ROM Based Security
The processors have a ROM security feature that provides hard-
ware support for securing user software code by preventing
unauthorized reading from the internal code. When using this
feature, the processors do not boot-load any external code, exe-
cuting exclusively from internal ROM. Additionally, the
processor is not freely accessible via the JTAG port. Instead, a
unique 64-bit key, which must be scanned in through the JTAG
or Test Access Port, is assigned to each customer. The device
ignores an incorrect key. Emulation features are available after
the correct key is scanned.
Digital Transmission Content Protection
The DTCP specification defines a cryptographic protocol for
protecting audio entertainment content from illegal copying,
intercepting, and tampering as it traverses high performance
digital buses, such as the IEEE 1394 standard. Only legitimate
entertainment content delivered to a source device via another
approved copy protection system (such as the DVD content
scrambling system) is protected by this copy protection system.
For more information on this feature, contact your local ADI
sales office.
FAMILY PERIPHERAL ARCHITECTURE
The ADSP-2147x family contains a rich set of peripherals that
support a wide variety of applications including high quality
audio, medical imaging, communications, military, test equip-
ment, 3D graphics, speech recognition, motor control, imaging,
and other applications.
External Memory
The external memory interface supports access to the external
memory through core and DMA accesses. The external memory
address space is divided into four banks. Any bank can be pro-
grammed as either asynchronous or synchronous memory. The
external ports are comprised of the following modules.
