8	// This file define a generic TSAR architecture, fully compatible
9	// with the VLSI Hardware prototype developped by CEA-LETI and LIP6
10	// in the framework of the SHARP project.
11	//
12	// The processor is a MIPS32 processor wrapped in a GDB server
13	// (this is defined in the tsar_leti_cluster).
14	//
15	// The main hardware parameters are the mesh size (X_SIZE & Y_SIZE),
16	// and the number of processors per cluster (NB_PROCS_MAX).
17	// The NB_PROCS_MAX parameter cannot be larger than 4.
18	// Others parameters are the frame buffer size, the disk controller type
19	// the number of TTY channels, the number of NIC channels.
20	//
21	// All external peripherals are located in cluster[X_SIZE-1][Y_SIZE-1],
22	// and are connected to an IO bus (implemented as a vci_local_crossbar):
23	// - DISK : block device controller
24	// - MNIC : multi-channel ethernet controller
25	// - MTTY : multi-channel tty controller
26	// - FBUF : frame buffer controller
27	// - IOPI : HWI to SWI translator
28	//
29	// This IO bus is directly connected to the north ports of the CMD/RSP
30	// routers in cluster[X_SIZE-1][Y_SIZE-1] through VCI/DSPIN wrappers.
31	// All other clusters in the upper row are empty: no processors, no ram.
32	// The X_SIZE parameter must be larger than 0, but no larger than 16.
33	// The Y_SIZE parameter must be larger than 1, but no larger than 16.
34	//
35	// We don't use an external ROM, as the boot code is (pre)loaded
36	// in RAM in cluster[0][0] at address 0x0.
37	//
38	// An optional RAMDISK of 32 Mbytes can be used in RAM of cluster[0][0].
39	//
40	// The physical address space is 40 bits.
41	// The 8 address MSB bits define the cluster index.
42	//
43	// Besides the processors, each cluster contains:
44	// - 5 L1/L2 DSPIN routers implementing 5 separated NOCs
45	// - 1 vci_mem_cache
46	// - 1 vci_xicu
47	// - 1 vci_simple_ram (to emulate the L3 cache).
48	//
49	// Each processor receives 4 consecutive IRQ lines from the local XICU.
50	// The number of PTI and WTI IRQs is bounded to 16.
51	//
52	// In all clusters, the MEMC IRQ line (signaling a late write error)
53	// is connected to XICU HWI[8]
54	//
55	// For all external peripherals, the hardware interrupts (HWI) are
56	// translated to write interrupts (WTI) by the iopic component:
57	// - IOPIC HWI[1:0] connected to IRQ_NIC_RX[1:0]
58	// - IOPIC HWI[3:2] connected to IRQ_NIC_TX[1:0]
59	// - IOPIC HWI[7:4] connected to IRQ_CMA_TX[3:0]]
60	// - IOPIC HWI[8] connected to IRQ_DISK
61	// - IOPIC HWI[15:9] unused (grounded)
62	// - IOPIC HWI[23:16] connected to IRQ_TTY_RX[7:0]]
63	// - IOPIC HWI[31:24] connected to IRQ_TTY_TX[7:0]]
64	//
65	// The cluster internal architecture is defined in file tsar_leti_cluster,
66	// that must be considered as an extension of this top.cpp file.

75	// - NB_CMA_CHANNELS : number of CMA channels in I/0 cluster (4 max)
76	// - NB_TTY_CHANNELS : number of TTY channels in I/O cluster (8 max)
77	// - NB_NIC_CHANNELS : number of NIC channels in I/O cluster (2 max)
78	// - FBUF_X_SIZE : number of pixels per line for frame buffer
79	// - FBUF_Y_SIZE : number of lines for frame buffer
80	// - XCU_NB_HWI : number of XCU HWIs (must be 16)

82	// - XCU_NB_WTI : number of XCU WTIs (must be 16)
83	// - XCU_NB_OUT : number of XCU output (must be 16)
84	// - USE_IOC_XYZ : IOC type (XYZ in HBA / BDV / SDC / RDK)
85	//
86	// Some other hardware parameters are not used when compiling the OS,
87	// and are only defined in this top.cpp file:
88	// - XRAM_LATENCY : external ram latency
89	// - L1_IWAYS : L1 cache instruction number of ways
90	// - L1_ISETS : L1 cache instruction number of sets
91	// - L1_DWAYS : L1 cache data number of ways
92	// - L1_DSETS : L1 cache data number of sets
93	// - DISK_IMAGE_NAME : pathname for block device disk image

97	// (=> the 24 LSB bits = 0, and the 16 MSB bits define the target)
98	// The (X_WIDTH + Y_WIDTH) MSB bits (left aligned) define
99	// the cluster index, and the LADR bits define the local index:
