Abstract
Systems and methods for providing accelerated loading of operating system and application programs upon system boot or application launch. In one aspect, a method for providing accelerated loading of an operating system comprises the steps of: maintaining a list of boot data used for booting a computer system; preloading the boot data upon initialization of the computer system; and servicing requests for boot data from the computer system using the preloaded boot data. The boot data may comprise program code associated with an operating system of the computer system, an application program, and a combination thereof. In a preferred embodiment, the boot data is retrieved from a boot device and stored in a cache memory device. In another aspect, the method for accelerated loading of an operating system comprises updating the list of boot data during the boot process, wherein updating comprises adding to the list any boot data requested by the computer system not previously stored in the list and/or removing from the list any boot data previously stored in the list and not requested by the computer system. In yet another aspect, the boot data is stored in a compressed format on the boot device and the preloaded boot data is decompressed prior to transmitting the preloaded boot data to the requesting system. In another aspect, a method for providing accelerated launching of an application program comprises the steps of: maintaining a list of application data associated with an application program; preloading the application data upon launching the application program; and servicing requests for application data from a computer system using the preloaded application data.

17. A method comprising:
-
maintaining a list of boot data used for booting a computer system, wherein at least a portion of said boot data is stored in compressed form on a boot device;
initializing a central processing unit of said computer system;
preloading said at least a portion of said boot data in compressed form from said boot device, prior to completion of the initialization of the central processing unit, to a memory;
accessing and decompressing said at least a portion of said boot data in said compressed form from said memory; and
utilizing said decompressed at least a portion of said boot data to boot said computer system, wherein said at least a portion of said boot data is compressed, to provide said at least a portion of said boot data in compressed form, and decompressed by a data compression engine. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A system comprising:
-
a processor;
a memory; and
a non-volatile memory device for storing logic code associated with the processor, wherein said logic code comprises instructions executable by the processor for maintaining a list of boot data used for booting the host system, at least a portion of said boot data is stored in compressed form in said non-volatile memory device, said at least a portion of said boot data in compressed form is preloaded into said memory prior to completion of the initialization of the central processing unit, and said preloaded at least a portion of boot data in compressed form is decompressed and utilized to boot said computer system; and
a data compression engine for providing said at least a portion of said boot data in compressed form by compressing said at least a portion of said boot data and decompressing said at least a portion of said boot data in compressed form to provide said decompressed at least a portion of boot data. - View Dependent Claims (28, 29, 30, 31, 32, 33)
