Whakaahuatanga
Ko te Arm Cortex-M4 pūtukatuka me te FPU te reanga hou o nga pūtukatuka Arm mo nga punaha whakauru.Kua whakawhanakehia hei whakarato i tetahi papaa utu iti e tutuki ana i nga hiahia o te whakatinanatanga o te MCU, me te iti o te tatau titi me te iti o te kohi hiko, i te wa e whakaputa ana i nga mahi rorohiko tino pai me te whakautu whakamua ki te aukati.Ko te Arm 32-bit Cortex-M4 RISC pūtukatuka me te FPU e whakaatu ana i te tino pai-waehere, e tuku ana i nga mahi teitei e tumanakohia ana mai i te matua Arm, me nga rahi mahara e hono ana ki nga taputapu 8- me te 16-bit.Ka tautokohia e te tukatuka he huinga o nga tohutohu DSP e taea ai te tukatuka tohu pai me te mahinga algorithm matatini.Ko tana FPU tika kotahi ka tere ake te whanaketanga rorohiko ma te whakamahi i nga taputapu whanaketanga reo, me te karo i te waatea.Me tana matua Arm kua mau, he hototahi te whanau STM32F334x4/6/8 ki nga taputapu Arm katoa me nga rorohiko.
