v34 v35 14 14 * '''External peripherals''': Accesses use virtual addresses if the MMU (Memory management Unit) is activated, or physical addresses if it is not. In this case, the physical address is computed as pbase = SEG_XXX_BASE + cluster_io << 32. 15 15 16 * '''Internal peripherals''': Accesses use virtual addresses, and the MMU must be activated. The peripheral virtual base address is computed as vbase = SEG_XXX_BASE + cluster_xy * CLUSTER_INCREMENT.16 * '''Internal peripherals''': Accesses use virtual addresses, and the MMU must be activated. The peripheral virtual base address is computed as vbase = SEG_XXX_BASE + cluster_xy * PERI_CLUSTER_INCREMENT. 17 17 18 The SEG_XXX_BASE , X_IO, Y_IO, and CLUSTER_INCREMENT vatiables must be defined in the ''hard_config.h" file.18 The SEG_XXX_BASE , X_IO, Y_IO, and PERI_CLUSTER_INCREMENT variables must be defined in the ''hard_config.h" file. 19 19 20 20 === [wiki:bdv_driver BDV (Block Device controller)]
