DSP, q31, q15, q7, f32, 定點數格式, 浮點數格式, Q格式 Why does DSP (Digital Signal Processing) need Q format? What do q31, q15, q7, and f32 mean? 1480414220013 In DSP operations, when a problem cannot be solved by using an integer, and the floating-point operation spends too much time, the Q format can be used to solve the problem regarding performance and operation time. q31, q15, and q7 use a fixed-point number to represent the bits of fractional part. The data size is 32, 16, and 8 bits respectively, and the values are in the range of -1 to 0.9999. f32 is the floating-point number that uses 32 bits to store and represent. Example: The hexadecimal number 0x2000 = 8192, but in the q15 format is 0.25, the reason is that 0x2000 expands into the binary number 0010 0000 0000 0000, and then includes 15 fractional bits, i.e. 0.010 0000 0000 0000 is equal to 0.25 of the 10's carry (the first digit of the left is the number of symbols). In addition, after the multiplication of Q format, it needs to be

What is the operating voltage for ADC converter? 1423030249301 In the NuMicro™ family, the power distribution is divided into three segments: 1. Analog power from AVDD and AVSS provides the power for analog components operation; 2. Digital power from VDD and VSS supplies the power to the internal regulator with a fixed 1.8 V power for digital operation and I/O pins. (Except NUC100/120 AN, NUC100/120 BN and NUC130/140 CN and M051 AN Series will be 2.5V.) 3. USB transceiver power from VBUS offers the power for operating the USB transceiver (for NuMicro™ USB Series only). The operating voltage for ADC converter is 0 ~ VREF. Analog power (AVDD) should be the same voltage level of the digital power (VDD), otherwise the leakage occurs. Below figure is an example for the power architecture of NUC122 Series.

Finanzen / Nuvoton Technology Holds Investor Conference for the first quarter of 2015.
https://www.nuvoton.com.cn/news/news/financial-information/TSNuvotonNews-000186/
Nuvoton Technology Corporation (TSE: 4919) and its parent company, Winbond Electronics Corporation (TSE: 2344), held a joint investor conference today (30) to announce operating results for the first quarter of 2015 and future prospects. The consolidated operating revenue in the first quarter of 2015 was about NT$ 1.632 billion and the gross margin rate reached 44.1%. Net income for the first quarter of 2015 was around NT$ 96 million and earnings per share of NT$ 0.46, an increase of 214% and 116% on QoQ and YoY basis respectively. The revenue in the first quarter of 2015, as compared to the fourth quarter of 2014, increased due to the growth of ARM® Cortex®- M0 32-bit MCU applying on ETC, model airplanes and personal healthcare devices; shipment of SIO/EC that supports Intel® and AMD New Generation Desktop/NB platform; and the fact that foundry customers preparing for peak season demands in the second quarter. The increase in the gross margin rate during the first quarter of 2015, as

What are the clock sources of Timer controller? Can user select the clock sources independently for each Timer controller? 1423561307684 The clock sources of Timer controller can be divided into internal and external sources of crystal and the number of the clock sources depends on each series of chips. The supported external clock sources include 4-24 MHz, 32.768 kHz, and GPIO. The supported internal clock sources include system clock HCLK and internal RC of 22.1184 MHz (or 12 MHz). User can select a different clock source for each Timer controller by setting the TMRx_S bit of CLKSEL1 register.
