Name of the IDE from Texas Instruments originally intended for DSP developers, later extended to cover almost all processors offered by TI. Currently contains Eclipse based IDE and toolchains.
Code Composer Studio in the official name given by Texas Instruments to their set of development tools: Integrated Development Environment with debugging tools. Initially the IDE was native Windows application made by TI, but from some time it is Eclipse based. Contains set of toolchains (assembler, c/c++ compilers, linkers, libraries, some real-time operating systems for DSP or ARM) as well.
Well known by any software engineer who developed on C64x or C67x DSP families or MSP430 family.
Probably only tool able to handle TI's or Spectrum Digital JTAG emulators used as hardware debuggers for TI chips.
