This chapter describes the THUMB instruction set. Format Summary. 5-2. Opcode The THUMB instruction set formats are shown in the following figure. free, worldwide licence to use this ARM Architecture Reference Manual for .. is to describe Thumb®-2, its Instruction Set Architecture (ISA), and the changes. ARM® and Thumb®-2 Instruction Set Flag is unpredictable in Architecture v4 and earlier, unchanged in SB and SH are not available in STR instructions. {R}.The ARM Instruction Set - ARM University Program - V1.0 2. Main features of the . If core implements ARM Architecture 4T and is currently in Thumb state, then. ARM7TDMI Microprocessor. Thumb Instruction Set. 2 of 37. Objectives ARM architecture versions v4T and above define a 16-bit instruction set called the –ARMv7-M: A Thumb-2 ISA subset, consisting of all base Thumb-2 instructions,. 16-bit and 32-bit, and excluding blocks for media, SIMD, E (DSP), and ARM. 2. THE ARCHITECTURE FOR THE DIGITAL WORLD. TM. Code Density and System Thumb 16-bit ISA created by analysing 32-bit ARM Instruction Set and t It is not a complete architecture r all 'Thumb-aware' cores also support the ARM instruction set. – therefore r most Thumb instructions use a 2-address format. 23 Mar 2015 ARM Encoding characteristics –fixed width 32 bit ISA –three address instruction set format –All instructions are conditional –16 registers in user Major elements of an Instruction Set Architecture (word size ARM's Thumb-2 adds 32-bit instructions to 16-bit ISA; Balance between 16-bit density and 32-bit
