Iapha  We will need to compute the Id and Iq.

 Traditional Method for computing Id/Iq  Step 1 – Refer to lookup table for cos  Step 2 – Multiple Ialpha with lookup table value  Step 3 – Refer to lookup table for sin  Step 4 – Multiple Ibeta with lookup table value  Step 5 – Add up both result to obtain Id

Page 28 Infineon MCU Key Features for Motor Drive Vector Computer – CORDIC - Park Transform using CORDIC Use CORDIC  Instruction 1 – Setup the CORDIC mode  Instruction 2 – load Z with angle value  Instruction 3 – load X with Ialpha value  Instruction 4 – load Y with Ibeta value, Cordic start automatically CORDIC will output the result of Id and Iq together

 MDU is very useful for some mathematical functions such as UIDIV, LMUL, ULDIV, LShift  ROM contains most valuable MDU-routines which can be called by user – this saves code space and runtime (no wait-state for ROM access)  Easy integration with KEIL compiler  MDU Library support in ROM only available for devices marked with “M”
