While silicon based data transceivers at mm-wave frequencies have become increasingly mature in recent years [1,2,3], the primary focus of the circuit community remains on the design of mm-wave front-ends to achieve higher data rates through higher-order modulation and beamforming techniques. However, the sustainability of such mm-wave systems when integrated in a SoC has not been addressed in the context of die performance yield and device aging.

Until recently, phased array systems exploited dedicated RF technologies leading to relatively costly systems, e.g. for nautical, airplane radar systems, and satellite communication. More recently, low-cost highly integrated beamforming concepts received considerable interest in academia but also industry, enabling consumer applications e.g. in base-stations for macro- and femto-cells, car-radar and 60GHz wideband radio links. (Bi-)CMOS beamforming techniques are at the heart of such systems. This forum reviews beamforming techniques suitable for IC-integration, and discusses related (Bi-)CMOS transceiver designs. Several techniques will be discussed, e.g. RF phase-shifting, LO-phase shifting, I/Q Vector modulation and digital processing. Also the relation between key radar and communication system requirements and transceiver-IC requirements will be considered.

Conventional routers use distinct logic blocks for routing data and handling arbitration. At higher radices, connections between these blocks become a bottleneck, limiting router scalability and degrading performance. Recently, two switch topologies merged the data routing fabric with arbitration control, avoiding this bottleneck. However, relies on centralized control for channel allocation, limiting performance, while restricted to a small set of fixed priorities, rendering input ports prone to starvation. In addition, ever larger CMPs will require continued increases in bandwidth over previous designs. To address these issues, we present a 64x64 single-stage swizzle-switch network (SSN) with 128b data buses (8192 total input/output wires). The SSN can connect any input to any output, including multicast. It has a peak measured throughput of 4.5Tb/s at 1.1V in 45nm SOI CMOS at 25°C. The SSN's key features are: 1) a single-cycle least-recently granted (LRG) priority arbitration technique that reuses the already present input and output data buses and their drivers and sense amps; 2) an additional 4-level message-based priority arbitration for quality of service (QoS) with 2% logic and 3% wiring overhead; 3) a bidirectional bitline repeater that allows the router to scale to >;8000 wires. These features result in a compact fabric (4.06mm2) with throughput gain of 2.1 x over at 3.4Tb/s/W efficiency, which improves to 7.4Tb/s/W at 600mV.","PeriodicalId":255282,"journal":{"name":"2012 IEEE International Solid-State Circuits Conference","volume":"398 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116399369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we demonstrate that a hybrid communication mechanism supporting both message passing and shared memory can provide both higher performance and energy efficiency. This 16-core processor has 3 key features: (1) A cluster-based hierarchical architecture supporting both shared-memory and message-passing communication. (2) A cache-free memory hierarchy with an extended register file, small private memory and moderate shared memory to avoid complex cache coherence issues and achieve high energy efficiency by keeping data accesses local. (3) A hardware-aided mailbox mechanism to accelerate the synchronization procedure between different processor nodes. With these techniques, our multicore processor can provide high performance for many applications.
