signal processing, and are commonly used in digital filters and
Fourier transforms. The two DAGs of the ADSP-21365/6 con-
tain sufficient registers to allow the creation of up to 32 circular
buffers (16 primary register sets, 16 secondary). The DAGs
automatically handle address pointer wraparound, reduce over-
head, increase performance, and simplify implementation.
Circular buffers can start and end at any memory location.
Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations, for concise programming. For example, the
ADSP-21365/6 can conditionally execute a multiply, an add,
and a subtract in both processing elements while branching and
fetching up to four 32-bit values from memory—all in a single
instruction.
ADSP-21365/6 MEMORY AND I/O INTERFACE
FEATURES
The ADSP-21365/6 adds the following architectural features to
the SIMD SHARC family core.
On-Chip Memory
The ADSP-21365/6 contains three megabits of internal SRAM
and four megabits of internal mask-programmable ROM. Each
block can be configured for different combinations of code and
data storage (see
Table 2
). Each memory block supports single-
cycle, independent accesses by the core processor and I/O pro-
cessor. The ADSP-21365/6 memory architecture, in
combination with its separate on-chip buses, allow two data
transfers from the core and one from the I/O processor, in a sin-
gle cycle.
The ADSP-21365/6’s, SRAM can be configured as a maximum
of 96K words of 32-bit data, 192K words of 16-bit data, 64K
words of 48-bit instructions (or 40-bit data), or combinations of
different word sizes up to three 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 dou-
bles the amount of data that may be stored on-chip. Conversion
between the 32-bit floating-point and 16-bit floating-point for-
mats is performed 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.
