In an embedded system, firmware is the software that directly interfaces with the microcontroller, controlling the system’s function. The major forces driving the embedded firmware development process today are reduced development times, increased complexity, and the need to handle multiple tasks simultaneously. These forces translate into strenuous design requirements for embedded engineers and programmers. Many low-level embedded microcontroller designs have insufficient memory and/or architectural limitations that make the use of a real-time operating system impractical. The techniques presented in this book allow the design of robust multitasking firmware through the use of interleaved state machines. This book presents a complete overview of multitasking terminology and basic concepts. Practical criteria for task selection and state machine design are also discussed.Designing multitasking firmware is arduous, complex and fraught with potential for errors, and there is no one, “standard” way to do it. This book will present a complete and well-organized design approach with examples and sample source code that designers can follow. more...

Decisive biotechnological interventions in the lottery of human life--to enhance our bodies and brains and perhaps irreversibly change our genetic makeup--have been widely rejected as unethical and undesirable, and have often met with extreme hostility. But in Enhancing Evolution, leading bioethicist John Harris dismantles objections to genetic engineering, stem-cell research, designer babies, and cloning to make a forthright, sweeping, and rigorous ethical case for using biotechnology to improve human life. Human enhancement, Harris argues, is a good thing--good morally, good for individuals, good as social policy, and good for a genetic heritage that needs serious improvement. Enhancing Evolution defends biotechnological interventions that could allow us to live longer, healthier, and even happier lives by, for example, providing us with immunity from cancer and HIV/AIDS. But the book advocates far more than therapies designed to free us from sickness and disability. Harris champions the possibility of influencing the very course of evolution to give us increased mental and physical powers--from reasoning, concentration, and memory to strength, stamina, and reaction speed. Indeed, he supports enhancing ourselves in almost any way we desire. And it's not only morally defensible to enhance ourselves, Harris says. In some cases, it's morally obligatory. Whether one looks upon biotechnology with hope, fear, or a little of both, Enhancing Evolution makes a case for it that no one can ignore. more...
