Jul 01, 2017 · Embodiments detailed herein relate to matrix operations. In particular, tile diagonal support is described. For example, a processor is detailed having decode circuitry to decode an instruction having fields for an opcode, a source operand identifier, and a destination matrix operand identifier; and execution circuitry to execute the decoded instruction to write the identified source operand ...

The difficulty arises from an earlier observation that ARM documents the NOP instruction as being usable only for alignment, and makes no promises about how it impacts execution time. In fact, ARM specifies that its use may decrease execution time, miraculous though that might be.

All ARM processors implement the undefined instruction space as one of the entry mechanisms for the Undefined Instruction Exception. That is, ARM instructions with opcode[27:25] = 0b011 and opcode = 1 are UNDEFINED on all ARM processors including the ARM9TDMI and ARM7TDMI.

Jan 12, 2014 · Here's the bit layout of an ARM data processing instruction: Any instruction with bits 27 and 26 as 00 is data processing. The four-bit opcode field in bits 24–21 defines exactly which instruction this is: add, subtract, move, compare, and so on. 0100 is ADD. Bit 25 is the "immediate" bit. If it's 0, then operand 2 is a register.
The malicious samples in our dataset were designed for eight ISAs: x86, x64, MIPS, ARM, SPARC, PowerPC, Renesas SH, and Motorola m68k. Each ISA has specific opcodes, but some with different spellings have similar functions.
