ADSP-21362/ADSP-21363/ADSP-21364/ADSP-21365/ADSP-21366
Harvard architecture, allow unconstrained data flow between
computation units and internal memory. The registers in PEX
are referred to as R0
–
R15 and in PEY as S0
–
S15.
Single-Cycle Fetch of Instruction and Four Operands
The ADSP-2136x features an enhanced Harvard architecture in
which the data memory (DM) bus transfers data and the pro-
gram memory (PM) bus transfers both instructions and data
(see
Figure 1 on Page 1
). With the processor’s separate program
and data memory buses and on-chip instruction cache, the pro-
cessor can simultaneously fetch four operands (two over each
data bus) and one instruction (from the cache), all in a
single cycle.
Instruction Cache
The ADSP-2136x includes an on-chip instruction cache that
enables three-bus operation for fetching an instruction and four
data values. The cache is selective—only the instructions whose
fetches conflict with PM bus data accesses are cached. This
cache allows full-speed execution of core, looped operations
such as digital filter multiply-accumulates, and FFT butterfly
processing.
Data Address Generators with Zero-Overhead Hardware
Circular Buffer Support
The ADSP-2136x’s two data address generators (DAGs) are
used for indirect addressing and implementing circular data
buffers in hardware. Circular buffers allow efficient program-
ming of delay lines and other data structures required in digital
signal processing, and are commonly used in digital filters and
Fourier transforms. The two DAGs contain 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 overhead, increase perfor-
mance, 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-2136x 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.
MEMORY AND I/O INTERFACE FEATURES
The ADSP-2136x adds the following architectural features to
the SIMD SHARC family core.
On-Chip Memory
The ADSP-2136x contains three megabits of internal SRAM
and four megabits of internal ROM. Each block can be config-
ured for different combinations of code and data storage (see
Table 3
). Each memory block supports single-cycle, indepen-
dent accesses by the core processor and I/O processor. The
processor’s memory architecture, in combination with its sepa-
rate on-chip buses, allows two data transfers from the core and
one from the I/O processor, in a single cycle.
