Intel 8085

Abstract: As an instance for a large specification, an algebraic specification of the intel 8085 micro-processor is given. The specification is based on the concepts of hierarchical abstract types and conditional equations. With the help of the specification interpreter RAP, the specification is validated against some of its informal requirements. In the design of large software systems, a number of informal specification properties have to be considered such as style, readability, and structuredness of a specification. These properties are talked about using a couple of small examples.

Abstract: A very small, flexible, high-quality, full-duplex 2.4-kbit/s linear predictive vocoder has been implemented with commercially available integrated circuits. This fully digital realization is based on a distributed signal processing architecture employing three Nippon Electric Company (NEC) µPD7720 signal processing interface (SPI) single-chip microcomputers. One SPI implements the LPC analyzer, a second implements the Gold pitch and voicing decision algorithm, white the third µPD7720 implements the excitation generator and synthesizer. An Intel 8085-based 8-bit microcomputer is used for data transfer, control and multiplexing functions, and communications with the host terminal. The LPC chip set achieves high flexibility by accepting run time initialization options from the Intel 8085. These parameters include choice of linear predictive model (<= 15), analysis and synthesis frame size, and speech sampling frequency, as well as choice of speech input and output coding formats (linear or µ-255 law) and choice of analog or digjtal pre- and deemphasis. A total of 16 integrated circuits is used in the LPC vocoder with a power disipation of 5.5 W and occupying 18 in/sup 2/ of circuit area.

Abstract: A new radiation hardened three micron CMOS process has been developed. It uses a guardbanded P-well with single level polysilicon and single level metal. Plasma processing is used for etching the critical dimension levels of polysilicon, contact window and metal. To date, fifteen designs have been fabricated using the technology. These include CMOS equivalents of the Intel 8085 8-bit microprocessor family, two custom encryption chips of about 19,000 transistors each and custom logic designs using Sandia's standard cell family. Performance of the devices has exceeded all specifications.
