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 6.3 Use Low Energy Accelerator (LEA) software
library
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
