They already have an ARM license and the vast majority of ARM processors in existence are Cortex-M class microprocessors (i.e ARM pretty much owns the target market for RISC-V at the moment). This means they're not looking at RISC-V fo

I would narrow that recommendation to just BuildRoot TBH. It fits much more with the kernel-config style whereas Yocto config seems like its from another planet. BuildRoot is much easier to work with IMO and gives equivalent or better resul

The TMS320C6678 (C66x architecture) DSPs still use VLIW and work pretty well. Like most DSPs, they're typically programmed using C, for which TI supplies optimised libraries for processor-intensive operations. IIRC, the compiler itsel

Are you confusing NTFS with FAT32? NTFS is pretty much limited to internal drives on Windows PCs.

Compatibility with the rest of the ARM development & tooling world is one fairly large reason to stick with the original ARM64 ABI. I would imagine, for example that GCC would not now work for ARM64EC and therefore you're getting l

Occam was designed for the Transputer, which was intended to be used in arrays of processors, hence it being based on CSP principles. So, yes. it can.

The Lua interpreter is not a real-time interpreter and cannot give bounded response time. This is a non-realtime application running on top of a scheduler that is capable of supporting realtime applications. Just placing an application on t

Its quite common to use "while(true);" in the embedded world in order to trigger the hardware watchdog and cause a reset in a panic situation. It indicates that the only sensible option is to reset the processor to get back to a k

CAN is intended for real-time applications, i.e. with bounded latency. Its also intended for use in noisy environments, hence the differential signalling. Both these characteristics are required for automotive applications. I2C is relativel

I work on mesh networks for the smart utilities (think smart metering in India). Our deployments are in the hundreds of thousands and individual meshes of up to 1000 nodes. We use similar technologies to described in the article (802.15.4,

non-x86 is emulated and bare-metal limits the portability.

by TickleSteve 6y ago
Its not the difficulty, but the scale. Working on one bare metal system is relatively easy as long as you're willing to dive into drivers. Getting 1001 I2C drivers or maybe writing a drivers for tens of different types of flash devices

Sorry, wasn't meant as a criticism, just as an explanation because people were assuming magic... Taking on bare-metal is a significant job much greater than your original task and you may be better targeting something like buildroot in

TLDR: This is a packed file format that can look to the OS as being executable (for Windows/Linux/OSX). The code is x86 and so offers native performance on those processors. On other platforms, an x86 emulator is built in so can&#

I remember the Osbornes, I had one for a few months when I was a kid. IIRC they had parallel ports on the front that you can use as GPIOs if you fancy flashing a few LEDs or controlling relays. There was also a dBase implementation for it.

You can do bare-metal on the RPi also, you don't have to use a (non-realtime) OS like Linux which is where your latency issues come from. You can treat the RPi as a microcontroller and program it via JTAG, etc if you like. Latency issu

Compare the overheads and failure modes of a request to that of a method call, thats the comparison. Requests can fail in a host of ways that a call simply cannot, the complexity is massively greater than a method call.

TAOS also ran on many other architectures (68K, x86, ARM). It implemented a virtual processor (VP1) and evolved into Elate but didn't get much recognition despite its novelty. TAOS was definitely ahead of its time, but rarely gets ment

What you're really asking is if this supports the neural engine? GPU support is of course 'native' to the M1 also and seems to be the limit of the support here. Neural engine support is not stated.
