Chapter 6 Software Resources and Processing Time
6. 2 Software Resources
In the EEL, program areas corresponding to parts of the library to be used, RAM areas for variables to be used in
the library, and RAM areas for work area (self-RAM) are used to assign an appropriate program to the user area.
Also, since the FDL will be used, the EEL must have a separate area for use by the FDL.
Tables 6-3 and 6-4 list required software resources ^{Note 1, 2}. Figures 6-2 and 6-3 show the images of allocating software
resources to the RAM.
