WebConsistent semantics across 16, 32 and 64 bit platforms. Supports different lua_Number types: either IEEE 754 doubles, int32_t or int64_t. Runs on Linux, *BSD, Mac OS X, Windows and probably anything else you can find. WebThere are at least two very different reasons for bitwise operations: (1) set operations on a small universe of members and (2) manipulation of fields in explicit representations of data defined externally to the Lua program. The referenced implementations of bitwise operators are designed primarily for the latter.

WebIf you need to do atomic operations (not necessarily limited to bit-band ones) on non-bit-band memory, you are forced to use 'other means' to achieve the atomicity. For example you could disable all interrupts*, do the operation and then restore interrupts. That's what I had to do when porting bit-band code to stm32f7. WebBit-band operations use ordinary load/store instructions to read and write single bits. In CM3, bit bands are implemented in two areas. One of them is the lowest 1MB range in the SRAM area, and the second is the lowest 1MB range in the on-chip peripheral area. In addition to the addresses in these two areas can be used like ordinary RAM, they ...

Seems strange, doesn't it. If the HSION bit is set, then its address in the bit-band region contains the value 0x00000001 (a 4-byte location for every aliased bit); if it is reset, then the corresponding value in the bit-band region is 0x00000000. graeter ice cream dog daysWeb6.7.4 Bit-band operations in C programs.
