PocketARM

Pocket ARM — ARMv7 Simulator Carry a complete ARM assembly development environment in your pocket. Pocket ARM is a full ARMv7 UAL assembly simulator for iOS, designed for computer science students, embedded developers, and anyone who wants to understand how processors really work — one instruction at a time. Learn ARM Assembly the Right Way There's no better way to understand a processor than to watch it think. Pocket ARM lets you write ARM assembly, assemble it instantly, and step through execution instruction by instruction — watching registers change, flags flip, and memory update in real time. A Professional Toolset in Your Hand Full ARMv7 UAL assembler with label resolution and condition codes All 16 general-purpose registers (R0–R15) with SP, LR, and PC clearly labelled CPSR status register with live N, Z, C, V, I, F, and T flag display Hex memory viewer with Text, Data, and Stack segment views Breakpoints — tap any instruction in the disassembly to pause execution there Step, Step N, Run, and Stop controls Console output for SVC calls Built for iPad and iPhone On iPad, Pocket ARM presents a classic quad-pane layout — registers, source editor, disassembly, memory, and console all visible simultaneously, inspired by the legendary xspim MIPS simulator. On iPhone, the same power is one tab away. Supported Instructions MOV, ADD, SUB, MUL, AND, ORR, EOR, BIC, CMP, TST, LSL, LSR, ASR, LDR, STR, PUSH, POP, B, BL, BX, and the full set of ARM condition code suffixes — EQ, NE, LT, GT, LE, GE, and more. Who Is It For? Computer science and computer engineering students studying processor architecture Embedded developers wanting a quick sandbox for ARM logic Hobbyists and retro computing enthusiasts curious about how RISC processors work Anyone who has ever wondered what happens inside a chip
