Abstract
A system for programming at least a controller chip is disclosed. The system includes a programming apparatus and at least a programmable device mounted on the programming apparatus. The programming apparatus has at least a first connection interface and a micro-controller. The programmable device has the monitor controller chip mounted thereon and a second connection interface coupled between the first connection interface and the controller chip. The micro-controller controls the programming of the controller chip.
Claims19
A display controller chip utilized for controlling a display device, the display controller chip comprising:
- a non-volatile memory for storing program codes;
- an interface for communicating data and instructions;
- a micro-controller unit (MCU) for executing the program codes stored in the non-volatile memory to control operation of the display device;
- a control circuit, coupled to the interface, for selectively enabling and disabling the MCU, wherein the control circuit receives an instruction from the interface to disable the MCU when the non-volatile memory is being programmed;
- a write buffer;
- and
- a write control circuit, coupled to the interface, the write buffer and the non-volatile memory, for storing program codes received via the interface to the write buffer and writing program codes buffered in the write buffer to the non-volatile memory for programming the non-volatile memory.
A system for programming at least one controller chip utilized for controlling a peripheral device, the system comprising:
- a programming apparatus comprising:
- at least a first connection interface;
- and
- a micro-controller unit (MCU);
- and
- at least a programmable device, mounted on the programming apparatus, having the controller chip mounted thereon and a second connection interface coupled between the first connection interface and the controller chip;
- wherein the micro-controller unit controls the programming of the controller chip.
A method for programming a display controller chip utilized for controlling a display device, the method comprising:
- providing the display controller chip with:
- a non-volatile memory for storing program codes;
- an interface for communicating data and instructions;
- a micro-controller unit (MCU) for executing the program codes stored in the non-volatile memory to control operation of the display device;
- and
- a write buffer;
- receiving an instruction from the interface to disable the MCU;
- and
- storing program codes received via the interface to the write buffer, and writing program codes buffered in the write buffer to the non-volatile memory for programming the non-volatile memory.
