Description: There is a group number 16, respectively Statistics negative, zero, positive number, and save the result number
area reset, data, readwrite
source dcb 1,2,5,-6,-5,3,0,7,-9,0,0,5,12,-94,-3,55
number dcb 0,0,0 were preserved statistics obtained negative, 0, the number of positive numbers
For data area 64 cumulative operating result
First memory unit of 100 words began to fill the memory address 0x3000 0x10000001 ~ 0x10000064 word data, and then each word unit 64 cumulative result is saved in [r9: r8] in (r9 stored in the high 32).
First through the loop on the memory unit assignment, then 100 words accumulate.
Seeking a number of factorial (64 results)
ARM assembly language programming seeking to achieve 20! (Factorial 20), and 64 results in [r9: r8] in (r9 stored in the high 32).
Design ideas: 64 results multiply instruction is multiplied by two 32-bit registers, you can get 64 results in multiplying each cycle, you c
