YAKSoC芯片设计
Introduction
SystemonChip(SoC)isarevolutionaryconceptinelectronicsthatintegratesallofthecomponentsofacomputeronasinglechip.SoCtechnologyhasbecomeakeydriverforthedevelopmentofvariousdevicessuchassmartphones,tablets,wearables,andmanymore.YakSoCisanemergingSoCprocessordesignedspecificallyforlow-powerembeddedapplications.ThispaperdiscussesthedesignofYakSoCanditsbenefits.
YakSoCDesign
ThedesignofYakSoCisbasedontheARMCortex-M3processor.Theprocessorisa32-bitRISC(ReducedInstructionSetComputing)architecturethatprovideshighperformanceandlowpowerconsumption.TheARMCortex-M3processorisusedwidelyinembeddedapplicationsduetoitssmallfootprint,lowpowerconsumption,andlow-costdesign.
YakSoCintegratesseveralblocksofIPs(IntellectualProperties)includingasingle-cyclehardwaremultiplieranddivider,on-chipflashmemory,andseveralcommunicationinterfaces.TheSoCalsocontainsaPowerManagementUnit(PMU)thatenablesdynamicpowermanagementtooptimizethepowerconsumptionofthedevice.
Theon-chipflashmemoryinYakSoCisavailableinsizesrangingfrom256KBto1MB.ThememorycanbeprogrammedanderasedinplacewithouttheneedforexternalEEPROMs.ThisfeaturemakesYakSoCidealforlow-powerapplicationsthatrequireon-chipnon-volatilememory.
YakSoCsupportsseveralcommunicationinterfacesincludingUART,SPI,I2C,andUSB.Theseinterfacesenablecommunicationwithotherdevicesandprovideconnectivitytotheinternet.TheUSBinterfaceinYakSoCsupportstheUSB2.0specification,whichoffersahigh-speeddatatransferrateofupto480Mbps.
YakSoCisalsoequippedwithaReal-TimeClock(RTC)thatprovidesaccuratetimekeepingandenablesthedevicetooperateinlow-powermodes.TheRTCcanbeprogrammedtogenerateinterruptsatsetintervals,allowingthedevicetowakeupfromsleepmode.
