Raspberry Pi-prosjektet har lansert det nye kortet Raspberry Pi Pico 2, som fortsetter utviklingen av de kompakte kortene Pico og Pico W, utstyrt med en mikrokontroller utviklet av dem selv. Kortet produseres p\u00e5 Sony-fabrikken og er tilgjengelig for 5 dollar. Som de tidligere Pico-kortene er den nye modellen hovedsakelig rettet mot sambruk med Raspberry Pi-datamaskiner, utvikling av innebygde systemer og systemer for kontroll av ulike enheter. Innen utgangen av \u00e5ret planlegges det \u00e5 gi ut en modell Pico 2 W med st\u00f8tte for Bluetooth og Wi-Fi (2,4 GHz 802.11n), basert p\u00e5 Infineon CYW43439-brikken. <\/p>\n

Pico 2-kortet er bemerkelsesverdig for sin bruk av den nye mikrokontrolleren RP2350, som sammenlignet med den tidligere benyttede mikrokontrolleren RP2040, inkluderer en mer kraftfull to-kjernes ARM Cortex-M33-prosessor med DSP og en enhet for flyttallsberegning, som opererer p\u00e5 en frekvens av 150 MHz (tidligere ble ARM Cortex-M0+ 133 MHz brukt). I tillegg inneholder den to valgfrie Hazard3-kjerner med RISC-V-instruksjonsarkitektur, som kan byttes om under oppstart for \u00e5 brukes i stedet for ARM Cortex-M33-kjernene. <\/p>\n

Chippet har 520 KB med innebygd RAM (opp fra 264 KB), gj\u00f8r det mulig \u00e5 koble til eksterne QSPI PSRAM-minnemoduler og gir utvidede sikkerhetsmuligheter. Pico 2-kortet leveres med 4 MB QSPI Flash, som er dobbelt s\u00e5 mye som i den forrige modellen. I tillegg er kortet helt kompatibelt med tidligere modeller p\u00e5 niv\u00e5et av maskinvaregrensesnitt og programvare som brukes til applikasjonsutvikling.

\"Raspberry<\/center> <\/p>\n

RP2350-chippen har innebygde maskinvarefunksjoner for \u00e5 beskytte mot angrep ved feilinnspr\u00f8ytning (Fault Injection) og st\u00f8tter Arm TrustZone-teknologi, som kan brukes til \u00e5 verifisere oppstart ved hjelp av digital signatur, gir instruksjoner for \u00e5 akselerere beregningene av SHA-256-hash og p\u00e5litelig generering av tilfeldige tall (TRNG, True Random Number Generator). I tillegg er det 8 KB med engang programmerbar minne, som gir mulighet for \u00e5 skrive data som deretter ikke kan endres eller slettes. <\/p>\n

For application development, programming languages such as C, C++, MicroPython, or CircuitPython can be used. Development in C\/C++ can be done in the Visual Studio Code editor, for which a special extension is available. The chip's capabilities are sufficient for machine learning applications, for which there is a port of the TensorFlow Lite framework. For network access, it is recommended to use the lwIP network stack, which is included in the Pico SDK for developing applications in C, as well as in the MicroPython firmware.
