Functions Documentation

function snrt_l1_next

inline void * snrt_l1_next()

function snrt_l3_next

inline void * snrt_l3_next()

function snrt_l1alloc

inline void * snrt_l1alloc(
    size_t size
)

Allocate a chunk of memory in the L1 memory.

Parameters:

)

Override the L1 allocator next pointer.

function snrt_l3alloc

inline void * snrt_l3alloc(
    size_t size
)

Allocate a chunk of memory in the L3 memory.

Parameters:

• size number of bytes to allocate
