INTEL INTRODUCES LOIHI – A SELF LEARNING PROCESSOR THAT MIMICS BRAIN FUNCTIONS

Intel has developed a first-of-its-kind self-learning neuromorphic chip – codenamed Loihi. It mimics the animal brain functions by learning to operate based on various modes of feedback from the environment. Unlike convolutional neural network (CNN) and other deep learning processors, Intel’s Loihi uses an asynchronous spiking model to mimic neuron and synapse behavior in a much closer analog to animal brai ...

PAC1934 – MICROCHIP’S NEW POWER-MONITORING IC MEASURES POWER WITH 99% ACCURACY

Microchip recently developed a precision power-and-energy-monitoring chip – PAC1934. The PAC1934 is a four channel power/energy monitor with current sensor amplifier and bus voltage monitors that feed high-resolution ADC. It works in conjunction with a Microchip software driver that is fully compatible with the Energy Estimation Engine (E3) built into the Windows 10 operating system. The whole setup provide ...

INSIDE INTEL’S FIRST PRODUCT: THE 3101 RAM CHIP HELD JUST 64 BITS

Intel's first product was not a processor, but a memory chip: the 31011 RAM chip, released in April 1969. This chip held just 64 bits of data (equivalent to 8 letters or 16 digits) and had the steep price tag of $99.50.2 The chip's capacity was way too small to replace core memory, the dominant storage technology at the time, which stored bits in tiny magnetized ferrite cores. However, the 3101 performed at ...

Inside the vintage 74181 ALU chip: how it works and why it’s so strange

The 74181 ALU (arithmetic/logic unit) chip powered many of the minicomputers of the 1970s: it provided fast 4-bit arithmetic and logic functions, and could be combined to handle larger words, making it a key part of many CPUs. But if you look at the chip more closely, there are a few mysteries. It implements addition, subtraction, and the Boolean functions you'd expect, but why does it provide several bizar ...

One-chip 11×10 LED matrix. using pic microcontroller

This project is pretty cool for a few reasons, and driving a huge LED matrix with a single 8-bit controller is just one of them. The idea was born when I bought 120 LEDs of the wrong type, and decided to do something with them. With that many LEDs, there are only a few things you can do, and a matrix is the natural first-place-winner in the competition of those ideas. One of the LEDs did not work, so a 12x1 ...

LT puts supercapacitor power back-up on a chip

Linear Technology has put the whole of a supercapacitor power back-up system on one chip. Rated at 2A, it will back-up a voltage rail (Vsys) between 1.71 and 5.25V. Key to the chip, called LTC3110, is a 1.2MHz four-switch bi-directional dc-dc converter that both charges the capacitor and can also extract almost all of the energy remaining in it – as it keeps on switching until the capacitor has only 100mV l ...

Reverse engineering the popular 555 timer chip (CMOS version)

This article explains how the LMC555 timer chip works, from the tiny transistors and resistors on the silicon chip, to the functional units such as comparators and current mirrors that make it work. The popular 555 timer integrated circuit is said to be the world's best-selling integrated circuit with billions sold since it was designed in 1970 by analog IC wizard Hans Camenzind[1]. The LMC555 is a low-powe ...
