Tlhaloso

AM1705 ke ARM microprocessor ea matla a tlase e thehiloeng ho ARM926EJ-S.Sesebelisoa sena se nolofalletsa baetsi ba lisebelisoa tsa pele (OEMs) le baetsi ba meralo ea pele (ODM) ho tlisa kapele lisebelisoa tsa 'maraka tse nang le lits'ebetso tse matla tsa ts'ebetso, li-interfaces tse ruileng tsa basebelisi, le ts'ebetso e phahameng ea processor ka ho feto-fetoha ho hoholo ha tharollo ea processor e kopantsoeng ka botlalo.ARM926EJ-S ke 32-bit RISC processor processor core e etsang 32-bit kapa 16-bit litaelo le ts'ebetso ea data ea 32-, 16-, kapa 8-bit.Mokotla o sebelisa pipelining e le hore likarolo tsohle tsa processor le tsamaiso ea memori li ka sebetsa li sa khaotse.Motheo oa ARM o na le coprocessor 15 (CP15), mojule oa ts'ireletso, le likarolo tsa taolo ea memori ea data le lenaneo (MMUs) tse nang le li-buffers tse shebileng tafoleng.Koko ea ARM e na le 16KB e arohaneng ea litaelo le li-cache tsa data tsa 16-KB.Li-memory block ka bobeli li amana le 4-way associative le virtual index virtual tag (VIVT).Moko oa ARM o boetse o na le 8KB ea RAM (Vector Table) le 64KB ea ROM.Sehlopha sa peripheral se kenyeletsa: 10/100 Mbps Ethernet MAC (EMAC) e nang le boitsebiso ba tsamaiso ea ho kenya / ho tsoa (MDIO) module;tse peli tsa I 2C Bus interfaces;likou tse tharo tsa li-multichannel audio serial (McASPs) tse nang le li-serializer le li-buffers tsa FIFO;li-timers tse peli tsa 64-bit ka kakaretso e 'ngoe le e 'ngoe e ka lokisoa (e le 'ngoe e ka lokisoa joalo ka ntja e lebelang);ho fihlela ho libanka tsa 8 tsa li-pin tsa 16 tsa kakaretso-purpose input/output (GPIO) tse nang le mekhoa ea ho sitisa / liketsahalo tsa liketsahalo, tse ngatafalitsoeng ka lisebelisoa tse ling;likhokahano tse tharo tsa UART (e le 'ngoe e nang le RTS le CTS ka bobeli);li-peripheral tse tharo tse ntlafalitsoeng tsa high-resolution pulse width (eHRPWM);li-peripherals tse tharo tsa 32-bit e ntlafalitsoeng ea ho ts'oaroa (eCAP) tse ka hlophisoang joalo ka li-input tse 3 kapa liphetho tse 3 tsa li-auxiliary pulse wide modulator (APWM);li-peripherals tse peli tse ntlafalitsoeng tsa 32-bit quadrature encoded pulse (eQEP);le li-interfaces tsa 2 tsa ka ntle tsa memori: segokanyimmediamentsi sa memori sa asynchronous le SDRAM (EMIFA) bakeng sa memori e liehang kapa li-peripheral, le segokanyimmediamentsi sa memori sa lebelo le holimo (EMIFB) bakeng sa SDRAM.Ethernet Media Access Controller (EMAC) e fana ka sebopeho se sebetsang pakeng tsa sesebelisoa le marang-rang.EMAC e ts'ehetsa 10Base-T le 100Base-TX, kapa 10 Mbps le 100 Mbps ka mokhoa oa half or full-duplex.Ho feta moo, sebopeho sa MDIO se teng bakeng sa tlhophiso ea PHY.
