The present invention provides a microcontroller, wherein the microcontroller includes a processor, a first memory and a cache controller. The first memory includes at least a working space. The cache controller is coupled to the first memory, and is arranged for managing the working space of the first memory, and dynamically loading at least one object from a second memory to the working space of the first memory in an object-oriented manner.

A method of writing data to persistent storage includes (a) for each data block of a set of data blocks, storing data of that data block at an offset within a log segment of the persistent storage in conjunction with a logical block address (LBA) of that data block on the persistent storage, a size of the log segment being larger than a size of each data block, (b) identifying a particular log segment of the persistent storage that has become filled with data blocks, and (c) upon identifying the particular log segment as having become filled, inserting pointers to respective data blocks stored within the particular log segment into respective locations defined by the respective LBA of each respective data block within a map tree.

Methods and apparatus for supporting cached volumes at storage gateways are disclosed. A storage gateway appliance is configured to cache at least a portion of a storage object of a remote storage service at local storage devices. In response to a client's write request, directed to at least a portion of a data chunk of the storage object, the appliance stores a data modification indicated in the write request at a storage device, and asynchronously uploads the modification to the storage service. In response to a client's read request, directed to a different portion of the data chunk, the appliance downloads the requested data from the storage service to the storage device, and provides the requested data to the client.

Aspects of the present disclosure relate to systems and methods for improving performance of a partial cache collapse by a processing device. Certain embodiments provide a method for performing a partial cache collapse procedure, the method including: counting a number of cache lines that satisfy an eviction criteria based on a deterministic cache eviction policy in each cache way of a group of cache ways; selecting at least one cache way from the group for collapse, based on its corresponding number of cache lines that satisfy the eviction criteria; and performing the partial cache collapse procedure based on the at least one cache way selected from the group for collapse.

The web cookie data specifying a web cookie associated with an encoded domain is received. An identifier of an original domain corresponding to the encoded domain is determined. The web cookie data is stored in a stored web cookie in a manner that associates the web cookie data to the original domain but the stored web cookie is scoped to a domain scope that includes the encoded domain.
