Numerous articles and papers have been written on emerging non-volatile memory (NVM) over the last few decades. These emerging technologies have been hyped as either:
Embedded memories are a key component of IoT SoCs and recent applications such as Neural Network Accelerators. Unfortunately, SRAM based embedded memory has a large footprint which often covers more than 50% of the silicon area and is responsible for…
Hi experts,
Recently I want to conduct one secure-related scanning in TrustZone for some NS kernel memory.
To do this, I need at first reporting the PA of the memory from NS kernel. My idea is developing a kernel module to achieve the goal.
I write the
…Hi experts,
I'm wondering do you compile the OPTEE_OS in this instruction as arm32 or AArch64? In which script do you set the compiler for the secure OS? ( I checked the file build-optee-os.sh while I find the file exports both compilers so I'm not…
Hi,
I am trying to use arm trusted firmware with my own BL32 (with 0xFF000000 entry point as specified). I want BL31 switch to my secure world that generate smc (aftersome init) to switch to normal world.
For that I use this compilation configuration:
The memory sub-system is one of the most complex systems in a SoC, critical for overall performance of the chip. Recent years have witnessed explosive growth in the memory market with high-speed parts (DDR4/3 with/without DIMM support, LPDDR4/3) gaining…
ARM® AMBA® 5 CHI Memory Controllers work in concert with AMBA 5 CHI interconnects to provide controls to optimise data flows between many processors and the DDR memory. In this blog I am going to tell you a bit more about the work ARM is doing to create…
