Intel yatsegula gwero la firmware ya PSE (Programmable Services Engine) unit, yomwe inayamba kutumiza mu Elkhart Lake processors, monga Atom x6000E, yokonzedwa kuti igwiritsidwe ntchito pazida za Internet of Things. Khodiyo imatsegulidwa pansi pa layisensi ya Apache 2.0.
PSE ndi purosesa yowonjezera ya ARM Cortex-M7 yomwe imagwira ntchito mochepa mphamvu. PSE ikhoza kugwiritsidwa ntchito pochita ntchito ya wolamulira wophatikizidwa, kukonza deta kuchokera ku masensa, kukonza zowongolera zakutali, kuchita ntchito zapaintaneti ndikuchita ntchito zapadera padera.
Poyamba, kernel iyi inkayendetsedwa pogwiritsa ntchito firmware yotsekedwa, yomwe inalepheretsa kukhazikitsidwa kwa tchipisi ndi PSE mumapulojekiti otseguka monga CoreBoot. Makamaka, kusakhutira kudayamba chifukwa chosowa chidziwitso chokhudza kuwongolera kwapang'onopang'ono kwa PSE ndi nkhawa zachitetezo chifukwa cholephera kuwongolera zochita za firmware. Chakumapeto kwa chaka chatha, pulojekiti ya CoreBoot idasindikiza kalata yotseguka kwa Intel ikuyitanitsa kuti pulogalamu ya PSE ikhale yotseguka, ndipo kampaniyo pamapeto pake idamvera zosowa za anthu ammudzi.
PSE firmware repository ilinso ndi mayeso oyambilira a zofunikira kwa omanga ndi zitsanzo zogwiritsa ntchito zomwe zimatha kutsata mbali ya PSE, zida zoyendetsera RTOS Zephyr, firmware ya ECLite ndikukhazikitsa magwiridwe antchito ophatikizidwa, komanso kukhazikitsidwa kwa OOB (Out-of-- Band) mawonekedwe owongolera, ndi chimango cha chitukuko cha ntchito.
