CACHE MEMORY PRINCIPLES

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…

Setting up Keil for Your First LED Blinking Program on STM32F7 Discovery Board

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…

Find the Periodicity of Noisy Data using Autocorrelation method in MATLAB

Autocorrelation (short ACF, autocorrelation function) is a cross-correlation of a signal with itself. By correlating a signal with itself, repetitive patterns will stand out and make it much easier to see. The (discrete) autocorrelation of a signal x is defined by the following simple equation. The entire signal x is shifted by an offset j and then multiplied Read more…
