AT572D740
D740 is supported with a complete set of software and hardware development tools.
MADE
The D740 is supported by a set of development tools integrated into a visual develop-
ment environment called MADE (Multicore Application Development Environment).
MADE provides the user with an integrated environment for producing applications for
both the D740 cores, the ARM7TDMI and the mAgic DSP, by means of a common
project management and support for the MARMOS Minimal Bios.
Code generation tools for the ARM include the GNU Code Development Chain for
ARM7 (C-C++ compiler, assembler, linker and utilities) and the ARM SDT Code Devel-
opment Chain (C-C++ compiler, assembler, linker and utilities).
Code generation tools for mAgic include C compiler (GNU gcc based, ANSI compliant),
VLIW assembler-optimizer, code compressor, linker and utilities.
MADE supports the MARMOS Minimal Bios, a set of helper functions for the ARM-
mAgic intercommunication and the D740 peripherals management. MARMOS gives the
user the basic APIs for building an integrated ARM-mAgic application.
MADE provides the user with a simulation engine and an emulation kernel: the Cycle-
Accurate simulator and the D740 emulator board support.
JTAG-ICE
The ARM Standard In-Circuit-Emulation debug interface is supported via the JTAG-ICE
port of the D740.
When the ARM ICE configuration is selected, the usual debug capabilities for the ARM
System are supported, while the support for the mAgic core is limited to memory and
status registers inspection.
The 5 jtag pins are shared between ARM7TDMI ICE functionality and the DIOPSIS 740
chip Boundary Scan Logic. The “JCFG” pin acts as ARM jtag / D740 BSL selector.
When “JCFG” pin is high the ARM ICE is selected, while DIOPSIS 740 BSL is selected
when “JCFG” is low.
JTST
JTST is a low cost general-purpose module that provides the appropriate resources in order to
test DIOPSIS 740.
