Macro Definition Documentation

ARCHITECTURE_WORD_BITS

#define ARCHITECTURE_WORD_BITS   <NUM>

Size of a word in bits.

Depending on architecture, this can have a value of 8, 16, or 32

Definition at line 42 of file architecture.h.

ARCHITECTURE_WORD_BYTES

#define ARCHITECTURE_WORD_BYTES   <NUM>

Size of a word in bytes.

Depending on architecture, this can have a value or 1, 2, or 4.

Definition at line 48 of file architecture.h.

WORD_ALIGNED

#define WORD_ALIGNED   __attribute__((aligned(ARCHITECTURE_WORD_BYTES)))

Type qualifier to use to align data on word boundaries.

Use like this:

char WORD_ALIGNED thread_stack[THREAD_STACKSIZE_DEFAULT];

Definition at line 88 of file architecture.h.

Typedef Documentation

sword_t

typedef int<num> _t sword_t

Word sized signed integer.

Synonym to int8_t, int16_t or int32_t depending on architecture

Definition at line 62 of file architecture.h.

uword_t

typedef uint<num> _t uword_t

Word sized unsigned integer.

Synonym to uint8_t, uint16_t or uint32_t depending on architecture

Definition at line 55 of file architecture.h.
