How many registers are there in ARM7?(a) 35 register( 28 GPR and 7 SPR)(b) 37 registers(28 GPR and 9 SPR)(c) 37 registers(31 GPR and 6 SPR)(d) 35 register(30 GPR and 5 SPR)I had been asked this question in final exam.I need to ask this question from Microcontroller (ARM 7) in section Prototyping Embedded Devices of IOT

Answer»

Correct ANSWER is (c) 37 REGISTERS(31 GPR and 6 SPR)

The EXPLANATION: ARM7TDMI has 37 registers(31 GPR and 6 SPR). All these designs use a Von Neumann ARCHITECTURE, thus the few versions comprising a cache do not SEPARATE data and instruction caches.
