A fractal is generally "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,"[1] a property called self-similarity. The term was coined by Benoî t Mandelbrot in 1975 and was derived from the Latin fractus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion.[2]
The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Specification Revision 2.0a ([Ref 6]) dictates that when a target signals adata transfer, "the target must do so within 16 clocks of the assertion of FRAME#." PCItermination transactions, such as split Response/Complete, are commonly used to meet thelatency specifications. This method adds complexity to the design, as well as additional systemlatency. Another solution is to increase the ratio of the memory frequency to the PCI-X busfrequency. However, this solution increases the required power and clock resource usage.
The LM158 series consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.

- Flag driver threads with PF_FREEZE to support software suspend.
2.0.11 (May 7th, 2004)
- Avoid split-completion bugs in certain PCI-X chipsets by
breaking up large completion entry DMAs on ADB boundaries.
2.0.10 (April 9th, 2004)
- Return "command timeout" status instead of "selection timeout
status" to the SCSI mid-layer in response to selection timeouts.
While the latter may seem more correct, the mid-layer will not
offline devices suffering from persistent selection timeouts.
This leads to extremely long recovery times for devices that
go missing. Returning command timeout status causes the mid-layer
to enter recovery and eventually offline persistently missing
devices.
The SST89E516RDx and SST89V516RDx are members
of the FlashFlex51 family of 8-bit microcontroller products
designed and manufactured with SST’s patented and proprietary
SuperFlash CMOS semiconductor process technology.
The split-gate cell design and thick-oxide tunneling
injector offer significant cost and reliability benefits for SST’s
customers. The devices use the 8051 instruction set and
are pin-for-pin compatible with standard 8051 microcontroller
devices.
