Abstract: A processor circuit having reduced power consumption includes an analog front end operative to receive an analog signal supplied to the processor circuit and to generate a digital signal indicative of the analog signal. The processor further includes a digital back end operative to generate a digital output signal as a function of the digital signal generated by the analog front end. A buffer is coupled between the analog front end and the digital back end. In a first mode of operation, the digital back end operates at a substantially same data rate as the analog front end and the buffer is bypassed. In a second mode of operation, the digital back end operates at a higher data rate than the analog front end and the buffer is used to store outputs of the analog front end.

Abstract: Systems, methods, and computer-readable media provide for notification of power-on self-test (POST) data using an output device that is externally connected to a target computer system undergoing the POST via a data cable. Embodiments include a data transport module having an interface for receiving POST data from a debug module within the firmware of the target computer system and a notification application executed on the output device. The POST data transport module receives POST data and writes it to one or more hardware registers associated with an external port of the target computer system. The POST data is transferred to the data cable from the hardware registers and is received from the cable by the notification application of the output device. The notification application generates a notification corresponding to the received POST data and displays the notification on a display of the output device.

Abstract: The tension between fmax and Tco in a specialized processing block of a programmable integrated circuit device can be reduced by providing variable delays on the clock inputs of the pipeline registers within the specialized processing block. This allows the introduction of beneficial skew that allows slower functions to be performed within the specialized processing block rather than outside the block, thereby reducing Tco, without slowing down the clock—i.e., without reducing fmax. This technique may also apply to other specialized blocks such as memory.

Abstract: The present invention relates to a portable information apparatus which can realize electrical power for a longer period of time. Under the condition that the suspending mode is set, when an exclusive key is manipulated, a switch monitoring circuit detects this condition and issues an interruption to the CPU. In this timing, the CPU supplies the necessary electrical power to the CD-ROM controller, CD-ROM drive and audio circuit which are required for reproduction of CD. Thereby, a CD can be reproduced under the suspending mode.

The memory access system includes a flash memory, a CPU, a peripheral component interconnect (PCI) slave, an address converter and a flash memory controller. The flash memory stores a number of BIOS data of the BIOS program, and each BIOS data corresponds to a default BIOS address and is allocated in a flash memory type BIOS address.

After the PCI slave interprets the BIOS access instruction, the address converter converts the default target address into a flash memory type target address, which is one of the flash memory type BIOS address. The flash memory controller accesses the BIOS data allocated at the flash memory type target address accordingly.

Abstract: In some embodiments, the invention involves speeding boot up of a platform by initializing the video card early on in the boot process. In an embodiment, processor cache memory is to be used as cache as RAM (CAR). Video graphics adapter (VGA) card initialization uses the CAR instead of system RAM to perform initialization. A portion of the firmware code, interrupt vector tables and handlers are mirrored in the CAR, from flash memory to mimic the behavior of system RAM during the video initialization. VGA initialization may occur before system RAM has initialized to enable early visual feedback to a user. Other embodiments are described and claimed.
