DP839EB-ATS SONIC Packet Driver for PC/TCP by FTP Software DP839EB-ATS SONIC Packet Driver for PC/TCP by FTP Software AN-748 National Semiconductor DP839EB-ATS SONIC Application Note 748 Packet Driver for PC/TCP January 1991 by FTP Software INTRODUCTION This is a program listing for a driver for the DP839EB-ATS This software does not make use of higher performance SONIC Ethernet Adapter. This driver enables the DP839EB- upper level features, and performance is limited by this. ATS to operate with a TCP/IP software package from FTP The driver is listed by modules in the order listed below. Software Inc. called PC/TCP. This driver is written to ver- 1. pktdrv.c 6. sonic.h sion 2.0x of this software package. 2. far.c 7. isrlib.asm This software program listing is provided primarily as a pro- gramming example for writing software for the DP83932 3. isr.c 8. pktint.asm Systems Oriented Network Interface Controller. This driver 4. sonic.c 9. pktdrv.mak (make file) is written in Microsoft C 5.1 and Microsoft Assembler 5.1. 5. pktdrv.h Since the bulk of the software is written in C, the concepts provided are easily portable to other environments. This example driver was not written to achieve optimum per- formance with PC/TCP, but primarily to show how the SON- IC Controller can be programmed.

  • Discrete Semiconductor Products Fairchild@50
    Fairchild Oral History Panel: Discrete Semiconductor Products Fairchild@50 (Panel Session # 3) Participants: Jim Diller Bill Elder Uli Hegel Bill Kirkham Moderated by: George Wells Recorded: October 5, 2007 Mountain View, California CHM Reference number: X4208.2008 © 2007 Computer History Museum Fairchild Semiconductor: Discrete Products George Wells: My name's George Wells. I came to Fairchild in 1969, right in the midst of the Hogan's Heroes, shall we say, subculture, at the time. It was difficult to be in that environment as a bystander, as someone watching a play unfold. It was a difficult time, but we got through that. I came to San Rafael, Wilf asked me to get my ass up to San Rafael and turn it around or shut it down. So I was up in San Rafael for a while, and then I made my way through various different divisions, collecting about 15 of them by the time I was finished. I ended up as executive vice president, working for Wilf, and left the company about a year and a half after the Schlumberger debacle. That's it in a nutshell. Let me just turn over now to Uli Hegel, who was with Fairchild for 38 years, one of the longest serving members, I believe, in the room. Maybe the longest serving member. Uli, why don't you tell us what you did when you came, when you came and what jobs you had when you were there. Uli Hegel: I came to Fairchild in 1959, September 9, and hired into R&D as a forerunner to the preproduction days.

  • The LSI Data Acquisition Peripheral of the Future Coorganizers: John A
    The LSI Data Acquisition Peripheral of the Future Coorganizers: John A. Schoeff - Advanced Micro Devices, Inc., Sunnyvale, CA James Solomon - National Semiconductor Corp., Santa Clara, CA Moderator: Ray Stata, Analog Devices, Inc., Norwood, MA Designers of A/D and D/A converters are beginning to use the same LSI technologies that are available to microprocessor and memory designers, since they offer the potential for large increases in circuit complexity. In exploring the approaches available for tapping this potential, it is also necessary to consider which tech- nologies are most attractive for data acquisition ICs and what are the analog and digital performance limits of these technologies, and within the expected limits, what types of complex data acquisition ICs would be the most interesting to make. In considering the initial problem panelists are expected to weigh the MDS advantage of high digital density against the bipolar advantage of analog precision. It is felt by some that switched-capacitor techniques will allow MOS to equal the analog accuracy of bipolar. For severalyears, wafer level trim (WLT) techniques havebeen pushed as the answer to the monolithic accuracy problem. Progress to dateon WLTwill be reviewed and compared with competing non-trim approaches. Thus, in addressing the fabrication aspect, the panel will review the variety of data acquisition subsystems presently being built at the PC-board level, such as the traditional A/D, reference, mux, S/H amplifier and bus interface. The feasibility, desirability and economics of including multiple designs in a single LSI circuit will be considered. An attempt will also be made to explore new avenues for data acquisition LSI.

  • Winter 2021 the National Microelectronics Challenge
    IQT Insights: The National Microelectronics Challenge Growing U.S. concerns about national microelectronics competitiveness and supply chain security have prompted proposals for government action.1 This policy brief explains IQT’s view that innovation is the key to meeting both competitiveness and security challenges. The paper argues that the nation should address impediments to commercial success in the specific microelectronics technologies that matter most for U.S. security and competitiveness. In so doing, government can better align private sector incentives with the national interest. IQT recognizes the value of boosting federal research and development and building U.S.-based chip manufacturing “The nation must facilities. In IQT’s assessment, however, it is equally important to support priority technologies (e.g., tooling, address impediments packaging) with commercialization support. Government to commercial could support the creation of “sandboxes” to help transition federally funded research from lab to market. Additionally, success in specific government could invest in emerging companies where the microelectronics private sector is not funding specific key technologies at a level commensurate with the national interest. This policy technologies that brief, written for the non-expert, provides background and matter most.” analysis (Section I) and recommendations (Section II). IQT is a non-profit strategic investor that helps deliver emerging technologies to multiple U.S. national security agencies. This analysis flows from our role as one of the world’s most prolific investors operating at the intersection of national security, technology trends, and the private sector. Section I. Background and Analysis Microelectronics are small electronic components (e.g., transistors, inductors, diodes, capacitors) or complex systems (e.g., microprocessors, AI accelerators) which have become vital for powering everything from smart phones to the most advanced military systems.

  • Texas Instruments to Acquire National Semiconductor
    Texas Instruments to Acquire National Semiconductor Combining Linear Strengths Texas Instruments (TI) and National Semiconductor announced April 4, 2011 that the companies have signed a definitive agreement, approved by both companies' boards, under which TI will acquire National for $25 per share in an all-cash transaction worth roughly $6.5 billion. The transaction, which is expected to close in six to nine months, will be financed using a combination of existing cash balances and debt. National will become a part of TI's analog segment. Sales of linear semiconductors (a category that includes analog and other linear functions) will represent almost 50 percent of TI's revenue. In 2010 TI claims to have had a 14% share of the market for linear semiconductors, and put National’s share at 3%. National's headquarters will remain in Santa Clara, California, and TI will continue to operate National's manufacturing plants in Maine, Scotland and Malaysia. Some History It would be a mistake to overlook the histories of these two companies. Both TI and National are some of the oldest manufacturers of semiconductors. Texas Instruments was formed in 1947 to manufacture transistors when those devices were new. National began operations in 1959 in Danbury, Connecticut. Texas Instruments has traveled a long and winding path centering first around its original transistor business and later focusing on the IC, which was first invented at TI in 1958. A strong military leaning during the Cold War led to the company putting a large effort into supporting the military business balanced by computer chips and various thrusts into consumer electronics.

Semiconductor manu- facturers met stiff competition within the industry, particularly from foreign manufacturers. A group of leaders of the industry believed some of their competitors were competing unfairly by stealing product designs.
