An archival blockchain system is disclosed that includes a cache-tier storage level where data is stored before it has met a first aging criteria, a disk-tier storage level where the data is migrated to and stored within archival blockchain blocks after it has met the first aging criteria. When the archival blockchain blocks containing the data meet a second aging criteria they are migrated to a tape-tier storage level where the disk-tier archival blockchain blocks are stored within another archival blockchain block stored on the tape-tier. This archival blockchain system also includes a blockchain appliance in digital data communication with the cache-tier, disk-tier, and tape-tier storage levels that maintains a ledger that stores data pointers to the data stored on the cache-tier, disk-tier, and tape-tier storage levels to logically link them into a contiguous data set.

Parity data associated with commands to, and indications from, a configuration register that includes a first command FIFO for receiving commands and a response FIFO for returning indications can be managed. Commands can be tracked by storing the commands in a second command FIFO and a command can be dequeued from the second command FIFO, in response to a command emerging from the response FIFO. Parity data can be generated from the data associated with a write operation, and stored in a parity latch corresponding to the configuration register, in response to the dequeued command being a successfully completed write operation. The generated parity data can be read from a parity latch corresponding to the configuration register and provided the generated parity data for return with an indication that the dequeued command is a successfully completed write operation.

Systems, apparatuses, and methods related to acceleration circuitry for posit operations are described. Signaling indicative of performance of an operation to write a first bit string to a first buffer resident on acceleration circuitry and a second bit string resident on the acceleration circuitry can be received at an DMA controller couplable to the acceleration circuitry. The acceleration circuitry can be configured to perform arithmetic operations, logical operations, or both on bit strings formatted in a unum or posit format. Signaling indicative of an arithmetic operation, a logical operation, or both, to be performed using the first and second bit strings can be transmitted to the acceleration circuitry. The arithmetic operation, the logical operation, or both can be performed via the acceleration circuitry and according to the signaling. Signaling indicative of a result of the arithmetic operation, the logical operation, or both can be transmitting to the DMA controller.

Techniques for implementing an on-demand serverless compute system that uses shared memory to share data between on-demand serverless compute applications are described. In some examples, a daemon of an edge device providing on-demand serverless compute is to: register launched one or more launched on-demand serverless applications, read a deployment configuration for an application using the one or more launched on-demand serverless applications, per the read deployment configuration, launch at least one data source and at least one data sink, per launched data source, register the launched data source with the device daemon, per launched data sink, register the launched data sink thread with the device daemon, match registered, launched data sources with registered, launched data sinks and launched on-demand serverless applications as defined in the deployment configuration, and for each match, register a connection first in, first out structure to be used to share data on an event driven basis between launched on-demand serverless applications.

A processing circuit includes a random access memory (RAM) configured to look up a first next state based on a first address simultaneously with looking up a second next state based on a second address. The first address is formed of a first current state and an input data and the second address is formed of a second current state and the input data. The processing circuit includes a state control circuit that receives the first and second next states, the first current state, and the second current state, and a first-in-first-out (FIFO) memory that stores selected ones of the first and second next states, the first current state, and the second current state. The processing circuit includes a multiplexer configured to selectively pass two states from the FIFO memory or two states from the state control circuit as a third current state and a fourth current state.

Screen response validation of robot execution for robotic process automation (RPA) is disclosed. Whether text, screen changes, images, and/or other expected visual actions occur in an application executing on a computing system that an RPA robot is interacting with may be recognized. Where the robot has been typing may be determined and the physical position on the screen based on the current resolution of where one or more characters, images, windows, etc. appeared may be provided. The physical position of these elements, or the lack thereof, may allow determination of which field(s) the robot is typing in and what the associated application is for the purpose of validation that the application and computing system are responding as intended. When the expected screen changes do not occur, the robot can stop and throw an exception, go back and attempt the intended interaction again, restart the workflow, or take another suitable action.

A semiconductor device includes a memory circuit, a first FIFO, a second FIFO and an input/output circuit. The memory circuit outputs data. The first FIFO receives data from the memory circuit and outputs data synchronously with a first clock signal. The second FIFO receives data output from the first FIFO and outputs data synchronously with the first clock signal. The input/output circuit outputs data output from the second FIFO. The second FIFO is disposed in the vicinity of the input/output circuit than the first FIFO.
