warm greetings, I would want to know how capable is ARM M4 in handling up to 4 channel audio mixing of 24bits 44khz audio.
Audio fetching will be from Sd card system with FAT32 FS, QSPI to have high speed fetch. and once the audio is mixed it will stream…
I am using the Cortex M4 with CMSIS 5.4.0 DSP library. I'm using the arm_rfft_f32() function and the max_arm_f32() function to compute the maximum frequency bin of injected pure sine wave with an external CODEC. SSI0 and uDMA are being used to take in…
Hi.
I'm a robot engineer and I usually use MCUs such as nrf52832(cortex-M4f) or ST32f407(cortex) to use various sensors.
Since those MCUs have an FPU inside, calculating time was quite fast without any burdensome optimizations.
The problem is, I have to…
Hi to you all,
In my current project I need to send over a serial bus an array of integers:
The driver I'm using (actually USB CDC VCOM from NXP, which is embedded in LPCOpen) takes pointer to unit8 and…
I’ve been interning at ARM for the last two months as a summer student and spent a fair amount of time looking into the Digital Signal Processing (DSP) market and how it relates to ARM. DSP is used in speech recognition, radar signal analysis,…
The subject of digital filtering is vast but the basics can be understood easily. Digital filters process signals in the frequency domain and are commonly used to process sampled analog sensor data, images, video, audio and…
The Smart Home market is now at an inflection point. Early devices in the market were connected to the internet but were typically single-function, often lacking connectivity to other devices and with closed APIs, denying the user the ability to design…
Have you ever been in a situation where you successfully validated your algorithm and asked yourself: is there a hardware platform with DSP capabilities so I can get my embedded project to market quickly? Guess what: other people have dealt with the…
