Abstract: A method for resource allocation in a cloud environment detects a metrics parameter of at least a first virtual machine among a plurality of virtual machines inside a virtual system in the cloud environment; calculates a key performance indicator according to the metrics parameter, the key performance indicator indicating running status of at least the first virtual machine; and reallocates resources among at least the first virtual machine and other virtual machines within the virtual system based on the key performance indicator through the cloud environment in response to the key performance indicator indicating that at least the first virtual machine is overloaded.

Abstract: It is disclosed herein that a system for reducing video data memory in VGA-to-TV converters that convert computer video signals to TV compliant signals for display on regular TV screens. By closely tracking two pointers, one being a write pointer responsible for writing incoming video data into the video data memory and the other being a read pointer responsible for reading out the stored video data in the video data memory, the memory is efficiently used for buffering the video data. To ensure that the read pointer always retrieves the valid video data at its own speed, an address monitoring process is provided to monitor the address difference between the write pointer and the read pointer. When the monitoring process detects that the read pointer may soon surpass the write pointer, a control process is placed on the write pointer to prevent the read pointer from passing over the write pointer.
