Fast and transparent file system and SWAP encryption package for linux. No source code changes to linux kernel. Works with 2.6, 2.4, 2.2 and 2.0 kernels.
An Efficient and Effective Detailed Placement Algorithm
Global SWAP
To identify a pair of cells that can be SWAPped to reduce wirelength (others are fixed).
2. Vertical SWAP
SWAP a cell with a nearby cell in the segment above or below.
3. Local Re-ordering
Re-order consecutive cells locally to reduce wirelength.
4. Single-Segment Clustering
Place cells optimally within a segment.
The LTC®4223 is a dual Hot SWAP™ controller that meetsthe power requirements of the Micro TelecommunicationComputing Architecture (MicroTCA) specifi cation recentlyratifi ed by the PCI Industrial Computer ManufacturersGroup (PICMG).
Many system designers need an easy way to producea negative 3.3V power supply. In systems that alreadyhave a transformer, one option is to SWAP out the existingtransformer with one that has an additional secondarywinding. The problem with this solution is that manysystems now use transformers that are standard, offthe-shelf components, and most designers want toavoid replacing a standard, qualifi ed transformer with acustom version. An easier alternative is to produce thelow negative voltage rail by stepping down an existingnegative rail. For example, if the system already employsan off-the-shelf transformer with two secondary windingsto produce ±12V, and a –3.3V rail is needed, a negativebuck converter can produce the –3.3V output from the–12V rail.
