processor. The memory architecture, in combination with its
separate on-chip buses, allows two data transfers from the core
and one from the I/O processor, in a single cycle.
The SRAM can be configured as a maximum of 64k words of
32-bit data, 128k words of 16-bit data, 42k words of 48-bit
instructions (or 40-bit data), or combinations of different word
sizes up to two megabits. All of the memory can be accessed as
16-bit, 32-bit, 48-bit, or 64-bit words. A 16-bit floating-point
storage format is supported that effectively doubles the amount
of data that can be stored on-chip. Conversion between the
32-bit floating-point and 16-bit floating-point formats is per-
formed in a single instruction. While each memory block can
store combinations of code and data, accesses are most efficient
when one block stores data using the DM bus for transfers, and
the other block stores instructions and data using the PM bus
for transfers.
Using the DM bus and PM buses, with one bus dedicated to
each memory block, assures single-cycle execution with two
data transfers. In this case, the instruction must be available in
the cache.
On-Chip Memory Bandwidth
The internal memory architecture allows programs to have four
accesses at the same time to any of the four blocks (assuming
there are no block conflicts). The total bandwidth is realized
using the DMD and PMD buses (2x64-bits, core CLK) and the
IOD0/1 buses (2x32-bit, PCLK).
ROM-Based Security
The ADSP-21367/ADSP-21368/ADSP-21369 have a ROM secu-
rity feature that provides hardware support for securing user
software code by preventing unauthorized reading from the
internal code when enabled. When using this feature, the pro-
cessor does not boot-load any external code, executing
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 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.
