## Keil C51 right shift for 16 bit int

mydata=0x8000; mydata>>=1; Now, mydata becomes 0xC000; That's the expectable result if mydata is signed int (arithmetic shift). You may want to use an unsigned int data type.

## SINE and COSINE calculations using COiRDIC Algorithm

You need to review the available functions of the used libraries. For STD_LOGIC_ARITH SHR() performs an arithmetic right shift of signed signals. I don't follow your statement about complexity caused by the delta() function. It's not much different from a SHR() or SRA() implementation in other libraries. A fixed shift (...)

## Verilog arithmetic shift weird behavior

Actually, in first case three times right shift of -27 is calculated which is -4(9'b000111100) and is stored in register of signed type, so it is stored as -4. Then it is added with x0 (which is 1) and becomes -3. But in second case, after the calculation of three right shifts of -27, result is not stored in signed format (...)

## how to make three function parallel shifter in vhdl

I hope it can help Overview VHDL code

## SRA(shift right arithmetic)...?

Who can modify the HDL code for the single-cycle MIPS processor to handle SRA(shift right arithmetic)...?? ------------------------------------------------------------ -- mips.vhd -- and 30 May 2006 -- Single Cycle MIPS processor -----------------------------------------

## some verilog operations ??

This is explained better with an example: Logical shift: shift right number 1010 several times: 1) 0101 2) 0010 3) 0001 4) 0000 MSB is always filled with zero. arithmetic shift: shift right number 1010 several times: 1) 1101 2) 1110 3) 1111 4) 1111 (...)

## Floating Point Arithmetic in Hardware (Circuit)

Hi all, I am going to implement "Floating Point arithmetic" for my Prediction Circuit, but i have no idea how to represent this arithmetic in term of hardware. Basically, i know i need some kinda of shift register or ALU....For shift register. shift left means "x2" or "1/2" when rotate (...)

## convert code from verilog to vhdl

VHDL93 includes built-in shift operators: sll (shift left logical), srl (shift right logical), sla (shift left arithmetic), sra (shift right arithmetic) See SRL is what u require.. tut..

## How to write a delay program in VHDL?

Operator: sla shift left arithmetic operator. Example: Addr <= Addr sla 8; Operator: sll shift left logical operator. Example: Addr <= Addr sll 8; Operator: sra shift right arithmetic operator. Example: Addr <= Addr sra 8; Operator: srl shift (...)
