| 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) |

---|
| 28 | // - the multi-channel network controller (MNIC) |
---|
| 29 | // - the multi-channel chained buffer dma controller (CDMA) |
---|
| 30 | // - the multi-channel tty controller (MTTY) |
---|

| 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. |
