of the de-
vice, at the convenience of Texas Instruments.
