Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations, for concise programming. For example, the
ADSP-21363 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-21363 MEMORY AND I/O INTERFACE
FEATURES
The ADSP-21363 adds the following architectural features to
the SIMD SHARC family core.
On-Chip Memory
The ADSP-21363 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-21363 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 single cycle.
The ADSP-21363’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.
