A storage cluster is provided. The storage cluster includes a plurality of storage nodes, each of the plurality of storage nodes having nonvolatile solid-state memory and a plurality of operations queues coupled to the solid-state memory. The plurality of storage nodes is configured to distribute the user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can access the user data with a failure of two of the plurality of storage nodes. Each of the plurality of storage nodes is configured to determine whether a read of 1 or more bits in the solid-state memory via a first path is within a latency budget. The plurality of storage nodes is configured to perform a read of user data or metadata via a second path, responsive to a determination that the read of the bit via the first path is not within the latency budget.

A controller is coupled to a non-volatile memory device and a host. The controller is configured to perform a cyclic redundancy check on map data associated with user data stored in the memory device, generate an encryption code based on a logical address included in the map data, generate encrypted data through a logical operation on the encryption code and the map data, and transmit the encrypted data to the host.

A method includes receiving a write request to store a data object; identifying object parameters associated with the data object; selecting a memory type based on the identified object parameters; selecting a selected memory based on the memory type; and facilitating storage of the data object in the selected memory, wherein the data object is dispersed error encoded.

An error detection and correction method for a flash memory includes: a setting step, setting selection information to select a first error detection and correction function for performing 1-bit error detection and correction or a second error detection and correction function for performing multiple-bit error detection and correction; and an executing step, performing the first error detection and correction function or the second error detection and correction function based on the selection information during a read operation or a write operation.

A multi-core processor configured to improve processing performance in certain computing contexts is provided. The multi-core processor includes multiple processing cores that implement barrel threading to execute multiple instruction threads in parallel while ensuring that the effects of an idle instruction or thread upon the performance of the processor is minimized. The multiple cores can also share a common data cache, thereby minimizing the need for expensive and complex mechanisms to mitigate inter-cache coherency issues. The barrel-threading can minimize the latency impacts associated with a shared data cache. In some examples, the multi-core processor can also include a serial processor configured to execute single threaded programming code that may not yield satisfactory performance in a processing environment that employs barrel threading.
