8位單片機(jī)很多地方需要隨機(jī)數(shù),比如游戲的洗牌,可在timer中取數(shù),但是隨機(jī)數(shù)質(zhì) 量不高。隨機(jī)數(shù)是一個(gè)既簡(jiǎn)單又復(fù)雜的問題,這里的例子使用了眾所周知的線性疊加法,沒 有完美的方法產(chǎn)生隨機(jī)數(shù),不過線性疊加法是一個(gè)合適的方法,徹底解決8位機(jī)隨機(jī)數(shù)的問 題。

UCOS/II for ICCAVR - The version of UCOS/II is 2.04 - the original port was done by Ole Saether for the IAR compiler. Jens E. Holtegaard ported one version using ICCAVR. Joerg Meyer did another port (using Jens port as a start?). This is basically Joerg s port plus a little bit of changes and documentation by me. - YOU MUST DOWNLOAD THE MAIN PART OF THE UCOS/II FROM THE UCOS/II WEBSITE http://www.ucos-ii.com . The supplied project file assumes the portable source is in the ..\source directory. - Joerg has written couple document showing the stack frames etc. but it is in German :-) They are included in this directory. - The Timer2 overflow interrupt is used for Timer Tick. If you want to change that, modify os_cpu_c.c and os_cpu_a.s - I have tested this using ATMega103 with and without external RAM using AVR Studio simulator. See test1.c test program. Both Code Compressed (PRO) and STD versions have been tested.

Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.
