Aiming at the problem that PC platform nuclear spectrum analysis software has many shortages, such as high cost, large value, limited application range, etc, a kind of nuclear energy spectrum analysis system with ARM/DSP architecture as the core is designed and realized. The Devkit8500D evaluation board embedded DM3730 of TI company is used as the development and test platform for the system. It uses the Linux operating system, through scientific calculation software Octave loading and processing original nuclear spectrum data and the energy spectrum visualization displays on the TFT LCD screen. For the Octave transplantation , adding the necessary dependent libraries and header files, using cross tool chain to compile Octave, with the help of ext2 format TF card to transplant it into the Devkit8500D platform. The test results of nuclear spectrum data show that the scheme of system has data processing with high efficiency, good real-time performance, good stability and portability, and a strong practical value.
