Peripheral and Interface Components
Verification and testing
The AMBAPVValueState2SGValueState64 component has been tested as part of the SystemC
Export example systems. These systems can be found in %PVLIB_HOME%\examples\SystemCExport.
On Linux, look in the $PVLIB_HOME/examples/SystemCExport directory.
Performance
The AMBAPVValueState2SGValueState64 component is not expected to significantly affect
the performance of a PV system.
Library dependencies
The AMBAPVValueState2SGValueState64 component has no dependencies on external
libraries.
5.3.17 SystemC classes
This section describes SystemC classes used in the AMBAPV protocol behaviors, and which
are part of the AMBA TLM PV library for OSCI TLM 2.0.
• Class amba_pv::amba_pv_control
• amba_pv::amba_pv_resp_t on page 5-39.
Class amba_pv::amba_pv_control
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:
• protection units
• exclusive access and locked access mechanisms
• system-level caches.
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;
