Instruction set of LPC5526

[_Ferrari_]

Dear all,

I am designing an application based on the LPC5526 processor where execution speed is very important.
I would like to know how many clock cycles are required to perform an integer multiplication.

According to the official ARM documentation, the Cortex M33 core should use a single clock cycle to perform an integer multiplication. Can you confirm this?

regards

Hello @_Ferrari_ ,

On the LPC55S2x/LPC552x, the Cortex-M33 is used. Please refer to Cortex-M33 – Arm® documentation to get the integer multiplication speed (clock cycles). In Cortex-M33 Devices Generic User Guide you could find the Instruction Set of the Cortex-M33.

Best regards, Raul.
