Can someone suggest a microcontroller platform that has a built in floating-point-unit? Preferably small, inexpensive and easy to work with, well supported, plenty of libraries I'm working on an astrolabe and there is a ton of floating point math involved calculating the positions of celestial objects. A microcontroller at 16 MHz or 48MHz is not even near a normal computer. The microcontrollers are cheap and simple and don't have a FPU.

Floating Point Unit support Arduino Zero.

Would you bet on it? One of the problems we have in the electronics and computing industries is a surfeit of TLAs three letter acronyms. The fact that the same TLA can be used to represent multiple and diverse things only exacerbates the matter. I just had a quick Google while no one was looking. I was trying to track a saying down. Instead, I ended up falling down a Google rabbit hole with topics like:.

Espressif Systems SSE: ESPP4 is designed for high-performance applications that require strong security. In fact, ESPP4 aims to cater to the next era of embedded applications which will rely on solid support for rich Human-Machine Interfaces, efficient edge computing, and increased IO-connectivity requirements. This is critical in terms of supporting ultra-low-power applications which may occasionally require high computing. In such scenarios, the HP cores can be kept down for most of the time, for the purpose of saving power. This high-performance memory system, along with the support for external PSRAM and Flash, ensures that the memory-access latency and the available size of memory are not limited. Strong security is at the heart of ESPP4.

Double precision is very rare in this class some M7 have one , and the single-precision FPU of the M4 is definitely less accurate than fixed-point implementations. Overview of Dev Environment. As one famous SW guru said: "Premature optimization is the root of all evil. There was some proprietary information that could not be shared. This thread has been locked. I hear that some of the popular Unix implementations for these don't support Floating point HW don't provide libraries that use it, don't save the CPU context in task switching, etc. DrWizard: Can someone suggest a microcontroller platform that has a built in floating-point-unit? Also, I don't know if this is the right forum for this Hence, a private message was sent via email and the feedback will be shared in this post. Many MCUs only support bit external interfaces with wait states , which is probably detrimental to performance requirements. I don't think it's gonna solve this problem for me, but a good thing to have in my toolbox. Floating Point Unit support Arduino Zero. Team may benefit from some attention to detail

Up 0 True Down Cancel. But, maybe not. I've found a number of different chips that include FPUs, but haven't been able to find any boards featuring those chips, other than the Tiva C. The only one found is an m7 core which is very power hungry. As one famous SW guru said: "Premature optimization is the root of all evil. Similar topics. When talking astronomy you definitely need double precision FPU 64bit. It's just not a popular or well supported platform, and I've had only limited success at porting libraries from other platforms to it. A related question is a question created from another question. Arm-based microcontrollers Arm-based microcontrollers forum. Before going down the rabbit hole, you may wish to do some research to determine what code changes and syntax are required to support the hardware FPU. Site Search User.
