| 8 | // This file define a generic TSAR architecture without virtual memory. |
---|
| 9 | // - It uses the vci_vgmn as global interconnect |
---|
| 10 | // - It uses the vci_local_crossbar as local interconnect |
---|
| 11 | // - It uses the vci_cc_xcache (No MMU) |
---|
| 12 | // The physical address space is 32 bits. |
---|
| 13 | // The number of clusters cannot be larger than 256. |
---|
| 14 | // The three parameters are |
---|
| 15 | // - xmax : number of clusters in a row |
---|
| 16 | // - ymax : number of clusters in a column |
---|
| 17 | // - nprocs : number of processor per cluster |
---|
| 18 | // |
---|
| 19 | // Each cluster contains nprocs processors, one Memory Cache, |
---|
| 20 | // and one XICU component. |
---|
| 21 | // The peripherals BDEV, CDMA, FBUF, MTTY and the boot BROM |
---|
| 22 | // are in the cluster containing address 0xBFC00000. |
---|
| 23 | // - The bdev_irq is connected to IRQ_IN[0] |
---|
| 24 | // - The cdma_irq is connected to IRQ_IN[1] |
---|
| 25 | // - The tty_irq[i] is connected to IRQ_IN[i+2] |
---|
| 26 | // For all clusters, the XICU component contains nprocs timers. |
---|
| 27 | // |
---|
| 28 | // As we target up to 256 clusters, each cluster can contain |
---|
| 29 | // at most 16 Mbytes (in a 4Gbytes address space). |
---|
| 30 | // There is one MEMC segment and one XICU segment per cluster. |
---|
| 31 | // - Each memory cache contains 8 Mbytes. |
---|
| 32 | // - The Frame buffer contains 4 Mbytes. |
---|
| 33 | // - The Boot ROM contains 1 Mbytes |
---|
| 34 | // |
---|
| 35 | // General policy for 32 bits address decoding: |
---|
| 36 | // To simplifly, all segments base addresses are aligned |
---|
| 37 | // on 64 Kbytes addresses. Therefore the 16 address MSB bits |
---|
| 38 | // define the target in the direct address space. |
---|
| 39 | // In these 16 bits, the (x_width + y_width) MSB bits define |
---|
| 40 | // the cluster index, and the 8 LSB bits define the local index: |
---|
| 41 | // |
---|
| 42 | // | X_ID | Y_ID |---| L_ID | OFFSET | |
---|
| 43 | // |x_width|y_width|---| 8 | 16 | |
