This includes five CAN 2.0B ports with up to 2.5Mb/s data rate, four 10/100 Ethernet ports, an integrated Gigabit Ethernet port, a multi-media card interface and support for external QSPI and NOR x16 memory. The TMS320DM642AZNZ6 also includes an integrated external Memory Controllers (EMC) offering fast data access and external memory access. Furthermore, the device provides an intuitive debug environment and advanced debugging features, enabling developers to quickly identify bugs and reduce development time.

Working Principle

The TMS320DM642AZNZ6 is designed to efficiently process data, execute algorithms and support the latest multimedia-applications. A main feature of the TMS320DM642AZNZ6 is its multicore architecture, comprised of two Power Processor Units (PPUs). The device also operates on an advanced DSP architecture based on a VLIW (Very Long Instruction Word) instruction set. VLIW allows for the parallel execution of up to two operations in each instruction; and by combining multiple instructions, the device is able to execute up to four operations in parallel.

The TMS320DM642AZNZ6 uses multiple-source instruction generation (MSIG) to optimize application execution time. Essentially, the MSIG technique can generate instructions to take advantage of the processor’s VLIW capabilities. Additionally, the TMS320DM642AZNZ6 has a high-level program memory architecture so that it can utilize the Level-one and Level-two caches to facilitate program execution.

The TMS320DM642AZNZ6 also includes a Multi-Tasking Kernel (MTK) that allows multiple tasks to be running on the device simultaneously. The MTK enables the device to switch between tasks quickly, significantly decreasing system latency. Furthermore, the device also supports trace-based debugging, enabling developers to identify and debug errors, quickly minimizing development and debugging cycle times.

The TMS320DM642AZNZ6 is also designed to significantly reduce the development cycle time of new products through its on-chip debugging capabilities. This feature enables developers to quickly build, test and debug their application. The TMS320DM642AZNZ6 also offers software development tools for building cross-platform applications. This enables developers to create applications for Windows and Linux operating systems, as well as RTOSes, without having to rewrite code.

Conclusion

The TMS320DM642AZNZ6 provides a cost-effective and reliable solution for applications ranging from voice and video encoding to image processing and embedded system control. With its high performance and scalability, the device is suitable for applications that require low latency, high quality and low power consumption. Additionally, the TMS320DM642AZNZ6 provides advanced debugging features and software development tools that make the programming and development process easier. The TMS320DM642AZNZ6 is an ideal choice for developers of high-end embedded systems.
