---|
| 9 | // The physical address space is 40 bits. |
---|

---|
| 12 | // The number of processors per cluster cannot be larger than 8. |

---|
| 14 | // - It uses four dspin_local_crossbar per cluster as local interconnect |
---|
| 15 | // - It uses two virtual_dspin routers per cluster as global interconnect |
---|
| 16 | // - It uses the vci_cc_vcache_wrapper |
---|
| 17 | // - It uses the vci_mem_cache |
---|
| 18 | // - It contains one vci_xicu per cluster. |
---|
| 19 | // - It contains one vci_multi_dma per cluster. |
---|
| 20 | // - It contains one vci_simple_ram per cluster to model the L3 cache. |
---|
| 21 | // |
---|
| 22 | // The communication between the MemCache and the Xram is 64 bits. |
---|
| 23 | // |
---|
| 24 | // All clusters are identical, but the cluster 0 (called io_cluster), |
---|
| 25 | // contains 6 extra components: |
---|
| 26 | // - the boot rom (BROM) |
---|
| 27 | // - the disk controller (BDEV) |
---|
| 28 | // - the multi-channel network controller (MNIC) |
---|
| 29 | // - the multi-channel chained buffer dma controller (CDMA) |
---|
| 30 | // - the multi-channel tty controller (MTTY) |
---|
| 31 | // - the frame buffer controller (FBUF) |
---|
| 32 | // |
---|

---|
| 34 | // defined in files tsar_xbar_cluster.* (with * = cpp, h, sd) |

| 36 | // The IRQs are connected to XICUs as follow: |
---|
| 37 | // - The IRQ_IN[0] to IRQ_IN[7] ports are not used in all clusters. |
---|
| 38 | // - The DMA IRQs are connected to IRQ_IN[8] to IRQ_IN[15] in all clusters. |
---|
| 39 | // - The TTY IRQs are connected to IRQ_IN[16] to IRQ_IN[30] in I/O cluster. |
---|
| 40 | // - The BDEV IRQ is connected to IRQ_IN[31] in I/O cluster. |
---|

---|

---|
| 43 | // by this top.cpp file. They must be defined in the hard_config.h file : |
---|
| 44 | // - CLUSTER_X : number of clusters in a row (power of 2) |
---|
| 45 | // - CLUSTER_Y : number of clusters in a column (power of 2) |

---|
| 50 | // - NB_NIC_CHANNELS : number of NIC channels in I/O cluster (< 9) |
---|
| 51 | // |
---|

---|
| 53 | // and can be directly defined in this top.cpp file: |
---|
| 54 | // - XRAM_LATENCY : external ram latency |

| 60 | // - L1_DSETS |
---|
| 61 | // - FBUF_X_SIZE : width of frame buffer (pixels) |
---|
| 62 | // - FBUF_Y_SIZE : heigth of frame buffer (lines) |
---|
| 63 | // - BDEV_SECTOR_SIZE : block size for block drvice |
