Abstract: Emulating scratchpad functionality using caches in processor-based devices is disclosed. In one aspect, each cache line within a cache of a processor-based device is associated with a corresponding scratchpad indicator indicating whether the corresponding cache line is exempt from the replacement policy used to select a cache line for eviction. Upon receiving data that corresponds to a memory access operation indicated as requiring scratchpad functionality, the cache controller stores the data in a cache line of the cache, and then sets the corresponding scratchpad indicator for the cache line. Subsequently, the cache controller emulates scratchpad functionality by allowing conventional memory read and write operations to be performed on the cache line, but does not apply its replacement policy to that cache line when selecting a cache line as a candidate for eviction. In this manner, the cache line may remain in the cache for use as scratchpad memory by software.

Abstract: Apparatus and associated methods relate to constructing a resource and attribute tasking solution to complete a user's objective with resource and attribute characteristics defining the tasked objects, in response to receiving a task definition, and satisfying a task definition constraint. An object includes of a set of resource and attribute dimensions each of which have a set of possible values. A tasking solution is the union of all valid solution vectors in the dimension space. The solution identifies all valid values to present to a user or other agent to make further decisions on further constraining resource and attribute characteristics for a final materializable tasking. In an illustrative example, the objective may be mapping resource supply to task demand. The task demand may be, for example, delivering a database-as-a-service platform configured based on rules generated to satisfy task definition capacity constraints.
