關(guān)于FPGA流水線設(shè)計的論文
This work investigates the use of very deep pipelines for
implementing circuits in FPGAs, where each pipeline
stage is limited to a single FPGA logic element (LE). The
architecture and VHDL design of a parameterized integer
array multiplier is presented and also an IEEE 754
compliant 32-bit floating-point multiplier. We show how to
write VHDL cells that implement such approach, and how
the array multiplier architecture was adapted. Synthesis
and simulation were performed for Altera Apex20KE
devices, although the VHDL code should be portable to
other devices. For this family, a 16 bit integer multiplier
achieves a frequency of 266MHz, while the floating point
unit reaches 235MHz, performing 235 MFLOPS in an
FPGA. Additional cells are inserted to synchronize data,
what imposes significant area penalties. This and other
considerations to apply the technique in real designs are
also addressed.
unicap provides an uniform access to video capture devices. Currently you can access v4l, v4l2, IIDC 1394 ( DCAM ) cameras and video to firewire converters with a single API. New devices can be added via a plugin system

A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc
Introduction to the MSN Messenger Activity SDK
--- --- --- --- --- --- --- --- --- --- --- --- --- --
The MSN® Messenger Activity software development kit (SDK) contains technical information about how to develop and test single-user and multiuser applications by using the Activity object model. The SDK also provides detailed information about the MSN development and testing requirements that your Activity must meet, and how to increase the usage of your MSN Messenger Activity application.
The source code samples for chapter 2, 4, 6, and 8 are contained in the
EvenChapters project. Those chapters all reference various aspects of this single project.
The source code for the BullsEye control (chapter 10 example) is in the BullEyeCtl project.
The source samples for the other chapters are provided in the Chapter XX sub-directories.
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.
