Description: cmd 文件用于DSP 代码的定位。由于DSP 的编译器的编译结果是未定位的，
DSP没有操作系统来定位执行代码，每个客户设计的DSP 系统的配置也不尽相同，因此需要用
户自己定义代码的安装位置。安装位置是指，编译完成的代码是存放在dsp的那个位置，程序空间RAM或者数据空间RAM，起始地址以及长度。-cmd file for the positioning of DSP code. As the DSP of the compiler to compile the results are not targeted, DSP is not operating system to locate the implementation of the code, each custom design the configuration of the DSP system are not the same, so the definition of the needs of the user' s own code of the installation location. Refers to the installation location, the compiler completed dsp code is stored in that location, the program RAM space or data space RAM, the start address and length. Platform: |

Description: Rapid Controller Prototyping (RCP) requires two components:
a Computer Aided Control System Design (CACSD)
software and a dedicated hardware with a hard real-time
operating system. The software should allow to perform all
phases of control system design (specification, modelling and
identification, control design, simulation, implementation and
verification) in the same environment. A graphcal application
allows the user to create models for dynamic systems simply
by connecting blocks from available libraries. Among others,
some blocks implement linear systems given as transfer
functions or state-space realizations both in continuous and
discrete time. An integrated code generator allows to directly
create code from the graphical scheme. The COMEDI project
([1]) provides the drivers to interface the system with the real
plants. Platform: |
