MSC8122ADS
Description
• One instance of kernel code in all four SC140 cores.
• Dynamic and static memory allocation from local memory (M1) and shared memory (M2).
Enables transparent inter-task communications between tasks running inside the SC140 cores and the other tasks
running in on-board devices or remote network devices:
• Messaging mechanism between tasks using mailboxes and semaphores.
• Networking support; data transfer between tasks running inside and outside the device using networking
protocols.
• Includes integrated device drivers for such peripherals as TDM, UART, and external buses.
• Task debugging utilities integrated with compilers and vendors.
• Board support package (BSP) for the application development system (ADS).
• Integrated development environment (IDE):
— C/C++ compiler with in-line assembly so developers can generate highly optimized DSP code. Translates
C/C++ code into parallel fetch sets and maintains high code density.
— Librarian. User can create libraries for modularity.
— A collection of C/C++ functions for developer use.
— Highly efficient linker to produce executables from object code.
— Seamlessly integrated real-time, non-intrusive multi-mode debugger for debugging highly optimized DSP
algorithms. The developer can choose to debug in source code, assembly code, or mixed mode.
— Device simulation models enable design and simulation before hardware availability.
— Profiler using a patented binary code instrumentation (BCI) technique helps developers identify program
design inefficiencies.
— Version control. Metrowerks® CodeWarrior® includes plug-ins for ClearCase, Visual SourceSafe, and
CVS.
• External memory.
• External host.
• UART.
• TDM.
• I2C
• Host debug through single JTAG connector supports both processors.
• MSC8103 as the MSC8122 host with both devices on the board. The MSC8103 system bus connects to the
MSC8122 DSI.
• Flash memory for stand-alone applications.
• Communications ports:
— 10/100Base-T.
— 155 Mbit ATM over Optical.
— T1/E1 TDM interface.
— H.110.
— Voice codec.
— RS-232.
— High-density (MICTOR) logic analyzer connectors to monitor MSC8122 signals
— 6U CompactPCI form factor.
• Emulates MSC8122 DSP farm by connecting to three other ADS boards.
