| 10 | # This python script defines a specific instance of "tsar_generic_iob" architecture |
|---|
| 11 | # for the ALMOS-MKH operating system. It is used to generate the "hard_config.h" file, |
|---|
| 12 | # used to configure the hardware architecture, and the "arch_info.bin" file, used by |
|---|
| 13 | # the ALMOS-MK bootloader. |
|---|
| 14 | # |
|---|
| 15 | # The constructor prototype format is imposed by the genarch.py application, |
|---|
| 16 | # and should not be modified. |
|---|
| 17 | # |
|---|
| 18 | # The "tsar_generic_iob" architecture includes 7 external peripherals, accessed |
|---|
| 19 | # through an IOB components located in cluster [0,0] or in cluster [x_size-1, y_size-1]. |
|---|
| 20 | # Available peripherals are: TTY, IOC, FBF, ROM, NIC, CMA, PIC. |
|---|
| 21 | # All clusters contain (nb_cores) processors, one L2 cache, one XCU, and |
|---|
| 22 | # one optional hardware coprocessor connected to a MWMR controller. |
|---|
| 23 | # |
|---|
| 24 | # As the "tsar_generic_iob" architecture is generic, the following parameters |
|---|
| 25 | # are defined as constructor arguments and can be redefined in the Makefile when |
|---|
| 26 | # a new kernel image is generated : |
|---|
| 27 | # - x_size : number of clusters in a row (from 1 to 16) |
|---|
| 28 | # - y_size : number of clusters in a column (from & to 16) |
|---|
| 29 | # - nb_cores : number of processors per cluster (from 1 to 4) |
|---|
| 30 | # - nb_ttys : number of TTY channels (can be from 1 to 8) |
|---|
| 31 | # - nb_nics : number of NIC channels (from 1 to 2) |
|---|
| 32 | # - fbf_width : frame_buffer width = frame_buffer heigth |
|---|
| 33 | # - ioc_type : can be 'IOC_BDV','IOC_HBA','IOC_SDC', 'IOC_SPI','NONE' |
|---|
| 34 | # |
|---|
| 35 | # The following parameters are imposed by the "tsar_generic_iob" architecture: |
|---|
| 36 | # - devices_max : max number of devices per cluster |
|---|
| 37 | # - x_width : number of bits for x coordinate |
|---|
| 38 | # - y_width : number of bits for y coordinate |
|---|
| 39 | # - paddr_width : number of bits for physical address |
|---|
| 40 | # - p_width : number of bits for local processor index |
|---|
| 41 | # - irqs_per_core : number of input IRQs per processor |
|---|
| 42 | # - io_cxy : IO cluster identifier |
|---|
| 43 | # - boot_cxy : boot cluster identifier |
|---|
| 44 | # - cache_line : number of bytes in cache line (in 16,32,64) |
