摘要:
A system including a host coupled to a memory device and a peripheral controller device. The host is coupled to the peripheral controller device via a bus having a plurality of general purpose signal lines to carry time-multiplexed address, data, and control information. The peripheral controller device performs direct memory access (DMA) transactions with the memory device via the host and the bus.

A system having a bus coupled to a host and a peripheral controller device each coupled to a bus. The bus includes a plurality of general purpose signal lines to carry time-multiplexed address, data, and control information. The peripheral controller device communicates with the host over the bus to control devices such as parallel port controllers, serial port controllers, super I/O controllers, floppy disk controllers, keyboard controllers and memory devices.

A system including a host, a peripheral controller device, and a bus master device each coupled to a bus having a plurality of general purpose signal lines for carrying time-multiplexed address, data, and control information. The bus master device communicates with the host and the peripheral controller device via the bus.
摘要:
A method and apparatus which may be used for direct memory access (DMA) acknowledges. A method of acknowledging a request for access to a bus from a bus agent access involves receiving a request for access to the bus and generating a request acknowledge signal. The request acknowledge is generated on a multiplexed bus in response to the request for access to the bus.

A system having a bus coupled to a host and a memory device. The bus may include a plurality of general purpose signal lines to carry time-multiplexed address, data, and control information. The memory device may store system start-up information and communicate this information with the host over the bus.

The present invention is a method and system to automatic loading program on a medium into memory for execution. In one embodiment, a mode word is configured. The insertion of the medium into a drive is detected based on the mode word. A program on the medium is started when insertion is detected. In another embodiment, a polling circuit in a chipset detects the insertion of the medium into the drive. A status bit is checked in response to an interrupt generated by the polling circuit. A flag in a memory is updated based on the status bit. A poll request by an operating system is responded.

This disclosure pertains to device-monitoring systems, and in particular (but not exclusively) to detecting and deterring unauthorized use of electronic systems at distinct locations and during specific time periods. An apparatus consistent with the present disclosure includes logic, at least partially implemented in hardware, to receive an entrance message. The entrance message may include at least one policy for the manner to which a device is to be operated when present within a device restricted area. The apparatus may also include logic to send an acknowledgement notification to indicate receipt of the entrance message and an agreement to abide by the at least one policy. Furthermore, the apparatus may also include logic to detect an attempt to execute an action contrary to the at least one policy.

A device, method, and computer-readable medium are disclosed. In one embodiment, the device includes an inbound port to receive information from an information retrieval peripheral. The device also includes an outbound port to send information to a local computing device. The device includes masking logic to cause the local computing device to recognize the portable security device as at least one of a plurality of endpoint devices. The device also includes data obfuscation logic that is capable of obfuscating simple data format data, received from the information retrieval peripheral, obfuscating that data into a non-simple data format, and sending the obfuscated data to the local computing device. The non-simple data format includes at least one frame of video.

Embodiments of methods and systems for improving boot-up time in computer systems utilize RAM in devices separate from the main memory, normally dedicated to another function, to provide a stack and temporary storage during BIOS execution, enabling BIOS to call subroutines and execute in a multi-threading fashion, speeding system boot-up.
摘要:
A circuit, method, and system are disclosed. In one embodiment the circuit comprises a ring oscillator circuit having a plurality of delay elements, the ring oscillator circuit to generate a clock signal frequency, a checker circuit to compare a count of clock signal oscillations observed per complete loop of the ring oscillator circuit to a reference count, and to set a flag signal if the clock signal oscillation count is above a high threshold amount or below a low threshold amount.
