I need advice on the suitability of it as a final year engineering project, is it worthwhile? is it too simple? The only people qualified to answer that are the appropriate staff at your college! Nobody else knows what the specific requirements of your course may be! I know that the MCS-51 family is not particularly suited for math operations. In fact, it is not at all suited to them! So why did you choose it? 1) Implementation on a simple 8-bit microcontroller like 8051 or pic 16x to bring down cost. Have you actually looked at the cost of low-end Cortex-M3 (ARM) microcontrollers? 2) Minimal code size and acceptable speed(order of ms as the user is not too fast) despite being run on the above. Precisely because the 8051 is not well suited to this, it may well take more code than a better-suited processor! Take a look at the comparisons here: http://www.keil.com/support/m...access.htm and here: http://www.keil.com/support/m...access.htm In the first, the 8051 is well-suited - and wins hands-down with only 25% the code size of the ARM; In the second, the 8051 is ill-suited - and loses hands-down with the ARM requiring only 25% the code size of the 8051! 6) Most importantly, a calculator that's cheaper, faster and more powerful than the 'role-model' fx-991 No chance - not with an ARM, not with an 8051. Casio achieve their price with a fully-custom chip and huge volumes. |
