10 | # This file contains the classes required to define a mapping for the GIET_VM. |
---|
11 | # - A 'Mapping' contains a set of 'Cluster' (hardware architecture) |
---|
12 | # a set of 'Vseg' (kernel glogals virtual segments) |
---|
13 | # a set of 'Vspace' (one or several user applications) |
---|
14 | # - A 'Cluster' contains a set of 'Pseg' (physical segments in cluster) |
---|
15 | # a set of 'Proc' (processors in cluster) |
---|
16 | # a set of 'Periph' (peripherals in cluster) |
---|
17 | # - A 'Vspace' contains a set of 'Vseg' (user virtual segments) |
---|
18 | # a set of 'Task' (user parallel tasks) |
---|
19 | # - A 'Periph' contains a set of 'Irq' (only for XCU and PIC types ) |
---|
20 | ######################################################################################## |
---|
21 | # Implementation Note |
---|
22 | # The objects used to describe a mapping are distributed in the PYTHON structure: |
---|
23 | # For example the psegs set is split in several subsets (one subset per cluster), |
---|
24 | # or the tasks set is split in several subsets (one subset per vspace), etc... |
---|
25 | # In the C binary data structure used by the giet_vm, all objects of same type |
---|
26 | # are stored in a linear array (one single array for all psegs for example). |
---|
27 | # For all objects, we compute and store in the PYTHON object itself a "global index" |
---|
28 | # corresponding to the index in this global array, and this index can be used as |
---|
29 | # a pseudo-pointer to identify a specific object of a given type. |
