How to talk with milkymist cores

From Milkymist Wiki

Basically Memory-mapped I/O http://wikimedia.org/wikipedia/en/wiki/MMIO

Some sniptes

/* PLEASE notice the use of volatile */

volatile unsigned int *my_peripheral;

/* peripheral memory mapped at 0xc0001004 */

my_peripheral = (unsigned int *)0xc0001004;

/* write word to peripheral */

• my_peripheral = 0xbaadf00d;

/* read word from peripheral */

printf("Result: %08x\n", *my_peripheral);

also

1. define MM_READ(reg) (*((volatile unsigned int *)(reg)))
2. define MM_WRITE(reg, val) *((volatile unsigned int *)(reg)) = val
