Abstract
A bus system is provided. A bus system includes a slave functional block and a master functional block. The master functional block transmits a first command to the slave functional block. The slave functional block includes a first bus protector. The first bus protector receives the first command on behalf of the slave functional block and transmits a dummy signal corresponding to the first command to the master functional block in response to the slave functional block being in a state of not being able to receive the first command or not being able to transmit a response signal corresponding to the first command.
Claims20
A bus system, comprising:
- a slave functional block;
- and
- a master functional block that transmits a first command to the slave functional block,
- wherein the slave functional block includes a first bus protector, which receives the first command on behalf of the slave functional block and transmits a dummy signal corresponding to the first command to the master functional block when the slave functional block is in a state of not being able to receive the first command or not being able to transmit a response signal corresponding to the first command.
A bus system, comprising:
- a bus to which a plurality of functional blocks are connected;
- and
- a system manager,
- wherein, if an operation of a first slave functional block, which is one of the plurality of functional blocks, is stopped and a first command for the first slave functional block does not exist on the bus, the system manager resets the first slave functional block.
A bus system, comprising:
- a first slave functional block including a first bus protector;
- a second slave functional block including a second bus protector;
- and
- a master functional block that transmits a first command to the first slave functional block and transmits a second command to the second slave functional block,
- wherein, when the first slave functional block is in a state of not being able to receive the first command or not being able to transmit a response signal corresponding to the first command, the first bus protector receives the first command on behalf of the first slave functional block and transmits to the master functional block a first dummy signal corresponding to the first command, and
- wherein the second slave functional block transmits a response signal corresponding to the second command to the master functional block.
