| 11 | # This file contains the python classes required to define a generic hardware |
|---|
| 12 | # architecture for the ALMOS-MK operating system. |
|---|
| 13 | # It handle 4 types of objects: clusters, cores, devices and irqs. |
|---|
| 14 | # - The number of cluster is variable (can be one). |
|---|
| 15 | # - The cluster topology can be a 2D mesh or a simple 1D array. |
|---|
| 16 | # - The number of cores per cluster is variable (can be zero). |
|---|
| 17 | # - The number of addressable devices per cluster is variable. |
|---|
| 18 | # - The size of the physical memory bank per cluster is variable. |
|---|
| 19 | # An adressable device can be a physical memory bank or a peripheral. |
|---|
| 20 | # Each cluster cover a fixed size segment in physical address space, |
|---|
| 21 | # that is defined by (PADDR_WIDTH - X_WIDTH - Y_WIDTH) |
|---|
| 22 | ######################################################################################### |
|---|
| 23 | # Implementation Note: |
|---|
| 24 | # The objects used to describe an architecture are distributed in the python structure: |
|---|
| 25 | # For example the set of cores and the set of devices are split in several subsets |
|---|
| 26 | # (one subset of cores and one subset of devices per cluster). |
|---|
| 27 | # In the generated C binary data structure, all objects of same type |
|---|
| 28 | # are stored in a linear array (one single array for all cores for example). |
|---|
| 29 | # For all objects, we compute and store in the python object a "global index" |
|---|
| 30 | # corresponding to the index in this global array, and this index can be used as |
|---|
| 31 | # a pseudo-pointer to identify a specific object of a given type. |
