A Fully Synthesizable Bluetooth Baseband Module for a System-on-a-Chip

Abstract

Bluetooth is a specification for short‐range wireless communication using the 2.4 GHz ISM band. It emphasizes low complexity, low power, and low cost. This paper describes an area‐efficient digital baseband module for wireless technology. For area‐efficiency, we carefully consider hardware and software partitioning. We implement complex control tasks of the Bluetooth baseband layer protocols in software running on an embedded microcontroller. Hardware‐efficient functions, such as low‐level bitstream link control; host controller interfaces (HCIs), such as universal asynchronous receiver transmitter (UART) and universal serial bus (USB) interfaces; and audio Codec are performed by dedicated hardware blocks. Furthermore, we eliminate FIFOs for data buffering between hardware functional units. The design is done using fully synthesizable Verilog HDL to enhance the portability between process technologies so that our module can be easily integrated as an intellectual property core on system‐on‐a‐chip (SoC) ASICs. A field programmable gate array (FPGA) prototype of this module was tested for functional verification and realtime operation of file and bitstream transfers between PCs. The module was fabricated in a 0.25‐µm CMOS technology, the core size of which was only 2.79 mm×2.80 mm.

Liderazgo femenino en un sector masculinizado. El caso de la automoción en España

“…El sector de la automoción en concreto es uno de los que en las últimas décadas más se ha visto afectado por una notable actividad transformadora y modernizadora que implica, entre otras cosas, la aplicación de novedosas tecnologías (tanto en la parte productiva como comercial), la automatización de los procesos, el reto ambiental y la innovación verde, la electrificación de vehículos o la reciente escasez global de suministro de componentes electrónicos semiconductores (Cano-Kollmann et al, 2017;Gutiérrez-Aragón, Fondevila-Gascón y Mir-Bernal, 2019;Pardi, 2019;Vecchiato et al, 2019;De-Jorge-Moreno y Merino, 2020;Gohoungodji et al, 2020;Chun, Kim y Roh, 2021).…”
