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 | // - Each memory cache contains 9 Mbytes. |
---|
31 | // - The Frame buffer contains 2 Mbytes. |
---|
32 | // - The Boot ROM contains 1 Mbytes. |
---|
33 | // |
---|
34 | // General policy for 32 bits address decoding: |
---|
35 | // To simplifly, all segments base addresses are aligned |
---|
36 | // on 1 Mbyte addresses. Therefore the 12 address MSB bits |
---|
37 | // define the target in the direct address space. |
---|
38 | // In these 12 bits, the (x_width + y_width) MSB bits define |
---|
39 | // the cluster index, and the 4 LSB bits define the local index: |
---|
40 | // |
---|
41 | // | X_ID | Y_ID |---| L_ID | OFFSET | |
---|
42 | // |x_width|y_width|---| 4 | 20 | |
