Providing memory management functionality using aggregated memory management units (MMUs), and related apparatuses and methods are disclosed. In one aspect, an aggregated MMU is provided, comprising a plurality of input data paths including each including plurality of input transaction buffers, and a plurality of output paths each including a plurality of output transaction buffers. Some aspects of the aggregated MMU additionally provide one or more translation caches and/or one or more hardware page table walkers The aggregated MMU further includes an MMU management circuit configured to retrieve a memory address translation request (MATR) from an input transaction buffer, perform a memory address translation operation based on the MATR to generate a translated memory address field (TMAF), and provide the TMAF to an output transaction buffer. The aggregated MMU also provides a plurality of output data paths, each configured to output transactions with resulting memory address translations.

A method and system for adjusting bandwidth within a portable computing device based on danger signals monitored from one on more elements of the portable computing device are disclosed. A danger level of an unacceptable deadline miss ('UDM') element of the portable computing device may be determined with a danger level sensor within the UDM element. Next, a quality of service ('QoS') controller may adjust a magnitude for one or more danger levels received based on the UDM element type that generated the danger level and based on a potential fault condition type associated with the particular danger level. The danger levels received from one UDM element may be mapped to at least one of another UDM element and a non-UDM element. A quality of service policy for each UDM element and non-UDM element may be mapped in accordance with the danger levels.
