The amba_pv::amba_pv_control class provides support for AMBA protocol additional control information. The additional control information supported by the AMBA protocol and modeled by this class includes:

The class provides the API:

class amba_pv_control {
/* Construction */
public:

    amba_pv_control();    

/* Accessors */    
    /* Transaction ID */ 
    void set_id(unsigned int);
    unsigned int get_id() const;

    /* Protection unit support     */
    void set_privileged(bool /* privileged */ = true);
    bool is_privileged() const;
    void set_non_secure(bool /* non_secure */ = true);    
    bool is_non_secure() const;    
    void set_instruction(bool /* instruction */ = true);    
    bool is_instruction() const;

    /* Atomic access support */    
    void set_exclusive(bool /* exclusive */ = true);    
    bool is_exclusive() const;    
    void set_locked(bool /* locked */ = true);
    bool is_locked() const;

    /* Cache support */    
    void set_bufferable(bool /* bufferable */ = true);    
    bool is_bufferable() const;
    void set_cacheable(bool /* cacheable */ = true);
    bool is_cacheable() const;
    void set_read_allocate(bool /* read_allocate */ = true);
    bool is_read_allocate() const;    
    void set_write_allocate(bool /* write_allocate */ = true);
    bool is_write_allocate() const;
};

The amba_pv::amba_pv_resp_t type defines the AMBA-PV protocol response type. Defined values are:

This is the type definition (in the amba_pv namespace) for the AMBA-PV protocol transaction type. The amba_pv_types.h file contains:

struct amba_pv_protocol_types {
    typedef tlm::tlm_generic_payload tlm_payload_type;
    typedef tlm::tlm_phase tlm_phase_type;
};
