Development Tools
The ADSP-216x processors are supported by a complete set of
tools for system development. The ADSP-2100 Family Devel-
opment Software includes C and assembly language tools that
allow programmers to write code for any of the ADSP-216x
processors. The ANSI C compiler generates ADSP-216x assem-
bly source code, while the runtime C library provides ANSI-
standard and custom DSP library routines. The ADSP-216x
assembler produces object code modules that the linker com-
bines into an executable file. The processor simulators provide
an interactive instruction-level simulation with a reconfigurable,
windowed user interface. A PROM splitter utility generates
PROM programmer compatible files.
EZ-ICE
in-circuit emulators allow debugging of ADSP-21xx
systems by providing a full range of emulation functions such
as modification of memory and register values and execution
breakpoints. EZ-LAB
demonstration boards are complete DSP
systems that execute EPROM-based programs.
The EZ-Kit Lite is a very low-cost evaluation/development
platform that contains both the hardware and software needed
to evaluate the ADSP-21xx architecture.
Additional details and ordering information are available in the
ADSP-2100 Family Software & Hardware Development Tools
data
sheet (ADDS-21xx-TOOLS). This data sheet can be requested
from any Analog Devices sales office or distributor.
Additional Information
This data sheet provides a general overview of ADSP-216x
processor functionality. For detailed design information on the
architecture and instruction set, refer to the
ADSP-2100 Family
User’s Manual
, Third Edition, available from Analog Devices.
ARCHITECTURE OVERVIEW
Figure 1 shows a block diagram of the ADSP-216x architecture.
The processors contain three independent computational units:
the ALU, the multiplier/accumulator (MAC), and the shifter.
The computational units process 16-bit data directly and have
provisions to support multiprecision computations. The ALU
performs a standard set of arithmetic and logic operations;
division primitives are also supported. The MAC performs
single-cycle multiply, multiply/add, and multiply/subtract opera-
tions. The shifter performs logical and arithmetic shifts, normal-
ization, denormalization, and derive exponent operations. The
shifter can be used to efficiently implement numeric format control
including multiword floating-point representations.
The internal result (R) bus directly connects the computational
units so that the output of any unit may be used as the input of
any unit on the next cycle.
A powerful program sequencer and two dedicated data address
generators ensure efficient use of these computational units.
The sequencer supports conditional jumps, subroutine calls,
and returns in a single cycle. With internal loop counters and
loop stacks, the ADSP-216x executes looped code with zero
overhead—no explicit jump instructions are required to main-
tain the loop.
Two data address generators (DAGs) provide addresses for
simultaneous dual operand fetches (from data memory and
program memory). Each DAG maintains and updates four
address pointers. Whenever the pointer is used to access data
(indirect addressing), it is post-modified by the value of one of
four modify registers. A length value may be associated with
each pointer to implement automatic modulo addressing for
circular buffers. The circular buffering feature is also used by
the serial ports for automatic data transfers to (and from) on-
chip memory.
