This approach offers the low power and efficiency of an ASIC along with the ease ofFPGA configuration, particularly beneficial for the use case of machine learning in the data pipeline of next-generation collider experiments. An open-source framework called \"FABulous\" was used to design eFPGAs using 130 nm and 28 nm CMOS technology nodes, which were subsequently fabricated and verified through testing. The capability of an eFPGA to act as a front-end readout chip was assessed using simulation of high energy particles passing through a silicon pixel sensor. A machine learningbased classifier, designed for reduction of sensor data at the source, was synthesized and configured onto the eFPGA. A successful proof-of-concept was demonstrated through reproduction of the expected algorithm result on the eFPGA with perfect accuracy. Further development of the eFPGA technology and its application to collider detector readout is discussed.  \nKeywords: Reconfigurable Computing; Open Source; FPGA; ASIC; Machine Learning  \nArXiv ePrint: 2404.17701  \n\n| Contents\u003Cbr>1 Background\u003Cbr>2 Developments in 130nm CMOS\u003Cbr>2.1 eFPGA Customization\u003Cbr>2.2 ASIC Digital Architecture\u003Cbr>2.3 Fabrication\u003Cbr>2.4 Testing Results\u003Cbr>2.4.1 Simple Counter Test\u003Cbr>2.4.2 ASIC Power Draw\u003Cbr>3 Motivation for Transitioning from 130nm to 28nm CMOS Technology\u003Cbr>4 Developments in 28nm CMOS\u003Cbr>4.1 eFPGA Customization\u003Cbr>4.2 ASIC Digital Architecture\u003Cbr>4.3 Fabrication\u003Cbr>4.4 Testing Results\u003Cbr>4.4.1 Simple Counter Test\u003Cbr>4.4.2 ASIC Power Draw\u003Cbr>4.4.3 AXI Stream Loopback in the eFPGA\u003Cbr>5 Application for Machine Learning-based At-Source Processing\u003Cbr>6 Summary | 1\u003Cbr>3\u003Cbr>3\u003Cbr>3\u003Cbr>4\u003Cbr>5\u003Cbr>5\u003Cbr>6\u003Cbr>6\u003Cbr>7\u003Cbr>7\u003Cbr>7\u003Cbr>8\u003Cbr>9\u003Cbr>9\u003Cbr>9\u003Cbr>10\u003Cbr>11\u003Cbr>14 |\n| --- | --- |\n\n1 Background  \nSilicon microelectronics technology is a key part of the modern computational paradigm, offering high performance and low power options for data processing tasks. A diversification of microchip designs offers the ability to customize computing solutions to a particular problem. Common options such as application-specific integrated circuits (ASICs) or field-programmable gate arrays (FPGAs) offer trade-offs between performance, power consumption, and flexibility to suit a wide variety of applications. While an FPGA is fully customizable, it draws more power than an ASIC; however, the ASIC requires considerable expertise to design, and is fixed to a certain task once fabricated. Microelectronics remain a rapidly developing field, with advances promising to deliver even denser logic, faster processing, and novel designs.  \nIn parallel, artificial intelligence and machine learning (AI/ML) have become essential tools in data science. In light of increasing dataset sizes and expanding computational capacity, ML-based  \nmethodology can execute common scientific tasks such as signal-noise classification, regression of key quantities, fast generation of simulation, or anomaly detection, with good efficiency and performance. Leveraging ML in these scenarios requires a high degree of reconfigurability in computing architecture, such that weights and biases of a model, as well as the model itself, can be updated throughout training and over time as the task evolves.  \nIn the sciences, many data proces","cbCaitfWWnk3KdM3","https://ap.wps.com/l/cbCaitfWWnk3KdM3","pdf",7348580,1,17,"English","en",105,"# Background\n# Developments in 130nm CMOS\n## eFPGA Customization\n## ASIC Digital Architecture\n## Fabrication\n## Testing Results\n### Simple Counter Test\n### ASIC Power Draw\n# Motivation for Transitioning from 130nm to 28nm CMOS Technology\n# Developments in 28nm CMOS\n## eFPGA Customization\n## ASIC Digital Architecture\n## Fabrication\n## Testing Results\n### Simple Counter Test\n### ASIC Power Draw\n### AXI Stream Loopback in the eFPGA\n# Application for Machine Learning-based At-Source Processing\n# Summary","[{\"question\":\"Why consider embedded FPGA (eFPGA) technology for machine learning in collider readout systems?\",\"answer\":\"eFPGA integrates FPGA-like reconfigurable logic into an ASIC design, aiming to achieve FPGA flexibility with ASIC-like power efficiency.
