Cache memory is intended to give memory speed approaching that of the fastest memories available, and at the same time provide a large memory size at the price of less expensive types of semiconductor memories. The concept is illustrated in Figure (a) below. There is a relatively large and slow Read more…
The STM32F745xx and STM32F746xx devices are based on the high-performance ARM®Cortex®-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex®-M7 core features a single floating point unit (SFPU) precision which supports all ARM®single-precision data-processing instructions and data types. It also implements a full set of DSP instructions Read more…

STM32F7 Discovery Board have 3 ADC on board and each ADC is 12-bit ADC. The 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 19 multiplexed channels allowing it to measure signals from 16 external sources, two internal sources, and the VBAT channel. The A/D conversion of the channels Read more…
Today we present the first steps with the NUCLEO development boards, produced by STMicroelectronics, that can help us to move towards the ARM 32-bit world with simplicity and great performances , keeping a compatibility with Arduino expansion connectors so that we can use its commonly available shields. The success of Read more…
Q.1 What are the key properties of semiconductor memory? Ans: They exhibit two stable (or semistable) states, which can be used to represent binary 1 and 0; they are capable of being written into (at least once), to set the state; they are capable of being read to sense the state. Read more…
Q.1 What are the differences among sequential access, direct access, and random access? Ans: Sequential access: Memory is organized into units of data, called records. Access must be made in a specific linear sequence. Direct access: Individual blocks or records have a unique address based on physical location. Access is accomplished by direct Read more…
Q.1 What are general categories of functions are specified by computer instructions? Ans: Computer instructions specify four general categories, those are Processor-memory: Data may be transferred from processor to memory or from memory to processor. Processor-I/O: Data may be transferred to or from a peripheral device by transferring between the Read more…
Q. What is Embedded System? Ans: A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function. In many cases, embedded systems are part of a larger system or product, as in the case of an antilock braking system in a Read more…
British processor powerhouse ARM Holdings, launch a new, low-power operating system that will manage web-connected devices and appliances using chips based on the company’s 32-bit Cortex-M microcontrollers. ARM Processor Got new OS mbed. The operating system, called mbed OS, is meant to resolve productivity problems that arise from fragmentation—where different devices in the so-called “Internet of things” (IoT) market run on a hodgepodge of different protocols. ARM is looking to consolidate those devices under a single software layer that’s simple, secure, and free for all manufacturers to use.
ARM has introduced a new processor of cortex M series, and this time it is Cortex M7. The ARM M7 processor is the most recent and highest performance member of the energy-efficient Cortex-M processor family. ARM quotes “The versatility and new memory features of the Cortex-M7 enable more powerful, smarter and reliable microcontrollers that can be used across a multitude of embedded applications”
This board has ARM cortex M0+ core on board and Processor family is KL25 and silicon core family is MKL25Z128xxx4. for small application this board can be your best choice such as motor control, home automation system and audio music system. The Freescale Freedom development platform is Read more…
The Internet of Things (IoT) is the network of physical objects embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. Each thing is uniquely identifiable through its embedded computing system but is able to Read more…
