所有学习MSP430的筒子们都应该精读的内容 [复制链接]

其实这个内容不是别的就是TI ULP的规则
http://processors.wiki.ti.com/index.php/ULP_Advisor?DCMP=MSP430&HQS=Other+OT+ulpadvisor
这些规则应该是半导体的设计方通过MCU的运行方式，代码的编译方式以及各种实际的运行环境总结出来的一套规则。
大家如果看到任何不理解的地方，可以到板块发帖讨论。


ULP Advisor - Rule Table

ULP 1.1 Ensure LPM usage
ULP 2.1 Leverage timer module for delay loops
ULP 3.1 Use ISRs instead of flag polling
ULP 4.1 Terminate unused GPIOs
ULP 5.1 Avoid processing-intensive operations: modulo, divide.
ULP 5.2 Avoid processing-intensive operations: floating point
ULP 5.3 Avoid processing-intensive operations: (s)printf()
ULP 6.1 Avoid multiplication on devices without hardware multiplier
ULP 6.2 Use MATHLIB for complex math operations
ULP 7.1 Use local instead of global variables where possible
ULP 8.1 Use 'static' & 'const' modifiers for local variables
ULP 9.1 Use pass by reference for large variables
ULP 10.1 Minimize function calls from within ISRs
ULP 11.1 Use lower bits for loop program control flow
ULP 11.2 Use lower bits for port bit-banging
ULP 12.1 Use DMA for large memcpy() calls
ULP 12.1b Use DMA for potentially large memcpy() calls
ULP 12.2 Use DMA for repetitive transfer
ULP 13.1 Count down in loops
ULP 14.1 Use unsigned variables for indexing
ULP 15.1 Use bit-masks instead of bit-fields
