This invention discloses an efficient QR matrix decomposition method based on FPGA for implementing systolic matrices, belonging to the field of software-defined radio signal transmission technology for airborne networks. It is based on the design of a multi-channel digital front-end implemented on an FPGA chip. The method includes: designing a general handshake coordination mechanism, designing a timing flow for systolic matrix multiplication, performing fast QR matrix decomposition single-loop operations by calculating the Householder mirror transformation matrix, designing a top-level loop pipeline for QR matrix decomposition, and finally verifying the hardware scheme of the fast QR decomposition algorithm. This invention converts resource consumption into timing consumption by designing the overall pipeline logic and loop operations, enabling fast processing and accurate decomposition of digital information in a multi-channel digital front-end on an FPGA, effectively saving on-chip resources. In addition, this invention has excellent scalability, supporting 64 to 128-bit high-precision fixed-point number formats, and the data matrix order can reach up to 128.

An image formation system includes a digital front end and an image forming apparatus. When communication is interrupted due to a communication error during sending of image data from the digital front end to the image forming apparatus, the image forming apparatus does printing halfway in accordance with already received part of the image data. The digital front end stores information on pages of the image data left unprinted by the image forming apparatus and, after restart of the digital front end and the image forming apparatus, sends the information on the pages left unprinted to the image forming apparatus. The image forming apparatus resumes the printing in accordance with the information on the pages left unprinted.

This disclosure is directed to digital front-end circuitry of a memory device having widened operating frequency bandwidth. The digital front-end circuitry may include a receiver including a variable gain amplifier (VGA) and a continuous time linear equalizer (CTLE) integrated on three cascaded circuit stages. A first stage of the three cascaded circuit stages may include a first portion of the VGA and a first portion of the CTLE, a second stage may include a remaining portion of the VGA, and a third stage may include a remaining portion of the CTLE. Having three cascaded circuit stages (e.g., including the remaining portion of the CTLE) as opposed to two cascaded stages may widen the operating frequency bandwidth of the receiver. The third stage may be programmable to be activated or deactivated.

Systems and methods for identify errors in a transcript using an LLM. System comprises a digital front end; a backend computer system in communication with the digital front end; and a LLM in communication with the backend computer system. The LLM is configured to receive, via the digital front end: a list of words and phrases; a list of error categories; and a transcript, in a machine-readable format, for transcript correction by the LLM. The LLM is configured, via prompts: to consider a word or phrase in the transcript to possibly be in error if the word or phrase matches one error category in the list of error categories and if the word or phrase is phonetically similar to a word or phrase in the list of correct words and phrases; to assign a confidence score to each word or phrase considered to possibly be in error in the transcript; to ignore words or phrases considered possibly in error if the assigned confidence score is lower than a certain threshold value; and return a list of possible errors in the transcript in a machine-readable transcription error output format. The LLM is further configured, based on the prompts, to generate the list of possible errors in the transcript in the machine-readable transcription error output format.

A printing system includes a printing device having one or more paper trays. A print job is received for the printing device having at least one media attribute. A digital front end (DFE) of the printing device parses a print ticket for the print job to determine the media attribute. The media attribute is compared to a paper catalog for the printing device. A list of media catalog entries is generated from the paper catalog that supports the media attribute. The DFE determines whether a media catalog entry of the list of media catalog entries is assigned to a paper tray. The print job is matched to the paper tray and the media related to the media catalog entry. The print job is processed using the paper in the paper tray.

A printing system includes a printing device having a digital front end (DFE). The DFE communicates with a cloud server system within the printing system. The cloud server system includes a paper catalog for the papers used at the printing devices within the printing system. For each printing device, the cloud server system defines a set of papers based on data or information related to the printing device or to a paper being used at the printing device. The set of papers is a number of papers from the paper catalog selected based on the data. The set of papers are provided to the DFE of the printing device. Paper usage is monitored at the printing device and used to adjust the papers within the set of papers stored within the DFE.

A printing system includes a printing device having a digital front end (DFE). The DFE communicates with a cloud server system within the printing system. The printing system is configured to print imposed pages having pages or documents having output intents. A first page of the imposed page has a first output intent. A second page of the imposed page has a second output intent. The first output intent relates to a first gamut applicable to color printing the first page. The second output intent relates to a second gamut applicable to color printing the second page. A page-level output intent for the imposed is set to the first output intent or the second output intent based on an evaluation of the first gamut and the second gamut.

This application provides a method, apparatus, storage medium, and electronic device for generating padding signals. The method includes: acquiring multiple subcarrier signals corresponding to each symbol of a radio frame signal, and performing inverse fast Fourier transform processing on the subcarrier signals corresponding to each symbol to obtain a time-domain baseband sampling sequence corresponding to each symbol; truncating the time-domain baseband sampling sequence to obtain a truncated short-time-domain signal sequence, and superimposing an raised cosine window function on the short-time-domain signal sequence to obtain a smoothed short-time-domain signal sequence; inputting the smoothed short-time-domain signal sequence into a digital front-end module for processing to obtain multiple padding signals, wherein the padding signals are used to preempt the channel before transmitting the radio frame signal. This solves the problem of large time delays in existing schemes that transmit padding signals according to the normal service signal flow.
