That Blue Square Thing

AQA Computer Science GCSE

July 2019: the AQA CompSci area is almost complete. Most of the content for units 3-6 is now up and there's quite a lot of Unit 7 material. There's still some work to do, particularly on Paper 1 units, but it's getting there.

Computer Systems - Embedded Systems

Embedded systems are the computers that run everything from our washing machines to our cars. You need to know what they are, how they differ from general purpose computers and, very basically, how they are programmed.

Syllabus content:
PDF iconUnit 2 content - PDF doc to download and print
Note: this syllabus content is a slightly amended version of the one published freely on the web by AQA. I have made very minor adjustments to remove some content less suitable for students to use and it is presented here simply to allow the children I teach to download a usable copy of the syllabus content. It is copyright AQA and reproduced here simply to make access easier for students. No attempt to claim copyright is being made, although I could have copied the text into my own interpretation...

I mentioned assembly code on the Fetch-Execute Cycle page. It's a low level programming language that can be used to program embedded systems directly.

The content here is partly from Unit 2 - which is tested on Paper 1 - but is also mentioned in Unit 4, particularly in relation to embedded systems.

You also need to know the difference between an assembler, an interpreter and a compiler and the benefits and problems of using each.
