Recently, wireless technology experiences a fast growth to meet user demand and push toward the boundary limit of system performance. The simulation and verification framework play important role for accelerating investigation of technology proof of concept, field-trial, and large-scale commercial prototyping. In this paper, we present system-level simulation of heterogeneous model and unified HW/SW framework, particularly for next generation wireless system. The proposed framework includes a unified HW/SW co-evaluation methodology, the flexible HW/SW architecture, and fast HW/SW co-evaluation. The co-evaluation is carried out by employing hardware-in-the loop scheme that covers various abstraction level of simulation, from algorithm-level into physical-level simulation, with respect to system level simulation. The proposed co-verification framework allows a comprehensive system evaluation for a wireless system, involving various system parameters, hardware impairments, different channel conditions and cross-layer evaluations with fast run-time evaluations. Additionally, we also show an application example of multi-user wireless communication system and its experimental evaluations.

Multiprocessing can be considered the most characteristic common property of complex digital systems. Due to the more and more complex tasks to be solved for fulfilling often conflicting requirements (cost, speed, energy and communication efficiency, pipelining, parallelism, the number of component processors, etc.), the so called heterogeneous multiprocessor architectures (HMPA) have become unavoidable. The component processors of such systems may be not only general purpose CPUs or cores, but also DSPs, GPUs, FPGAs and other custom hardware components as well. The hierarchy of the component processors and the data transfer organization between them are strongly determined by the task to be solved and by the priority order of the requirements to be fulfilled. For each component processor of HMPAs, a subtask must be defined based on the requirements and their priority orders. The definition of the subtasks, i.e. the decomposition of the task influences strongly the cost and performance of the whole system. Therefore, comparing and evaluating the effects of different task decompositions performed by applying systematic algorithms may help the designer to approach the optimal decisions in the system level synthesis phase. For this purpose, the paper presents a novel method based on combining the decomposition and the modified high level synthesis algorithms. The application of the method is illustrated on redesigning and evaluating in some versions of a high performance embedded multiprocessing system.
多处理被认为是复杂数字系统最典型的共同特性。由于需要解决越来越复杂的任务,以满足经常相互冲突的需求(成本、速度、能源和通信效率、流水线、并行性、组件处理器的数量等),因此所谓的异构多处理器架构(HMPA)已成为不可避免的。这种系统的组件处理器不仅可以是通用的cpu或核心,还可以是dsp、gpu、fpga和其他定制硬件组件。组件处理器的层次结构和它们之间的数据传输组织在很大程度上取决于要解决的任务和要满足的需求的优先级顺序。对于hmpa的每个组件处理器,必须根据需求及其优先级顺序定义子任务。子任务的定义,即任务的分解对整个系统的成本和性能有很大的影响。因此,比较和评估应用系统算法进行不同任务分解的效果可以帮助设计者在系统级综合阶段接近最优决策。为此,本文提出了一种将分解与改进的高级综合算法相结合的新方法。并举例说明了该方法在高性能嵌入式多处理系统若干版本的重新设计和评估中的应用。

Current hybrid network-on-chip designs in manycore systems are agnostic to the application requirements and thus are provided for general cases. This results in high cost in the manycore systems design, wasted energy and performance. We observe that the cost of network-on-chip designs can be reduced by optimizing the application-specific traffic onto the system. This paper presents mincostflow-based heuristic algorithm (LINCA) that minimizes the quantification of hybrid routers corresponding to the application-specific traffic for manycore systems. LINCA guarantees the performance of hybrid networks on chip. Its results are validated against the manycore system architecture. Our evaluations show that LINCA can reduce significant cost of using hybrid routers in the manycore systems. It reduces cost by 84 percent on average across a variety of applications, compared with all of hybrid routers being deployed in the network without using optimization model.
目前在多核系统中的混合片上网络设计对应用需求是不可知的,因此是为一般情况提供的。这导致了多核系统设计的高成本,浪费了能源和性能。我们观察到,通过优化特定于应用程序的系统流量,可以降低片上网络设计的成本。本文提出了一种基于最小成本流的启发式算法(LINCA),该算法最大限度地减少了多核系统中对应于特定应用流量的混合路由器的量化。LINCA保证了片上混合网络的性能。其结果在多核系统架构下得到验证。我们的评估表明,LINCA可以显著降低在多核系统中使用混合路由器的成本。与没有使用优化模型的网络中部署的所有混合路由器相比,它在各种应用程序中平均降低了84%的成本。

This paper presents a low power programmable 12-bit Two Step successive approximation register (SAR) — Flash analog-to-digital converter architecture for communication and bio-potential signal processing applications. The proposed ADC consists of two identical 6-bit SAR-Flash analog-to-digital converter (ADC) stages combined with a pipelined inter-stage gain amplifier to improve performance, reduce area, and power consumption. The 6-bit SAR-Flash ADC stage consists of low power and high performance 3-bit SAR ADC and 3-bit flash ADC. The proposed ADC architecture results are compared with recent conventional SAR ADCs and hybrid ADCs at different sampling frequencies. The ADC is designed in 90nm standard CMOS process occupies 0.1225 mm2 area. The performance parameters of the proposed ADC design are found to be differential nonlinearity (DNL) of ±0.28 LSB, integral non-linearity (INL) of ±0.52 LSB, signal-to-noise-and-distortion ratio (SNDR) of 67.4 dB, spurious-free dynamic range (SFDR) of 79.6 dB, and effective number of bits (ENOB) of 10.9 bits with input frequency of 15 MHz @ 200 MS/s sampling frequency at 1.0 V supply voltage. The power consumption of the ADC at lower sampling frequency at 500 KS/s is 1.47 pW and at 200 MS/s it is 1.35 mW.

