Linked list is a common data structure used in many applications. For our purposes, this will excercise the memory units of the processor. In particular, usage of the list pointers to find and alter data. We are not using Malloc since some platforms do not support this library. Instead, the memory block being passed in is used to create a list, and the benchmark takes care not to add more items then can be accomodated by the memory block. The porting layer will make sure that we have a valid memory block. All operations are done in place, without using any extra memory. The list itself contains list pointers and pointers to data items. Data items contain the following: idx - An index that captures the initial order of the list. data - Variable data initialized based on the input parameters. The 16b are divided as follows: o Upper 8b are backup of original data. o Bit 7 indicates if the lower 7 bits are to be used as is or calculated. o Bits 0-2 indicate type of operation to perform to get a 7b value. o Bits 3-6 provide input for the operation. */ /* local functions */ list_head *core_list_find(list_head *list,list_data *info); list_head *core_list_reverse(list_head *list); list_head *core_list_remove(list_head *item); list_head *core_list_undo_remove(list_head *item_removed, list_head *item_modified); list_head *core_list_insert_new(list_head *insert_point , list_data *info, list_head **memblock, list_data **datablock , list_head *memblock_end, list_data *datablock_end); typedef ee_s32(*list_cmp)(list_data *a, list_data *b, core_results *res); list_head *core_list_mergesort(list_head *list, list_cmp cmp, core_results *res); ee_s16 calc_func(ee_s16 *pdata, core_results *res) { ee_s16 data=*pdata; ee_s16 retval; ee_u8 optype=(data>>7) & 1; /* bit 7 indicates if the function result has been cached */ if (optype) /* if cached, use cache */ return (data & 0x007f); else { /* otherwise calculate and cache the result */ ee_s16 flag=data & 0x7; /* bits 0-2 is type of function to perform */ ee_s16 dtype=((data>>3) & 0xf); /* bits 3-6 is specific data for the operation */ dtype |= dtype << 4; /* replicate the lower 4 bits to get an 8b value */ switch (flag) { case 0: if (dtype<0x22) /* set min period for bit corruption */ dtype=0x22; retval=core_bench_state(res->size,res->memblock[3],res->seed1,res->seed2,dtype,res->crc); if (res->crcstate==0) res->crcstate=retval; break; case 1: retval=core_bench_matrix(&(res->mat),dtype,res->crc); if (res->crcmatrix==0) res->crcmatrix=retval; break; default: retval=data; break; } res->crc=crcu16(retval,res->crc); retval &= 0x007f; *pdata = (data & 0xff00) | 0x0080 | retval; /* cache the result */ return retval; } } /* Function: cmp_complex Compare the data item in a list cell.
