In a logical shift instruction (also referred to as unsigned shift ), the bits that slide off the end disappear (except for the last, which goes into the carry flag), and the spaces are always filled with zeros. Logical shifts are best used with unsigned numbers. shr cnt, dest. GAS Syntax. shr dest, cnt. Intel Syntax.

Rotate With Carry Left (rcl) - Oracle

WebRotate Carry Left The Instruction RCL (Rotate through Carry Left) shifts the bits of the destination to the left. The msb is shifted Into the CF, and the previous value of CF is shifted Into the rightmost bit. RCL works like just like ROL, except that CF is part of the circle of bits being rotated. The syntax is similar to ROL.

WebRCR InstructionThe RCR (rotate carry right) instruction shifts each bit to the right, copies the Carry flag into the MSB, and copies the LSB into the Carry f... WebThe carry flag (CF) is included in the rotation. The most significant bit is rotated to the carry flag, the carry flag is rotated to the least significant bit position, all other bits are shifted to the left. The result includes the original value of the carry flag. The first operand value indicates how many times the rotate takes place. original babycham glasses

Did you know?

WebThe rcr (rotate through carry right) instruction is the complement to the rcl instruction. It shifts its bits right through the carry flag and back into the H.O. bit: This instruction sets the flags in a manner analogous to rcl: The carry flag contains the last bit shifted out of the L.O. bit of the operand. WebMay 16, 2011 · after rotation values: byte A 10011000 byte B 00000001 <<< this is the carry bit put into this variable In variable A, the top bit, b7, is first tested to see if it is set by masking it with 0x80 to isolate that bit (this top bit is the one which will drop out into the carry when that byte is rotated.)

WebAnother example may be an 8-bit register with the bit pattern 01010101 and the carry flag set; if we execute a rotate left through carry instruction, the result would be 10101011 with the carry flag cleared because the most significant bit (bit 7) was rotated into the carry while the carry was rotated into the least significant bit (bit 0). Web41. ROL and ROR, Rotate Without Carry <<< Rotate Instructions Index : RCL and RCR, Rotate With Carry ...

WebIt will turn out that it is often more convenient for the rotate operation to shift the output bit through the carry and shift the previous carry value back into the input bit of the shift operation. The 80x86 rcl (rotate through, carry left) and rcr (rotate through, carry right) instructions achieve this for you.

WebThe RCR (rotate carry right) instruction shifts each bit to the right, copies the Carry flag into the MSB, and copies the LSB into the Carry flag.
