GENERAL DESCRIPTION
The ADSP-21065L is a powerful member of the SHARC
family of 32-bit processors optimized for cost sensitive appli-
cations. The SHARC—Super Harvard Architecture—offers the
highest levels of performance and memory integration of any
32-bit DSP in the industry—they are also the only DSP in the
industry that offer both fixed and floating-point capabilities,
without compromising precision or performance.
The ADSP-21065L is fabricated in a high speed, low power
CMOS process, 0.35 mm technology. With its on-chip instruc-
tion cache, the processor can execute every instruction in a
single cycle. Table I lists the performance benchmarks for the
ADSP-21065L.
The ADSP-21065L SHARC combines a floating-point DSP
core with integrated, on-chip system features, including a
544 Kbit SRAM memory, host processor interface, DMA con-
troller, SDRAM controller, and enhanced serial ports.

ADSP-21000 FAMILY CORE ARCHITECTURE
The ADSP-21065L is code and function compatible with the
ADSP-21060/ADSP-21061/ADSP-21062. The ADSP-21065L
includes the following architectural features of the SHARC
family core.

Independent, Parallel Computation Units
The arithmetic/logic unit (ALU), multiplier, and shifter all
perform single-cycle instructions. The three units are arranged
in parallel, maximizing computational throughput. Single multi-
function instructions execute parallel ALU and multiplier
operations. These computation units support IEEE 32-bit
single-precision floating-point, extended precision 40-bit floating-
point, and 32-bit fixed-point data formats.
Data Register File
A general-purpose data register file is used for transferring data
between the computation units and the data buses, and for
storing intermediate results. This 10-port, 32-register (16 primary,
16 secondary) register file, combined with the ADSP-21000
Harvard architecture, allows unconstrained data flow between
computation units and internal memory.
Single-Cycle Fetch of Instruction and Two Operands
The ADSP-21065L features an enhanced Super Harvard Archi-
tecture in which the data memory (DM) bus transfers data and
the program memory (PM) bus transfers both instructions and
data (see Figure 1). With its separate program and data memory
buses, and on-chip instruction cache, the processor can simulta-
neously fetch two operands and an instruction (from the cache),
all in a single cycle.
Instruction Cache
The ADSP-21065L includes an on-chip instruction cache that
enables three-bus operation for fetching an instruction and two
data values. The cache is selective—only the instructions that
fetches conflict with PM bus data accesses are cached. This
allows full-speed execution of core, looped operations such as
digital filter multiply-accumulates and FFT butterfly processing.
Data Address Generators with Hardware Circular Buffers
The ADSP-21065L’s two data address generators (DAGs)
implement circular data buffers in hardware. Circular buffers
allow efficient programming of delay lines and other data
