Development System
T he ADSP-2100 Family Development Software, a complete set
of toolsfor softwareand hardwaresystem development, supports
the ADSP-217x. T he System Builder provides a high-level
method for defining the architecture of systems under develop-
ment. T heAssembler hasan algebraic syntax that iseasy to
program and debug. T he Linker combines object files into
an executable file. T he Simulator provides an interactive
instruction-level simulation with a reconfigurable user interface
to display different portions of the hardware environment. A
PROM Splitter generates PROM programmer compatible files.
T he C Compiler, based on the Free Software Foundation’s
GNU C Compiler, generates ADSP-217x assembly source
code. T he Runtime Library includes over 100 ANSI-standard
mathematical and DSP-specific functions.
EZ-T ools, low cost, easy-to-use hardware tools, also support the
ADSP-217x.
T he ADSP-217x EZ-ICE
Emulator aids in the hardware de-
bugging of ADSP-217x systems. T he emulator consists of hard-
ware, host computer resident software, the emulator probe, and
the pin adaptor. T he emulator performs a full range of emula-
tion functions including stand-alone operation or operation in
the target, setting up to 20 breakpoints, single-step or full-speed
operation in the target, examining and altering registers and
memory values, and PC upload/download functions. If you plan
to use the emulator, you should consider the emulator’s restric-
tions (differences between emulator and processor operation).
T he EZ-LAB
Evaluation Board is a PC plug-in card, but it can
operate in stand-alone mode. T he evaluation board/system de-
velopment board executes EPROM-based or downloaded pro-
grams. Modular Analog Front End daughter cards with different
codecs will be made available.

Additional Information
T his data sheet provides a general overview of ADSP-217x
functionality. For additional information on the architecture and
instruction set of the processor, refer to the
ADSP-2100 Family
User’s Manual
. For more information about the Development
System and ADSP-217x programmer’s reference information,

Figure 1 is an overall block diagram of the ADSP-217x. T he
processor contains three independent computational units: the
ALU, the multiplier/accumulator (MAC) and the shifter. T he
computational units process 16-bit data directly and have provi-
sions to support multiprecision computations. T he ALU per-
forms a standard set of arithmetic and logic operations; division
primitives are also supported. T he MAC performs single-cycle
multiply, multiply/add and multiply/subtract operations with
40 bits of accumulation. T he shifter performs logical and
arithmetic shifts, normalization, denormalization, and derive
exponent operations. T he shifter can be used to efficiently
implement numeric format control including multiword and
block floating-point representations.
T he internal result (R) bus directly connects the computational
units so that the output of any unit may be the input of any unit
on the next cycle.
A powerful program sequencer and two dedicated data address
generators ensure efficient delivery of operands to these compu-
tational units. T he sequencer supports conditional jumps, sub-
routine calls and returns in a single cycle. With internal loop
counters and loop stacks, the ADSP-217x executes looped code
with zero overhead; no explicit jump instructions are required to
maintain the loop.
