Abstract
Methods and systems are provided for enabling early display activation during a boot cycle in a computing system utilizing an accelerated processing unit (APU) with a memory buffer. During system memory initialization, display data is stored in the memory buffer of the APU and retrieved for presentation on a coupled display device, providing real-time visual feedback while memory training is performed. Memory training data is generated and saved to allow faster system initialization during subsequent boot cycles.
Claims20
A method comprising:
- initializing a system memory during a boot cycle of a computing system having an accelerated processing unit (APU) communicatively coupled to a general processing core;
- storing display data in a memory buffer of the APU;
- and
- during the initializing of the system memory, retrieving the stored display data from the memory buffer of the APU for presentation on a display device of the computing system.
A computing system, comprising:
- an accelerated processing unit (APU) having a memory buffer;
- a general processing core communicatively coupled to the APU;
- and
- a system memory;
- wherein the computing system is configured to:
- initialize the system memory during a boot cycle;
- store display data in the memory buffer of the APU;
- and
- during the initialization of the system memory, retrieve the stored display data from the memory buffer for presentation on a display device that is communicatively coupled to the computing system.
A bootloader processor configured to, during a boot cycle of a computing system:
- initialize a system memory of the computing system;
- store display data in a memory buffer of an accelerated processing unit (APU), wherein the APU is communicatively coupled to a general processing core of the computing system;
- and
- during initialization of the system memory, retrieve the stored display data from the memory buffer of the APU for presentation on a display device communicatively coupled to the computing system.
