I'm not sure I follow. It's almost guaranteed that all chiplets are still on some global system bus just like they were on their monolithic dies. Unless Intel has taken sudden great strides with their SoC security architecture, there are likely still all the old problems (plus a bunch of new fun ones!). Taking it off die is a response to the physical scaling issue, it's really not meant as a security enhancement.
- transpute 3y agoPer the article, both IP blocks remain within the same SOC chiplet/tile. https://en.wikipedia.org/wiki/Intel_Management_Engine https://en.wikipedia.org/wiki/Intel_Management_Engine > Starting with ME 11, it is based on the Intel Quark x86-based 32-bit CPU and runs the MINIX 3 operating system. If "Silicon Security" functions are now executing on a separate CPU/OS, it's an increase in separation from Intel ME functions. https://www.anandtech.com/show/20046/intel-unveils-meteor-lake-architecture-intel-4-heralds-the-disaggregated-future-of-mobile-cpus/3 https://www.anandtech.com/show/20046/intel-unveils-meteor-la... > [Meteor Lake] introduces the Intel Silicon Security Engine (ISSE), a dedicated component focused solely on securing things at a silicon level ... The Converged Security and Manageability Engine (CSME) has also been partitioned to further enhance platform security.
