Which phones have this memory architecture vs. dma?
- Tepix 12y agoI know no recent LTE baseband phones that have this isolation.
- swetland 12y agoGalaxy Nexus did (though that's not particularly recent). I suspect most Tegra-based devices do -- though they introduced a combo apps/model Tegra 4i last year, which likely shares resources. Generally if it has a standalone apps processor that's provided by a different vendor than the modem it probably does. Even with unified apps/modem designs, some newer SoCs are designed to provide isolation between the cores, but from a tinfoil hat perspective that requires you to trust the SoC vendor (and perhaps the fab), so if you're paranoid you'd probably avoid any combo designs.
