WS2812B RGB Smart Pixel LED
#12
Uzgred ovaj gore AM64x je brutalan kontroler, mnogo ozbiljan i kompleksan, pogledajte STM32F407 sa početka teme, single-core Cortex-M4F na 180MHz.

Ovaj Sitara SoC ima u sebi izmedju ostalog baš to jedno M4F jezgro ali je rezervisan recimo samo za Safety-features, za nadzor sistema, izolovan memoriski i hardwerski čak sa svojim posebnim napajanjem!

Jezgra za real-time su Cortex-R5F, tehnički nadogradjen M4F, sa 800MHz clock i to u konfiguraciji kao 4x nezavistna jezgra ili 2x2 jezgra u lock-step konfiguraciji za safety-specific potrebe, sa ECC memorijom.

Ima još jedno R5F jezgro koje se bavi samo interaptima i clock/power-managmentom za sva ostala jezgra i periferije!

Tek sam počeo da nabrajam jezgra, tu su još i 2x2 PRU-ICSSG jezgra, tek priča za sebe, uglavnom su u stilu Software Defined Network Adapter, učita im se firmware i mogu da postanu recimo 1Gbit kontroleri za industriske protokole, EtherCat, Sampled Values, TSN, bukvalno svi poznati industriski mrežni protokoliki su podržani kroz firmware koji daju, neki su besplatni neki se plaćaju.
Kada se ne koriste ti protokoli, onda su ta jezgra dostupna za bilo kakvo drugo diskretno sofwersko procesiranje sa I/O pinovima, bukvalno su predvidjeni za diskretan bit-banging svih poznatih protokola!

I tu su Cortex-A53 jezgra koja voze linux i ostale periferije koje mogu da se mapiraju na različita jezgra.

Evo spisak jezgra!
