Hi, I am trying to write a multi-processor platform with private program memories, and I was trying to figure out if this was possible with SOCLIB. I made a try with 2 Mips in a first phase, with two associated mapping tables. The difference between both mappings is the MEMORY address, 0x10000000 for Mips0 and 0x20000000 for Mips1. I created two loaders taking different binaries, the reset section of the first jumps to 0x10xxxx and the second jumps to 0x20xxx.

Loader loader0("MJPEG0.x");

VciRam<vci_param> vcimultiram0("vcimultiram0", IntTab(0,0), maptab, loader0);

Loader loader1("MJPEG1.x");

VciRam<vci_param> vcimultiram1("vcimultiram1", IntTab(1,0), maptab1, loader1);

MJPEG0.x:

211735 bfc00020: 3c1b1001 lui k1,0x1001

211736 bfc00024: 277bf360 addiu k1,k1,-3232

MJPEG1.x:

202290 bfc00020: 3c1b2001 lui k1,0x2001

202291 bfc00024: 277bb820 addiu k1,k1,-18400

However, when I execute the simulation, I see that cache1 seems to execute the reset section of MJPEG0.x.

cache0 PC: 0xbfc00020 NPC: 0xbfc00024 Ins: 0x3c1b1001

cache0 PC: 0xbfc00024 NPC: 0xbfc00028 Ins: 0x277bf360

cache1 PC: 0xbfc00020 NPC: 0xbfc00024 Ins: 0x3c1b1001

cache1 PC: 0xbfc00024 NPC: 0xbfc00028 Ins: 0x277bf360

Did I do something wrong?

Thank you Alexandre

When I execute the caba-vgmn-vcache_multi_timer-iss2_mipsel platform, the simulation results a segmentation fault.

Existe t-il une documentation sur ces modes d'accès aux données ?
