    Programmable Digital Microcircuits - a Survey with Examples of Use

    - 237 - PROGRAMMABLE DIGITAL MICROCIRCUITS - A SURVEY WITH EXAMPLES OF USE C. Verkerk CERN, Geneva, Switzerland 1. Introduction For most readers the title of these lecture notes will evoke microprocessors. The fixed instruction set microprocessors are however not the only programmable digital mi• crocircuits and, although a number of pages will be dedicated to them, the aim of these notes is also to draw attention to other useful microcircuits. A complete survey of programmable circuits would fill several books and a selection had therefore to be made. The choice has rather been to treat a variety of devices than to give an in- depth treatment of a particular circuit. The selected devices have all found useful ap• plications in high-energy physics, or hold promise for future use. The microprocessor is very young : just over eleven years. An advertisement, an• nouncing a new era of integrated electronics, and which appeared in the November 15, 1971 issue of Electronics News, is generally considered its birth-certificate. The adver• tisement was for the Intel 4004 and its three support chips. The history leading to this announcement merits to be recalled. Intel, then a very young company, was working on the design of a chip-set for a high-performance calculator, for and in collaboration with a Japanese firm, Busicom. One of the Intel engineers found the Busicom design of 9 different chips too complicated and tried to find a more general and programmable solu• tion. His design, the 4004 microprocessor, was finally adapted by Busicom, and after further négociation, Intel acquired marketing rights for its new invention.

To achieve this goal, analytical review of modern scientific-and-technical, normative, technical, and medical literature involving scientific and technical problems has been performed; the research area has been chosen and justified, including the definition of optimal electrodes and their affixing to the body of the patient, the definition of the best suitable power source and its operation mode, the definition of the best suitable useful signal amplifiers, and a system of filtering off external noises. A neuro-device mock-up has been made for recognizing electrophysiological signals and transmitting them to the exoskeleton, also the software has been written.

    How to Make Ez80 Code Execute Faster with Copy To

    Application Note How to Make eZ80® Code Execute Faster with Copy To RAM AN015103-1208 Abstract Two popular versions of the eZ80 offered by Zilog® are the eZ80 General-Purpose MPU This Application Note discusses how Zilog’s (eZ80L92) and the eZ80Acclaim! Family of Flash eZ80® code can execute faster by executing from MCUs, which includes the eZ80F91, eZ80F92, and RAM instead of Flash Memory, and be able to eZ80F93 devices. store the eZ80 code in Flash. With Zilog Develop- ment Studio II (ZDS II) code development tools, a eZ80L92 Features few simple changes to the project settings and the project link file are required for speedy code exe- The key features of eZ80L92 include: cution.
