tailieunhanh - Patterns For Time Triggered Embedded Systems

The chapters in this introductory section are intended to answer the following questions: What is an embedded system? What is a time-triggered system and what are the alternatives? Why are time-triggered systems generally considered to be more reliable than systems based on different architectures? What is a software pattern? How can patterns assist in the creation of reliable embedded applications | Patterns for Time Triggered Embedded Systems Michael J Pont Building reliable applications with the 8051 family of microcontrollers Foreword by Kent Beck TTE RapidiTTy FPGA RapidiTTy FPGA includes the full source-code for the PH 03 Core which is a full 32-bit processor core based on the MIPS I Instruction Set Architecture excluding patented instructions . It includes the following peripherals JTAG Debugging. 16-bit Timer. Buffered UART. These peripherals are connected to the processor core through the use of a dedicated bus which can be used to expand the functionality of the PH Core. RapidiTTy Builder RapidiTTy Builder ships with library code covering many common embedded tasks including reading from switches interfacing with LCDs receiving input from ADCs RS-232 communications PWM output and many more. The TTE Builder engine enables this library code to be combined and configured to match the needs of a specific application. For example we may wish to acquire an analogue signal process it in some way and then output the result. This is easily accomplished Select and configure the ADC library. Select and configure the PWM library. Write a few simple lines of code to interface them. At this point we have a complete application that we have created from scratch in minutes. It is also easy to extend as most of the required code has already been generated by RapidiTTy Builder.
