IEEE 1800-2017, 11.4.10 Shift operators specifies:The arithmetic right shift shall fill the vacated bit positions with zeros if the result type is unsigned. It shall fill the vacated bit positions with the value of the most significant (i.e., sign) bit of the...

Beware of shift operations, which can produce a result wider than the operand. Bit-selection and concatenation may be clearer than shifting by a constant amount. Addition and negation operations produce a result one bit wider than the operands, due to carry. An allowable exception to the rule ...
53、grees to -90 degrees.3.3 Log - ShifterThe shifter used is a Log Shifter that shifts a 12 bit number c_in arithmetically by k bits to theright. It uses the comb in ati on of 3 modules, n amely sin gle, double, triple that respectively shift the number by 2A0 = , 2A1 = ...
! (not) Binary && (and) || (or) Shifting There are logical and arithmetic shift. Arithmetic right shift fills the additional bits with 1 if the number was singed and first bit was 1, whereas logical shift will always fill them with 0. Binary << shift_amnt Logical left shift >> ...
(shifting left by n corresponds to multiplication by 2^n, shifting right by n corresponds to division by 2^n). If you're working with a large filter with many taps, and can't make them all into powers of 2, you might be better off using a system clock that runs (much) faster ...
If the value stored in register address Rs2 is equivalent to 0, the bits will logically shift left, otherwise, the bits will arithmetically shift right. Optionally, adding an "s" to the end of the opcode identifier will tell the processor to set the condition codes as a result of the ...
