signal processing, and are commonly used in digital filters and
Fourier transforms. The two DAGs of the ADSP-21364 contain
sufficient registers to allow the creation of up to 32 circular buff-
ers (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-21364 can conditionally execute a multiply, an add, and a
subtract in both processing elements while branching and fetch-
ing up to four 32-bit values from memory—all in a single
instruction.
ADSP-21364 MEMORY AND I/O INTERFACE
FEATURES
The ADSP-21364 adds the following architectural features to
the SIMD SHARC family core.
On-Chip Memory
The ADSP-21364 contains three megabits of internal SRAM.
Each block can be configured for different combinations of code
and data storage (see
Table 2 on Page 5
). Each memory block
supports single-cycle, independent accesses by the core proces-
sor and I/O processor. The ADSP-21364 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-21364’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 differ-
ent 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 float-
ing-point storage format is supported that effectively doubles
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.
