關(guān)于FPGA流水線設(shè)計(jì)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.

This set of simulation files performs a computational complexity performance comparison of the two methods mentioned in the paper. The source is ANSI-C compliant, hence any C-compiler can be used to compile the source code. It has been tested using Visual Studio.net C++ and TI code composer studio C compiler for the TMS320C6701. Note that the performance comparison may be different for different platforms.

PCI-to-PCI Bridge Architecture Specification Revision 1.1 This specification establishes the requirements that a PCI-to-PCI bridge must meet to be compliant to this specification and the PCI Local Bus Specification. In addition, the requirements for optional extensions are specified. This specification does not describe the implementation details of any particular requirement or optional feature of a PCI-to-PCI bridge, nor is it a goal of this specification to describe any particular PCI-to-PCI bridge implementation. However, some recommendations are provided for some implementation-specific features that can be provided by a PCI-to-PCI bridge.

The source code for this package is located in src/gov/nist/sip/proxy. The proxy is a pure JAIN-SIP application: it does not need proprietary nist-sip classes in addition of those defined in JAIN-SIP 1.1, you can substitute the NIST-SIP stack by another JAIN-SIP-1.1 compliant stack and it should interoperate. he proxy can act as presence server and be able to process NOTIFY and SUBSCRIBE requests. If this parameter is disabled, the proxy will simply forward those kind of requests following the appropriate routing decision.

This is the library for all storage drivers. It simplifies writing a storage driver by implementing 90 percent of the code required to support Plug and Play, Power Management, et cetera. This library is used by disk.sys, cdrom.sys and the tape class drivers. No INF file is needed to install this library. The library is 64-bit compliant.

The Tremor Vorbis I stream and file decoder provides an embeddable, integer-only library [libvorbisidec] intended for decoding all current and future Vorbis I compliant streams. The Tremor libvorbisidec library exposes an API intended to be as similar as possible to the familiar vorbisfile library included with the open source Vorbis reference libraries distributed for free by Xiph.org. Tremor can be used along with any ANSI compliant stdio implementation for file/stream access, or use custom stream i/o routines provided by the embedded environment. Both uses are described in detail in this documentation.
