Abstract: A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off state. The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system. The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive. Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected. The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems. The suspend/resume/standby feature is implemented at a low cost using many standard components.

Abstract: A digital data handling system handling display signal streams has a video processor which is capable of high performance due to vector processing and special addressing modes. The video processor is a single VLSI device having a plurality of processors, each of which has associated instruction and data caches, which are joined together by a wide data bus formed on the same substrate as the processors.

Abstract: Advantage is taken of Very Large Scale Integrated (VLSI) circuit design and manufacture to provide, in a digital data handling system handling display signal streams, a video processor which is capable of high performance due to vector processing and special addressing modes. The video processor has, on a single VLSI device, a plurality of processors which cooperate for generating video signal streams and which employ distinctive addressing modes for memory elements of the device. Each of the plurality of processors has associated instruction and data caches, which are joined together by a wide data bus formed on the same substrate as the processors, and further has registers for controlling access, and the modes of access, to data held in memory.

Abstract: A desktop computer system having the capability to suspend and resume the state of the computer system. The suspended system state is saved to the system hard file such that system power may be removed, effectively allowing a system suspend requiring no power from the power supply.
