-Tiling is an important program transformation that is used to improve data locality and parallelization granularity. ​+======Tiled Code Generator====== 
 +Tiling is an important program transformation that is used to improve data locality and parallelization granularity. We provide a tiled code generator that produces tiled code with wavefront parallelization supported for the shared memory machine.  
 + 
 +===Usage=== 
 +Let's use the classic matrix multiplication as an illustration example, whose alphabets code is the following:​ 
 +<sxh alphabets; gutter:​true>​ 
 +affine matrix_product {P, Q, R|P>0 && Q>0 && R>0} 
 +       ​given ​ float A {i,k| 0<​=i<​P && 0<​=k<​Q};​ 
 +              float B {k,j| 0<​=k<​Q && 0<​=j<​R};​  
 +     ​returns ​ float C {i,j,k| 0<​=i<​P && 0<​=j<​R && k==Q}; 
 +using 
 +   float temp_C {i,​j,​k|0<​=i<​P && 0<​=j<​R && 0<​=k<​=Q};​ 
 +through 
 +   ​temp_C[i,​j,​k] = case 
 +                      {|k>​0} ​ : temp_C[i,​j,​k-1] + A[i,​k-1]*B[k-1,​j];​ 
 +                      {|k==0} : 0;  
 +                   ​esac;​ 
 +   ​C ​     = temp_C; 
 +
 +</​sxh>​ 
 + 
 +The tiled code generator is called through ScheduledC, therefore, the first step for the code generation is the same with ScheduledC -- specify spacetime map and memory map
