Free pascal compiler for 8051 microcontrollers

If you like to work with 8051 microcontrollers and like Pascal programming language, here is Turbo51 – a free Pascal compiler for the 8051 families of microcontrollers. In the 1980s, Intel introduced the 8051 as the first member of the MCS-51 family of microcontrollers. Today hundreds of cheap 8051 derivatives are available from tens of manufacturers. This makes the MCS-51 architecture so interesting for professionals and hobbyists. It is a somewhat surprising fact that this 8-bit architecture is still in use today. In other words, it is still trendy. Several C compilers are available for the 8051. However, there are only a few Pascal compilers for the 8051 families available. There are many debates on which programming language is better. Turbo51 is for those who prefer Pascal. Turbo51 features a fast single pass optimizing compiler, Borland Turbo Pascal 7 syntax, full floating point support, mixed Pascal and assembler programming, full use of register banks, advanced multi-pass optimizer, smart linker, generates compact high-quality code, output formats include binary, Intel HEX and assembler source.

Automated electronic CAD systems overview

More and more design operations become automated. These changes give many benefits like effectiveness, minimal errors, and less routine operations to designers. Modern electronic equipment requires scrupulous planning as devices shrink to minimal sizes, operation power increases, and it fit its external design requirement. So designing is a very complex task where without smart CAD software would be almost impossible to do. When designing a new electronic device, you have to deal with several necessary areas to make the device a reliable and attractive device. All of these areas usually are done on a particular CAD system. The most common CAD-based electronic specific task are: Mixed Analog-digital device modeling; Programmable Logic modeling and synthesis; HF circuits and electromagnetic modeling; Functional modeling; PCB Design; Thermal modeling; Chip topology modeling. Each of these modeling and designing processes requires different skills and knowledge. Let’s go through each to see their specifics and what CAD systems are used to automate related tasks.
