Several operations have been added to the 14-bit PICmicro repertoire: Rotate one bit left and right without carry, Set operand to all-ones, Skip if operand is zero (without incrementing or decrementing it first), Skip if operand is non-zero (some models), Add and subtract with carry, Decimal adjust after addition, for binary-coded decimal ...
In a binary search tree, a right rotation is the movement of a node, X, down to the right.This rotation assumes that X has a left child (or subtree). X's left child, R, becomes X's parent node and R's right child becomes X's new left child.
While what these instructions do is similar to bit level gather-scatter SIMD instructions, PDEP and PEXT instructions (like the rest of the BMI instruction sets) operate on general-purpose registers. [12] The instructions are available in 32-bit and 64-bit versions. An example using arbitrary source and selector in 32-bit mode is:
Rotate right by immediate without affecting flags. SARX ra,r/m,rb: VEX.LZ.F3.0F38 F7 /r: Arithmetic shift right without updating flags. For SARX, SHRX and SHLX, the shift-amount specified in rb is masked to 5 bits for 32-bit operand size and 6 bits for 64-bit operand size. SHRX ra,r/m,rb: VEX.LZ.F2.0F38 F7 /r: Logical shift right without ...
ANL C, bit, ANL C, / bit: And the bit (or its complement) to the carry bit A bit operand is written in the form address.number . Because the carry flag is bit 7 of the bit-addressable program status word, the SETB C , CLR C and CPL C instructions are shorter equivalents to SETB PSW.7 , CLR PSW.7 and CPL PSW.7 .
RISC-V assembly language is a low-level programming language that are used to produce object code for the RISC-V class of processors. Assembly languages are closely tied to the architecture's machine code instructions, allowing for precise control over hardware. Assemblers include GNU Assembler and LLVM.
The wider than 128-bit variations of the instruction perform the same operation on each 128-bit portion of input registers, but they do not extend it to select quadwords from different 128-bit fields (the meaning of imm8 operand is the same: either low or high quadword of the 128-bit field is selected).
The result should be 510 which is the 9-bit value 111111110 in binary. The 8 least significant bits always stored in the register would be 11111110 binary (254 decimal) but since there is carry out of bit 7 (the eight bit), the carry is set, indicating that the result needs 9 bits. The valid 9-bit result is the concatenation of the carry flag ...
