Routing is an important step in the design of integrated circuits. It involves generating metal wires to connect the pins of same signal while obeying manufacturing design rules. Before routing is performed on the design, cell placement has to be carried out wherein the cells used in the design are placed. But the connections between the pins of the cells pertaining to same signal need to be made. At the time of placement, there are only logical connections between these pins. The physical connections are made by routing. More generally speaking, routing is to locate a set of wires in routing space so as to connect all the nets in the netlist taking into consideration routing channels’ capacities, wire widths and crossings etc. The objective of routing is to minimize total wire length and number of vias and that each net meets its timing budget. The tools that perform routing are termed as routers. You typically provide them with a placed netlist along with list of timing critical nets. These tools, in turn, provide you with the geometry of all the nets in the design.

In the VLSI Physical Design Stage, Floorplanning is an essential step, as it is an effective means to manage circuit design complexity, which is increasing with the advancement in technology. Floorplanning involves determining the locations, shape, size of modules in a chip and as such it estimates the chip area, delay and the wiring congestion, thereby providing a ground work for layout. Computationally, it is a NP hard problem. So many researchers from time to time have suggested various heuristics and metaheuristic approaches for solving the VLSI Floorplan Problem. The Floorplan representation is another important aspect of the Floorplanning Stage. Representations have a great impact on the complexity of the Floorplan design. In this paper, we survey the VLSI Floorplanning problem which includes studying and comparing the different optimization algorithms and the representations involved in the VLSI Floorplanning problem. Additionally we suggest some of the new approaches for solving the floorplanning problem which has not yet been employed in this regard.

MPU Serial Interface (3-wire SPI)
The 3-wire serial interface consists of serial clock SCLK, serial data SDIN, and CSB.
There are altogether 9-bits that will be shifted into the shift register on every ninth clock in sequence: D/C bit, D7 to D0 bit.
The D/C bit (first bit of the sequential data) will determine the following data byte in the shift register is written to the Display Data RAM (D/C bit = 1) or the command register (D/C bit = 0).

IMAX3: Amazing Dataflow-Centric CGRA and its Applications
I present this slide to all hungry engineers who are tired of CPU, GPU, FPGA, tensor core, AI core, who want some challenging one with no black box inside, and who want to improve by themselves.
セル生産方式におけるロボットの活用には様々な問題があるが,その一つとして 3 体以上の物体の組み立てが挙げられる.一般に,複数物体を同時に組み立てる際は,対象の部品をそれぞれロボットアームまたは治具でそれぞれ独立に保持することで組み立てを遂行すると考えられる.ただし,この方法ではロボットアームや治具を部品数と同じ数だけ必要とし,部品数が多いほどコスト面や設置スペースの関係で無駄が多くなる.この課題に対して音𣷓らは組み立て対象物に働く接触力等の解析により,治具等で固定されていない対象物が組み立て作業中に運動しにくい状態となる条件を求めた.すなわち,環境中の非把持対象物のロバスト性を考慮して,組み立て作業条件を検討している.本研究ではこの方策に基づいて,複数物体の組み立て作業を単腕マニピュレータで実行することを目的とする.このとき,対象物のロバスト性を考慮することで,仮組状態の複数物体を同時に扱う手法を提案する.作業対象としてパイプジョイントの組み立てを挙げ,簡易な道具を用いることで単腕マニピュレータで複数物体を同時に把持できることを示す.さらに,作業成功率の向上のために RGB-D カメラを用いた物体の位置検出に基づくロボット制御及び動作計画を実装する.
This paper discusses assembly operations using a single manipulator and a parallel gripper to simultaneously
grasp multiple objects and hold the group of temporarily assembled objects. Multiple robots and jigs generally operate
assembly tasks by constraining the target objects mechanically or geometrically to prevent them from moving. It is
necessary to analyze the physical interaction between the objects for such constraints to achieve the tasks with a single
gripper. In this paper, we focus on assembling pipe joints as an example and discuss constraining the motion of the
objects. Our demonstration shows that a simple tool can facilitate holding multiple objects with a single gripper.

概要:リソース効率に優れた特徴点マッチングのための軽量なアーキテクチャ「XFeat(Accelerated Features)」を提案します。手法は、局所的な特徴点の検出、抽出、マッチングのための畳み込みニューラルネットワークの基本的な設計を再検討します。特に、リソースが限られたデバイス向けに迅速かつ堅牢なアルゴリズムが必要とされるため、解像度を可能な限り高く保ちながら、ネットワークのチャネル数を制限します。さらに、スパース下でのマッチングを選択できる設計となっており、ナビゲーションやARなどのアプリケーションに適しています。XFeatは、高速かつ同等以上の精度を実現し、一般的なラップトップのCPU上でリアルタイムで動作します。
