12. THUMB Instruction set: REGISTERS: Set of registers consists of bank of 16 user registers R0-R15, each of 32-bit length, 16 bit Thumb code Instruction pipeline Thumb Decompressor ARM instruction Decoder MEMORY MEMORY SET OF REGISTERS
13. R0-R12 are general purpose registers, R13- stack pointer R14- link register R15- program counter In addition to the banks it consists of 32 bit wide register called “ current program status register(CPSR )” N,Z,C,V are the Conditional Code Flags For example: ARM Instruction THUMB Instruction ADD R0,R0,R1 ADD R0,R1 R0=R0+R1 M 0 M 1 M 2 M 3 T 4 F 5 I 6 V 28 C 29 Z 30 N 31
