This application note provides a detailed description of the Spartan™-3 configurationarchitecture. It explains the composition of the bitstream file and how this bitstream isinterpreted by the configuration logic to program the part. Additionally, a methodology ispresented that will guide the user through the readback process. This information can be usedfor partial reconfiguration or partial readback.

The Virtex™-4 user access register (USR_ACCESS_VIRTEX4) is a 32-bit register thatprovides direct access to bitstream data by the FPGA fabric. It is useful for loadingPowerPC™ 405 (PPC405) processor caches and/or other data into the FPGA after the FPGAhas been configured, thus achieving partial reconfiguration. The USR_ACCESS_VIRTEX4register is programmed through the bitstream with a command that writes a series of 32-bitwords.

多遠(yuǎn)程二極管溫度傳感器-Design Considerations for pc thermal management Multiple RDTS (remote diode temperature sensing) provides the most accurate method of sensing an IC’s junction temperature. It overcomes thermal gradient and placement issues encountered when trying to place external sensors. PCB component count decreases when using a device that provides multiple inputs.Better temperature sensing improves product performance and reliability. Disk drive data integrity suffers at elevated temperatures. IBM published an article stating that a 5°C rise in operating temperature causes a 15% increase in the drive’s failure rate. The overall performance of a system can be improved by providing a more accurate temperature measurement of the most critical devices allowing them to run just a few degrees hotter.The LM83 directly senses its own temperature and the temperature of three external PN junctions. One is dedicated to the CPU of choice, the other two go to other parts of your system that need thermal monitoring such as the disk drive or graphics chip. The SMBus-compatible LM83 supports SMBus timeout and logic levels. The LM83 has two interrupt outputs; one for user-programmable limits and WATCHDOG capability (INT), the other is a Critical Temperature Alarm output (T_CRIT_A) for system power supply shutdown.
