A chip with IDE host and IDE slave and corresponding self-debugging function is provided. The chip simplifies IDE debugging of a chip, which comprises a front-end and a backend, by offering separate debugging modes for an IDE host and an IDE slave on the same chip. The front-end provides output data of an internal IDE slave or output data of an external IDE slave in response to a host debug enable signal. The backend is coupled to the front-end. The backend provides functions of an internal IDE ...

A low-power digital audio decoding and playing system and method for computing devices provides a low-cost, low power-consumption, long-battery-life audio playing and decoding system, which may be used to play compressed audio files of various formats. In one aspect, a computer system adapted to play audio files comprises a system CPU, memory, at least one drive comprising compressed audio data, and an audio controller coupled to the system CPU, memory and drive. The audio controller is adapted ...

A computer system includes a communication adapter that connects a plurality of virtualized servers to one or more support system devices. The communication adapter includes a master lock register, a processing device, a queue, and a multitude of adapter access registers. Upon initialization, a virtual server asserts ownership over the communication adapter by writing its identification into the master lock register, if the register is empty. Service requests by images are transmitted to the com...

A PC card control apparatus includes a PC card connector, a card detector and an interconnection switching circuit. The PC card connector is configured to provide connections for connecting one of a first PC card compliant with specific card standards and a card-adapting card for connecting a second PC card compliant with a different card standard to the PC card control apparatus. The card detector is configured to detect connection of the card-adapting card to the PC card control apparatus and ...

The present invention relates to a computer system and more particularly to a computer system which allows option controller cards for various input/output (I/O) devices to be added on the motherboard at minimum cost.

Method and system for performing hardware tasks using a hardware state machine and a processor is provided. The method includes, setting a breakpoint for a state machine state; running the processor in a parallel mode with the state machine; passing control to the processor after a breakpoint condition is encountered; performing a task, wherein the processor performs the task which was meant to be performed by the state machine; and transferring control back to the state machine after the proces...

Power conservation via DRAM access reduction is provided by a buffer/mini-cache selectively operable in a normal mode and a buffer mode. In the buffer mode, entered when CPUs begin operating in low-power states, non-cacheable accesses (such as generated by a DMA device) matching specified physical address ranges are processed by the buffer/mini-cache, instead of by a memory controller and DRAM. The buffer/mini-cache processing includes allocating lines when references miss, and returning cached ...
