QUALIFICATIONS
Since 1977, when I first started working with the 8080, until today, working with Pentium class processors in protected mode, I have closely followed and worked in the leading edge of technology. I have covered a wide range of software engineering fields, from digital signal processing, through simulation and systems control, up to Management Information Systems. My background in Hardware Engineering and Microprocessors has given me an advantage and allowed me to succeed in hardware related programming, finally focusing on Real-Time and Firmware systems engineering.
Understanding the need not only for good engineering, but for efficient design and successful products as well, I moved on to total system responsibility and closer contacts with clients. That experience has enabled me to foresee possible problems in the course of a project, provide accurate estimates and design highly successful systems.
Participated and followed many projects closely as they went through concept, specification, budgeting, management approval, design, development, prototyping, testing, integration and production phases. The involvement in so many projects and areas gave me the rare opportunity to observe and learn about successful design and development methods.
Composed a large variety of project related documents: product specifications, cost analysis and breakdowns, architecture designs, software designs, performance analysis, test plans, verification procedures and more.
REAL-TIME SOFTWARE
During my career, I have specified, designed, written, debugged, integrated, tested and documented complex Real-Time systems. These systems were connected to a variety of external devices such as switchboards, RF equipment, voice response equipment, special disk drives, fax modems, Ethernet networks, manufacturing robots, RADARs, mainframes, medical equipment, et al. During the development of these products, I had to not only implement deep knowledge and experience in Real-Time principles and algorithms, but also to study and understand the other unrelated devices interacting with the main processor, as well as the hardware components of the system itself. A condensed overview of these projects is:
Designed, performed and analyzed software performance tests of Real-Time systems. Among the various tests were overall system performance tests, worst cases predictions, worst, average and best cases idle time and degradation analysis.
Created a multi-function switchboard control system based on a single CPU computer. The system replaced a multi-CPU design and saved hardware expansions, inter-machine connections and software maintenance.
Improved Real-Time systems efficiency and saved expensive processor upgrade.
Investigated problems in a manufacturing-floor control system and recommended changes and improvements.
Converted an existing Relational Database system to a Real-Time based computer.
Configured, implemented and tested communication extensions to a Real-Time kernel.
FIRMWARE
Software engineering by itself is not enough for successful firmware systems. The designer, and, ideally, the implementer, must know and understand the uniqueness of a stand-alone embedded system and the surrounding hardware devices. Many times we find highly limiting constraints such as memory shortage or limited hardware support and must deal with them to the best of our knowledge and experience. I have experienced many types of problems - and found solutions - as I worked on and headed up many firmware projects. A few of these projects were:
Integrated a smoke detector device into an existing fire alarm system.
Developed and integrated a DSP based DTMF receiver controller board. Although the project was managed under serious time constraints, it was delivered on time, to the customer's full satisfaction.
Designed, developed, integrated and tested downloadable firmware for a fax modem board. During the development process, I used a variety of software and hardware tools such as compilers, linkers, debuggers, in-circuit emulators, logic analyzers, scopes, et al.
Managed maintenance of boot, configuration and diagnostics firmware for a large Real-Time system. This process involved coordinating between several teams and departments, understanding the needs of the application programmers and quick response time.
Completed bootstrap loader for an embedded system.
Designed and built hardware upgrades to existing boards.
Completed a weighing system project, both hardware and software.
Participated in a large missile control project. In that project, we faced severe memory shortage and growing demands from the customers: easy-to-use human interface, advanced digital filtering algorithms and many input/output devices. The ability to condense all the necessary functionality into the limited number of EPROMs was a great success.
DEVICE DRIVERS
When we design a device driver, a wide variety of disciplines must be taken into account: from operating systems concepts and structure, through the architecture of the computer to deep knowledge of the hardware device being connected. In addition, device drivers are very difficult to debug and cannot tolerate internal malfunctions. The result is that designing and writing device drivers is, probably, one of the greater challenges in software engineering. I have experience in designing, building and debugging device drivers, and those projects include:
Designed, wrote and integrated a disk device driver for a Real-Time operating system. The device driver implemented disk mirroring, and had to be transparent to the application. The use of the new device driver not only added to the system reliability, but also increased the overall system performance.
Rewrote and integrated serial and parallel port device drivers for a Real-Time operating system.
Designed and wrote an intelligent serial ports board device driver. The use of an external processor based board helped offload the main processor utilization.
Designed and managed a fax board device driver project.
Designed and wrote a 9-track tape device driver for a UNIX operating system.
Designed and wrote a device driver for an 8" diskette.
NON-HARDWARE RELATED SYSTEMS
Many times we find that knowledge and experience in Real-Time systems, Firmware and Device Drivers is not enough, and a noticeable portion of a project is devoted to "regular" software engineering such as building test systems, special development tools, interfaces to databases and human interfaces. Throughout my career I have participated and completed many non-hardware related projects, as the following partial list will show:
Wrote and integrated a Smart Card system.
Implemented an improved help system in Windows-based applications.
Designed and wrote PC based prototypes of microcontroller based systems.
Designed, wrote, integrated and tested a voice response machine.
Designed and implemented a database system for medical equipment.
Installed and maintained a 40 station LAN.
Implemented mathematical algorithms for a medical instrument.
Developed an Image Processing system.
System and application programmer for a data processing company.
Developed an assembler, linker, simulator and debugger for a Real-Time project.
Implemented an improved help system in Windows-based applications.
