In one embodiment, the transition of the performance domains into different target states may be more rapid when controlled by the power management unit than may be possible with software control.
Flexible power modes, an intelligent peripheral management unit(PMU), dynamic clock gating and firmware-controlled power gating optimizes power for the specific application.
The No-IOMMU mode provides the user with full user-space I/O(UIO) access to a direct memory access(DMA)-capable device without a I/O memory management unit(IOMMU).
The Memory Management Unit(MMU) of the chips contains hardware firewalls, in order to keep the applications and other system software securely and reliably separate from each other.
While all MAXQ processors include a memory management unit(MMU) that allows any memory segment to be treated as code or data, the code and data buses are separate.
The GW1NRF Bluetooth FPGA product features FPGA fabric, a power optimized 32-bit microprocessor, a power management unit capable of power as low as 5nA and a Bluetooth 5.0 Low Energy radio.
The processor has a full-featured Memory Management Unit(MMU) supporting a 40-bit physical address space and page sizes up to 16 megabytes(MBs), giving designers the ability to directly address a terabyte of memory with faster data access and higher system performance.
Although SheepShaver does have Ethernet support and CD-quality sound output, SheepShaver does not emulate a memory management unit, as is the case with Basilisk II, and thus cannot run later versions of Mac OS 9 or any version of Mac OS X, which is best emulated by PearPC.
This vulnerability is similar to CVE-2017-5754(aka"Meltdown") but exploits an interaction between the Memory Management Unit(MMU) and the L1 Data Cache under speculation when performing virtual to physical memory address translation.
