external code, executing exclusively from internal ROM. Addi-
tionally, 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 will be assigned to each customer.
The device will ignore a wrong key. Emulation features and
external boot modes are only available after the correct key is
scanned.
FAMILY PERIPHERAL ARCHITECTURE
The ADSP-21371/ADSP-21375 family contains a rich set of
peripherals that support a wide variety of applications, includ-
ing high quality audio, medical imaging, communications,
military, test equipment, 3D graphics, speech recognition, mon-
itor control, imaging, and other applications.
External Port
The external port on the ADSP-21371/ADSP-21375 SHARC
processors provide a high performance, glueless interface to a
wide variety of industry-standard memory devices. The 32-bit
wide bus (ADSP-21371) may be used to interface to synchro-
nous and/or asynchronous memory devices through the use of
its separate internal memory controllers: the first is an SDRAM
controller for connection of industry-standard synchronous
DRAM devices and DIMMs (dual inline memory module),
while the second is an asynchronous memory controller
intended to interface to a variety of memory devices. Four
memory select pins enable up to four separate devices to coexist,
supporting any desired combination of synchronous and asyn-
chronous device types.
