Hello people. I'm trying to do libgcc extraction for hard FPU's for k70 tower board. However, when I look at the libgcc library for arm targets, I find armv7-m, armv7e-m and armv7e-m-pic. I'm able to deduce from the armv7-m reference manual that the difference between armv7-m and armv7e-m is of the DSP chip i.e. armv7e-m will have a DSP chip. As the k70 has a DSP chip, therefore I'm able to conclude that I have the armv7e-m architecture. However, I'm unable to figure out the difference between armv7e-m and armv7e-m-pic? There is no reference about it in the armv7-m reference manual. Can someone help me out here?
Thanks, Bilal
Hello Bilal,
I hope the following link useful to you. And one question I want to answer that is difference between armv7e-m and armv7e-m-pic. Armv7 -M supports mainly thumb instruction set. And coming to "pic" as far I know generally microcontrollers doesn't have a inbuilt function from analog to digital convertors. So we use analog to digital ic's in our boards to get that usage. But PIC is a microcontroller having inbuilt analog to digital convertor so no need to use extra ic's.
