WebIn Arm Cortex-M7 based architecture, the memory system includes support for the TCM. The TCM port connects a low-latency memory to the processor, and this TCM port has Instruction TCM (ITCM) and Data TCM (DTCM) interfaces. ITCM is a 64-bit memory interface and DTCM is a two 32-bit memory interfaces (D0TCM and D1TCM). WebOS do that. The microcode format is very specific to each version of each CPU, it is not standard, it is not documented, and it is protected by unspecified cryptographic algorithms, so that a microcode update is, from the point of view of the OS, an opaque blob straight from Intel or AMD. Microcode opens the possibility of a hidden backdoor.
