DSPLIB： The DSPLIB bundle is an optimized DSP Function Library package together with the software tools (SWTOOLS) package in bundle format to simplify the release procedure. MCSDK： The BIOS Multicore Software Development Kit (MCSDK) provides
the core foundational building blocks that facilitate application
software development on TI's high performance and multicore DSPs.
The foundational components include:
• SYS/BIOS which is a light-weight real-time embedded
operating system for TI devices
• Chip support libraries, drivers, and basic platform utilities
• Run-time libraries
• Interprocessor communication for communication across
cores and devices
• Basic networking stack and protocols
• Optimized application-specific and application non-specific algorithm libraries
• Debug and instrumentation
• Bootloaders and boot utilities
• Demonstrations and examples
NDK：The Network Developer's Kit (NDK) is a platform for development and demonstration of network enabled applications on TI embedded processors, currently limited to the TMS320C6000 family and ARM processors. The code included in this NDK release is generic C code which runs on any C64P, C66, C674, ARM9, Cortex-A8 or Cortex-M3 device (for C6000 processors, both big endian and little endian modes are supported). Users can obtain an appropriate NDK Support Package (NSP) for the various supported platforms separately.

SYS/BOIS:  Previous versions of SYS/BIOS were called DSP/BIOS. The new name reflects that the kernel can also be use on processors other than DSPs.
