The term Computer Architecture was first defined in the paper by Amdahl, Blaauw and Brooks of International Business Machines (IBM) Corporation … Webbcial purpose instructions are not always faster than a sequence of simple instructions. One example was discovered by Peuto and Shustek for the IBM 370 [Peuto,Shustek77]; they found that a sequence of load instructions is faster than a load multiple instruction for fewer than 4 registers.

WebbThere are two GNU assemblers that understand the the 360/370/390 instruction set. These are the 's390' and the 'i370' assembler front-ends in the gnu 'binutils' package. Neither are HLASM-compatible, although the i370 assembler is closer to HLASM, primarily because it supports literal pools, and uses an HLASM-like syntax for instruction … WebbThe higher number (on the left side of "/") means duration of instruction when action is taken, the lower number (on the right side of "/") means duration of instruction when action is not taken. All instructions marked by "*" are only alternative opcodes for existing instructions. Those alternative opcodes should not be used.
