Hackware v2.7: IoT Special Hackware Quiz The important thing in Hackware is not triumph, but the struggle; the essential thing is not to have conquered but to have learned well. To spread these principles is to build up a strong and more valiant and, above all, more creative and generous community ! Brahim HAMADI CHAREF (Adapted from Pierre de Coubertin)
Rules of the quiz • 12 questions • 4 possible answers, only one right ! • Pen and paper (old school days) • Results at Hackware v2.8 • No Winners and losers, just for fun ! Prizes include hardware+bits and books !
Electronics Question 1 Resistors are the essential element of electronics. They have 5 bands 3 digit with multiplier and tolerance. Tolerance can be 10% Silver and 5% with Gold but can also be 2% and 1%. What is the color of 1% ? Brown ? Red ? Orange ? Yellow ?
USD100 EU100 FREE MYR100 FPGA Question 2 Vivado Design Suite is a software suite produced by Xilinx for synthesis and analysis of HDL designs, superseding Xilinx ISE with additional features for system on a chip development and high-level synthesis. Field-Programmable Gate Arrays (FPGAs) are know to be expensive, development boards are getting cheaper but this tool is
Electronics Question 3 Transistors come in different packages and power rating. For power angry amplifiers TO-3 package handle the most heat. What is the 4th one called ? TO-7 ? TO-13 ? TO-18 ? TO-51 ? TO-92 TO-220 TO-3 TO-XX
FPGA Question 4 Xilinx includes in its FPGAs high-performance Digital Signal Processing blocks called DSP slice, what is the top of range DSP slice ? DSP48E1 DSP48E2 DSP48E5 DSP48Ex
Electronics Question 5 In electromagnetism and electronics, inductance is the property of an electrical conductor by which a change in current through it induces an electromotive force. Its Standard Unit is in Johnny Henry Harry Terry
Electronics Question 6 Due to their different behavior in frequency domain an Capacitor and Resistance (CR) network filter is known to be a Low Pass (LP) Band Pass (BP) High Pass (HP) Employment Pass (EP)
Spartan 7 Virtex 7 Kintex 7 Artix 7 FPGA Question 7 Over the years Xilinx progressively introduced, as its FPGA families, the Spartan, Virtex, Kintex, Artix, UltraScale, etc. ... What is the most recent one ?
Electronics Question 8 When capacitors are arranged in parallel, the equivalent capacitance is i.e. Ceq = C1 + C2 + C3 + .... When capacitors are arranged in series, the equivalent capacitance is Ceq = C1 + 2xC2 + 3xC3 + ... Ceq = C1 x C2 x C3 x ... 1/Ceq = 1/C1 + 1/C2 + 1/C3 + ... Ceq = median(C1 C2 C3 ... )
Hardware Question 9 If one makes a tradeoff between flexibility, programming attraction, performance, area and power efficiency, cost, etc. which of the following is the coolest technology around ? CPU GPU FPGA ASIC
IoT Question 10 IoT is the hot topic ... to give and idea of the scale ... 18.6 billion microcontrollers were shipped in 2014, and 10.4 billion RFID tags in 2016 ... How many billions of IoT devices by 2020 ? 50 billion No-one knows ! 256 billion 1 trillion
IoT Question 11 Current IoT devices make extensive use of sensors with interfaces defined decades ago (1-Wire, RS232, I2C, SPI, etc. ) The MIPI alliance has recently introduced as a white paper a new interface, it is RS696 (3x RS232) SPIx (extended) I3C (I cube C) USB4 (4x USB)
IoT Question 12 At a recent IoT talk with UnaBiz the Unashield was presented. Inquires were made for its price. So how much it is ? SG$ 20 !! Free !! SG$65 SG$ 100
Electronics Question 4 Transistors (T) are the basis of electronics for amplifiers they have Anode (A) considered Negative (N) and Cathode (C) is considered Positive (P). Which transistor would get the most vote in Singapore ? PNP NPN PAP TPP
