MIPS Assembly Language (Power2) -

-

i looking best method performing n power2 function. in short, code in mips should calculate 2n. n being positive number stored in $a0. however, of right results coming 1 power less.

my attempt

main:      # initialize      la  $a0,3       #n counter     li  $s0,2       #base number     li  $s1,0       #calculated value  while:       beq $a0,$zero,exit      #checks if n zero, if yes exit program      sllv $s1,$s0,$a0        #shift left logical n, should math 2^n  exit:

results qtspim

"failed" isn't informative statement. anyway, correct syntax beg $a0,$zero,j exit beq $a0, $zero, exit don't need check. should load $s0 1 not 0 since 2^0 1 , sll $s0, 2, $a0 should sllv $s0, $s0, $a0.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i

Sass watch command compiles .scss files before full sftp upload -
