關于FPGA流水線設計的論文
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.
describes the most common terms used in radarsystems, such as range, range resolution, Doppler frequency, and coherency.
The second part of this chapter develops the radar range equation in many of its forms. This presentation includes the low PRF, high PRF,search, bistatic radar, and radar equation with jamming.

All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.)
The goal of this project is to explore the idea of point-based
radiosity, which is a shooting radiosity technique suggested by Mark
Harris at UNC. The primary idea is that features available in
graphics hardware can be utilized to perform radiosity calculations.
Facilities such as flat shading, diffuse lighting, projective
textures, and mipmapping can be used to replace traditional numerical
solutions for radiosity.