In the recent years, microfluidic technology has paved the way for so-called Labs-on-Chips (LoCs) — a convenient and cost-effective way to conduct biochemical, biological, or medical experiments. Instead of conducting tests manually in a fully equipped lab using up lab equipment and human resources, LoCs allow us to conduct biochemical and medical experiments on a small chip. This requires much smaller sample/reagent volumes and allows for a significantly higher throughput.

Off-grid medium-power (1–10 W) systems require either battery-or supercapacitor-based ambient energy harvesting for sustaining their operation. Supercapacitor-based harvesters are advantageous in autonomous field systems due to their extended lifetime, easy power management, and low maintenance requirement; however, they can reach only up to 10% of the energy density of rechargeable batteries. To overcome this energy density challenge, hybrid power sources, such as solar or wind, can be advantageously utilized in harvesting systems. The complementary power supply characteristics of solar and wind can substantially reduce the required supercapacitor buffer size compared with solar-only or wind-only systems. In the literature, no supercapacitor-based hybrid harvesting system design exists for 1–10 W range. In this paper, we develop and experimentally validate three different categories of supercapacitor-based harvesting systems that are capable of simultaneously harvesting solar/wind (hybrid) power sources.
离网中等功率(1 - 10w)系统需要基于电池或超级电容器的环境能量收集来维持其运行。基于超级电容器的收割机在自主现场系统中具有优势,因为它们寿命长,易于电源管理,维护要求低;然而,它们的能量密度只能达到可充电电池的10%。为了克服这种能量密度的挑战,混合电源,如太阳能或风能,可以在收集系统中得到有利的利用。与仅太阳能或仅风能系统相比,太阳能和风能的互补供电特性可以大大减少所需的超级电容器缓冲尺寸。在文献中,没有超级电容混合收获系统的设计存在于1-10 W范围内。在本文中,我们开发并实验验证了三种不同类型的基于超级电容器的收集系统,这些系统能够同时收集太阳能/风能(混合)电源。

Power Semiconductor devices used for high voltage, high current applications dissipate lot of power thereby rapidly increasing their junction temperature to levels beyond which no SPICE (Simulation Program with Integrated Circuit Emphasis) models exist. In this paper, the design of an integrated four channel squib driver SOC (System on Chip) with four High Side (HS) drivers and four Low Side (LS) drivers is presented. 98mJ energy limited current regulating High Side (HS) driver needs the temperature information from the electro-thermal simulators like FloTHERM during the design to ensure that the powerFET operates within the thermal SOA (Safe Operating Area) without area penalty. Despite SPICE model restrictions to 200°C, this paper explains how the current regulation loop architecture is chosen to operate at peak temperatures of 400°C. The Thermal simulation results aid in the optimization of the layout of the gate-driver. Apart from the robust design, additional design measures to prevent inadvertent turn ON of the FETs and reverse protection for safety are discussed. This circuit was successfully implemented in a 40V, 0.35pm, BiCMOS process on a 4 channel airbag squib driver IC.
用于高电压、高电流应用的功率半导体器件耗散大量功率,从而迅速将其结温提高到没有SPICE(集成电路仿真程序)模型存在的水平。本文设计了一种集成了4个高侧(HS)驱动器和4个低侧(LS)驱动器的四通道单片系统(SOC)。在设计过程中,98mJ能量有限的电流调节高侧(HS)驱动器需要来自FloTHERM等电热模拟器的温度信息,以确保功率场效应管在热SOA(安全工作区域)内工作,而不会造成面积损失。尽管SPICE模型限制为200°C,但本文解释了如何选择当前的调节回路架构在400°C的峰值温度下运行。热模拟结果有助于栅极驱动器布局的优化。除了稳健设计外,还讨论了防止场效应管意外导通和反向安全保护的附加设计措施。该电路在4通道安全气囊爆燃驱动器IC上以40V, 0.35pm的BiCMOS工艺成功实现。

Novel applications demand computational resources that are provided by multiprocessor systems-on-chip (MPSoCs). At the same time, they increasingly process sensitive data and incorporate security-relevant functions like encryption or authentication. This paper discusses the implications of the MPSoC technology on security. It provides an overview of hardware-oriented techniques to enhance security (such as on-chip cryptographic key generation and hardware-supported software attestation), but also lists hardware-related threats and potential security loopholes, which designers of MPSoCs and MPSoC-based systems should be aware of.
新型应用需要由多处理器片上系统(mpsoc)提供的计算资源。与此同时,它们越来越多地处理敏感数据,并结合加密或身份验证等安全相关功能。本文讨论了MPSoC技术对安全性的影响。它概述了增强安全性的面向硬件的技术(例如片上加密密钥生成和硬件支持的软件认证),但也列出了与硬件相关的威胁和潜在的安全漏洞,这些都是mpsoc和基于mpsoc的系统的设计者应该注意的。
