WebThe processor does not stall during bit-band operations unless it attempts to access the System bus while the bit-band operation is being carried out. The memory map has two 32MB alias regions that map to two 1MB bit-band regions: Accesses to the 32MB SRAM alias region map to the 1MB SRAM bit-band region.

WebThis is called 'mapping' and the bit-band address region is called an 'alias'. 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. WebAlso, reading a word in the alias region will return the value of the corresponding bit in the Bit-band region. These operations take a single machine instruction thus eliminate race …

Webnumber. Returns the number x rotated disp bits to the right. The number disp may be any representable integer. For any valid displacement, the following identity holds: assert(bit32.rrotate (x, disp) == bit32.rrotate (x , disp % 32)) In particular, negative displacements rotate to the left.
