In this paper, we present the design of a baseband System-On-Chip for tracking applications in the medical environment based on the IEEE 802.15.4 standard which can be used to track patient location in hospitals. It utilizes an ARM Cortex-M1 soft-core, 16 kb of SRAM and a bus architecture based on the AHB-Lite specification. The IEEE 802.15.4 MAC primitives are implemented in a Flash-ROM of 32 kb...
This article presents the hardware software co-optimized implementation of the IEEE 802.15.4 protocol for a Wireless image Sensor Network (WiSN) node SoC. In order to to minimize the power consumption and hardware software implementation cost, a power and cost aware partition scheme is introduced. Then the optimized hardware accelerator is designed and validated with software driver/stack based on...
Based on the study of the characteristics of ZigBee technology and the analysis of the structure of wireless sensor networks, here proposed a new reliable, flexible and inexpensive remote lighting control system based on ZigBee technology and SoC (system-on-chip) solution. This paper emphasizes on the implementation of ZigBee protocol and data communication flow. The hardware and software design are...
