| 8 | // This file define a TSAR cluster architecture with virtual memory: |
---|
[428] | 9 | // - It uses two virtual_dspin_router as distributed global interconnect |
---|
| 10 | // - It uses four dspin_local_crossbar as local interconnect |
---|
[345] | 11 | // - It uses the vci_cc_vcache_wrapper |
---|
| 12 | // - It uses the vci_mem_cache |
---|
| 13 | // - It contains a private RAM with a variable latency to emulate the L3 cache |
---|
| 14 | // - It can contains 1, 2 or 4 processors |
---|
| 15 | // - Each processor has a private dma channel (vci_multi_dma) |
---|
| 16 | // - It uses the vci_xicu interrupt controller |
---|
[396] | 17 | // - The peripherals MTTY, BDEV, FBUF, MNIC and BROM are in cluster (0,0) |
---|
[428] | 18 | // - The Multi-TTY component controls up to 15 terminals. |
---|
[345] | 19 | // - Each Multi-DMA component controls up to 8 DMA channels. |
---|
| 20 | // - The DMA IRQs are connected to IRQ_IN[8]...IRQ_IN[15] |
---|
| 21 | // - The TTY IRQs are connected to IRQ_IN[16]...IRQ_IN[30] |
---|
| 22 | // - The BDEV IRQ is connected to IRQ_IN[31] |
