“…The data acquisition and recording device designed in this part can simultaneously acquire five types of data among which 3 of them belong to PCM and the other belong to LVDS. All the data are packaged and forwarded to the composite memories then [10]. Data hybrid framing technique built on FIFO cache serves as a solution for successfully covering various data kinds over a single path while maintaining security and rapid acquisition speed.…”

“…FIFO itself has the feature of first in first out, which is conducive to one-way data transmission. Because this part of the data transmission is one-way, choose the FIFO memory as the data cache medium, relying on the FIFO for data transmission across the clock domain, so that in this design do not have to consider how to deal with the synchronization problem [10]. More energy and time can be spent on data flow and FIFO interface control.…”

An asynchronous FIFO is a classic circuit device used for caching data and accommodating the frequency of asynchronous signals. With the continuous improvement of technology, the advantages of this device in real-time transmission, multi-core processing, and data acquisition have become more apparent. As a result, the original structure has been optimized and extended using algorithm and design techniques to achieve greater efficiency and applicability in various academic and industrial applications. This article discusses several methods for optimizing FIFO in different aspects and examines how an unlocked FIFO queue is applied in a CAN bus data acquisition system, as well as its use in data hybrid framing technology. The findings show that FIFO performs exceptionally well as a cache structure, particularly in situations involving large amounts of data acquisition and real-time procession. The various optimization techniques discussed in this article include using pipeline registers, implementing a dual-clock FIFO, and employing Gray-code-based pointers. These techniques can increase the speed and reduce the power consumption of FIFO, thereby improving its overall efficiency. In addition, the article introduces the unlocked FIFO queue, which provides more flexibility than conventional locked FIFOs. Unlocked FIFO queues allow multiple cores to access the buffer simultaneously, which makes them ideal for high-performance systems. Finally, the article explores the application of FIFO in CAN bus data acquisition systems, where it is utilized as a buffer between the bus and other devices. Additionally, the use of FIFO in data hybrid framing technology is discussed, where it is essential for maintaining the integrity of the data stream.

PurposeThis paper proposes an assessment method for lean and sustainability (LS) practices for shop-floor workers, designed to evaluate their current practice culture.Design/methodology/approachThe method is developed in five phases: setting predefined indicators, constructing the assessment mechanism, implementing the assessment procedure, analyzing data and delivering results with recommendations. Validation is performed using two worker groups – line supervisors and operators – within the light-emitting diode (LED) manufacturing industry.FindingsThe results showed that workers’ familiarity and understanding of LS practices do not always correspond to their awareness levels. Key recommendations include prioritizing training for critical cases and adapting training approaches to fit the specific knowledge profiles identified.Research limitations/implicationsFirstly, the company should integrate the proposed assessment into an online platform that can automatically generate individual statistical results and priority levels. This reduces the burden of manual work and makes large-scale assessments more practical. Secondly, the study should expand to other shop-floor workers, such as technicians and engineers, to assess their knowledge profiles for future LS development initiatives.Practical implicationsThe recommendations provide managers and training departments with guidelines to revise current training approaches. The methodology is validated, enabling the identification and mapping of each worker’s knowledge profile.Originality/valueThis study presents an original assessment method for evaluating the knowledge profiles of shop-floor workers regarding LS practices. To the best of the authors’ knowledge, no prior literature has reported on an assessment method targeting this specific group. The proposed approach supports the decision-making process for better LS practices in the company.
