Six Five Oh Two

I-SixFiveOhTwo iyi-emulator ephelele ye-WDC W65C02S CPU esebenza ngqo kudivayisi yakho ye-Android. Bhala ikhodi yokuhlanganisa engu-6502, uyihlanganise ibe yi-bytecode ngesikhathi sangempela, bese ubuka i-CPU iyisebenzisa — konke kusuka ephaketheni lakho.

Ukulingisa Okugcwele kwe-CPU
Kufakiwe yonke imiyalelo eyisisekelo engu-56, izindlela zokuthumela amakheli ezingu-15, ama-opcode angu-242 asebenzayo, izibalo ze-BCD, ukuphazamiseka kwehadiwe (IRQ, NMI, BRK), kanye nazo zonke izikhonkwane ze-CPU ezingu-40 (PHI2, RESB, NMIB, IRQB, ibhasi lekheli, ibhasi ledatha, nokuningi). Isikhala sekheli esingu-64 KB sihlanganisa ikhasi elingu-zero, i-hardware stack, i-RAM ejwayelekile, isibonisi sombhalo esingu-40×25 ku-$0400, kanye namavekhtha ajwayelekile e-NMI/Reset/IRQ.

Umhleli We-Native Assembly
Bhala futhi uhlele i-6502 assembly ngqo kumhleli we-native ophucuziwe ngokugqamisa kwe-syntax yesikhathi sangempela - ama-mnemonics, amalebula, iziqondiso, amarejista, izinombolo, kanye namazwana konke kufakwe amakhodi emibala. Londoloza izinhlelo zakho ngamagama, uzilayishe kabusha noma nini, bese uzisusa uma usuqedile.

Izinhlelo Zezibonelo Ezakhelwe Ngaphakathi
Qala phansi ngezinhlelo zezibonelo ezihlanganisa imiyalelo eminingi, izindlela zokuthumela amakheli, kanye namaphethini wokuhlela avamile: izibali, imisebenzi yememori, ukudluliselwa kwerejista, izinqubo ezincane, ikheli elingaqondile, ukuhlolwa kwefulegi/igatsha, izibalo eziningi, ukuphathwa kwe-bit, ukuhlunga ama-algorithms, ukuphathwa kokuphazamiseka, ukuboniswa kombhalo, i-BCD, nokuningi.

Amadokhumenti Okubhekisela Kuhlelo Lokusebenza
Ungalokothi ushiye uhlelo lokusebenza ukuze ubheke okuthile. Idrowa lokuzulazula linikeza ukufinyelela okusheshayo ku-Assembly Language Quick Reference ephelele kanye ne-Opcode Table ephelele - kokubili kuyatholakala njenge-overlays ngaphandle kokuphazamisa iseshini yakho ye-emulator.

Isitoreji Esiqhubekayo
Zonke izinhlelo zakho - isibonelo kanye nokubhalwa ngumsebenzisi - zigcinwa kudathabheyisi yendawo. Umsebenzi wakho uhlala ukhona lapho ubuya.

I-UI Ehlanzekile Yamathebhu
I-interface yamathebhu ye-emulator ikuvumela ukuthi uhlole amarejista e-CPU, okuqukethwe kwememori, izimo zephini ngazinye, kanye nokukhishwa kokubonisa umbhalo, konke kusakhiwo esihlanzekile esilungiselelwe izikrini zeselula.

Isekela izandiso ze-W65C02S: i-BRA, i-PHX, i-PLX, i-PHY, i-PLY, i-STZ, i-TSB, i-TRB, i-WAI, i-STP, i-RMB0–7, i-SMB0–7, i-BBR0–7, i-BBS0–7.

Kungakhathaliseki ukuthi ufunda ukuhlanganiswa kwe-6502, uphinda ubuyekeze i-retro computing yakudala, noma uhlola izinhlelo ezisezingeni eliphansi usohambeni, i-SixFiveOhTwo ibeka indawo ephelele yokuthuthukiswa nokusebenza ezandleni zakho.
