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.
