32 | Memory is typically a limited resource in real-time |
---|
33 | embedded systems, therefore, RTEMS can be configured to utilize |
---|
34 | the minimum amount of memory while meeting all of the |
---|
35 | applications requirements. Worksheets are provided which allow |
---|
36 | the RTEMS application developer to determine the amount of RTEMS |
---|
37 | code and RAM workspace which is required by the particular |
---|
38 | configuration. Also provided are the minimum code space, |
---|
39 | maximum code space, and the constant data space required by |
---|
40 | RTEMS. |

47 | RTEMS requires a small amount of memory for its |
---|
48 | private variables. This data area must be in RAM and is |
---|
49 | separate from the RTEMS RAM Workspace. The following |
---|
50 | illustrates the data space required for all configurations of |
---|
51 | RTEMS: |

62 | A maximum configuration of RTEMS includes the core |
---|
63 | and all managers, including the multiprocessing manager. |
---|
64 | Conversely, a minimum configuration of RTEMS includes only the |
---|
65 | core and the following managers: initialization, task, interrupt |
---|
66 | and fatal error. The following illustrates the code space |
---|
67 | required by these configurations of RTEMS: |

79 | The RTEMS Code Space Worksheet is a tool provided to |
---|
80 | aid the RTEMS application designer to accurately calculate the |
---|
81 | memory required by the RTEMS run-time environment. RTEMS allows |
---|
82 | the custom configuration of the executive by optionally |
---|
83 | excluding managers which are not required by a particular |
---|
84 | application. This worksheet provides the included and excluded |
---|
85 | size of each manager in tabular form allowing for the quick |
---|
86 | calculation of any custom configuration of RTEMS. The RTEMS |
---|
87 | Code Space Worksheet is below: |
