Data Structures

struct  arm_shared_t
 

Typedefs

typedef struct arm_shared_t arm_shared
 

Functions

void * arm_shared_init (arm_shared *handle, const uint32_t address, const uint32_t length)
 
void arm_shared_close (arm_shared *handle)
 

Detailed Description

Do not use. Low-level functions for MMIO access to the FPGA fabric.

This library gives low-level memory-mapped access to the hardware units in the FPGA.

This is an internal library and should not be directly used.
