@ -4,7 +4,7 @@ MicroPython is named "Micro" for a reason. We don't want to compete with CPython
Here are more specific examples:
1. For a microcontroller case, the reference MicroPython implementation runs on a pretty big MCU. But we would like to maintain portability to much smaller MCU cores. The theorhetical minimum requirements we'd like to maintain are 128K ROM/8K RAM. Note that those are "raw hardware" requirements. In real-world case, part of ROM and RAM may be used for RTOS/supervisor, and that lowers requirements to around 100K/4K respectively.

2. It may seem that the "unix" port would not be affected by such stringent requirements, and yet it is, because one of the usecases is running MicroPython on truly minimal Linux systems with just 4 or even 2Mb of flash, half of which is taken by the kernel, remaining half by support utilities, and only mere hundreds of Ks are available for MicroPython, user apps, and data. So, every byte is still accounted for.
