Inkampani U-Olimex usanda kwethula i-CERBERUS 2100, uguquko lwemfundo yesayensi yekhompyutha. Kuyibhodi lezemfundo lehadiwe elivulekile, elihlelekayo ngolimi lwe-BASIC, elinama-microprocessors angu-8-bit Z80 kanye ne-6502, kanye nesilawuli esincane se-Microchip AVR esisebenza njengesilawuli se-I/O. Yebo, ama-CPU e-Zilog Z80 ne-MOS Technology 6502 anika amandla amanye amakhompyutha abaluleke kakhulu emashumini eminyaka edlule.
I-CERBERUS 2100, okuyinto ine-CPLD eminingi, ihleleka ngokuphelele, kusukela ezingeni eliphansi kakhulu (amasango ngamanye kanye nama-flip-flops) kuya kubatoliki be-BASIC abasebenzisa ama-CPU angu-Z80 no-6502. Ibhodi aliwona umklamo ka-Olimex, kodwa laklanywa uBernardo Kastrup (owaziwa nangokuthi TheByteAttic) , kuyilapho abahumushi be-BASIC babhalwa u-Alexander Sharikhin (6502) no-Dean Belfield (Z80).
El Ikhodi ye-BIOS ibhalwe ngo-C futhi ihlanganiswa ngaphansi kwe-Arduino IDE. Ngaphandle kwamasiginali wevidiyo, i-FAT-CAT yenza yonke imisebenzi ye-I/O, efana nokusebenza kwesistimu yefayela, ukulawula ikhibhodi nokunwetshwa, nokukhipha umsindo, futhi isekela ukudluliselwa kwe-DMA nge-FAT-SPACER.
Wonke amafayela okwenziwa kwebhodi ayatholakala ngenxa kaBernardo Kastrup, kodwa ukukhiqiza ngokwayo kwenziwa yinkampani yaseBulgaria i-Olimex, okwamanje ethengisa ibhodi. I-CERBERUS 2100 ngama-euro angama-219. Amafayela edizayini yezingxenyekazi zekhompuyutha, i-firmware, nemibhalo enemininingwane ingatholakala ku-GitHub kanye newebhusayithi ye-TheByteAttic. Kulabo abakhetha okuqukethwe kwevidiyo, isingeniso semizuzu engama-45 siyatholakala.
CERBERUS 2100 Imininingwane
Ngokuqondene ne Ukucaciswa kobuchwepheshe Kuleli bhodi elihlelekayo, sinokulandelayo:
- Amayunithi okucubungula:
- I-Zilog Z80 8-bit CPU ku-4 noma 8 MHz (umsebenzisi angakhetha imvamisa yewashi)
- I-Western Design Center i-W65C02S 8-bit CPU ku-4 noma i-8 MHz (umsebenzisi angakhetha imvamisa yewashi) *[ngenkathi i-Z80 isakhiqizwa yi-Zilog ngokwayo, esasebenza, i-6502 yakhiwe yi-Western Design, kusukela i-MOS Technology. wanyamalala ]
- I-Microchip 328-bit AVR ATMega8PB 328 MHz “FAT-CAT” MCU (isilawuli esincane se-ATmega16pb)
- Ama-CPLD (ATF1508AS-7AX100):
- I-FAT-SCUNK (Scan CoUNter newashi) kanye ne-FAT-CAVIA (I-ChAracter Video Adapter) yamasekhethi evidiyo axhunywe nge-oscillator engu-25.175 MHz
- I-FAT-SPACER (I-Serial to Parallel ControllER) yokuguqulwa kwesiginali, amawashi, i-serial/parallel ne-oscillator engu-16 MHz
- 64 KB RAM engaphathwa umsebenzisi
- Isitoreji: Isikhala sekhadi le-MicroSD ngesistimu yefayela eyakhelwe ku-BIOS (AVR)
- Okukhipha ividiyo nokusekelwa kwezithombe:
- Ukukhishwa kwevidiyo ye-VGA kuze kufike ekulungisweni okungu-320x240 (empeleni kungu-640x480 px namaphikseli angu-2x2)
- Ngokusekelwe ezinhlamvini ezingu-40x30, ngayinye ingalungiseka kuhlamvu ngalunye
- Imibala efika ku-8 ngesikhathi esisodwa esikrinini
- I-bitmap engachazwa kabusha yomsebenzisi eku-fly yezithombe zamathayili noma ze-mosaic
- Ukulungisa iphutha - 3x izixhumi ze-JTAG
- Ukunwetshwa – 40-pin slot enwetshiwe nge-I/O ejwayelekile nge-FAT-CAT kanye ne-FAT-SPACER
- Abanye:
- Isixhumi se-PS/2 sihambisana nekhibhodi ye-USB
- I-buzzer ehlanganisiwe
- Amandla – 5V nge-USB-C
