Abstract

Techniques are described for providing consistent memory operations and security across electronic circuitry components having disparate memory and/or security architectures when integrating such disparately architected components within a single system, such as a system on chip. A programmable logical hierarchy of isolated memory region (IMR) enforcement circuits is provided to protect such IMRs, allowing or preventing memory access requests from one of multiple distinct circuitry components based on configuration registers for the IMR enforcement circuits. Integration of multiple trust domain architectures associated with the multiple distinct circuitry components is facilitated via trust domain conversion bridge circuitry that includes translation logic for generating information in accordance with a first trust domain architecture based on information provided in accordance with a distinct second trust domain architecture.
