the alphabetic set (allowing the set to grow), and commen- surability with a 32/64-bit floating-point word and a 16- bit instruction field. Most important of these In more modern terms, we speak of the “Instruction Set Architecture”, or. ISA, of a family of The basic idea behind the IBM System/360 was a family of computers that shared the same 32–bit registers, numbered 0 through 15. These were characteristics of System/360 and its instruction set. 7094 Support Package for IBM System/360. Note that the number 4096 requires 32 bit positions. System/360 was designed for implementation over a wide cost and demonstrates that the decimal instruction set is a more direct route . one 32-bit word. CS 350. IBM. System 360/370/390. Section 3.2 CISC S/360. • Instruction set a UNION of instruction sets. – fixed-point binary (7090) . ALU: 32 bits wide. The 360/370 Instruction Set Architecture. The IBM System/360 is a 32-bit machine with byte addressability and support for a variety of data types: byte, halfword The launch of the System/360 family introduced IBM's Solid Logic Technology (SLT), a new technology that was the start of more powerful but smaller computers. The slowest System/360 model announced in 1964, the Model 30, could perform up to 34,500 instructions per second, with memory from 8 to 64 KB. The basic System/360 instruction set is still used in current IBM mainframe Alpha was one of the early 64 bit architectures but it dies quickly in Compaq handsThe System/360 architecture provides the following features: 16 32-bit general-purpose registers. 4 64-bit floating-point registers. 64-bit processor status register (PSW), which includes a 24-bit instruction address. 24-bit (16 MB) byte-addressable memory space. Big-endian byte/word order. When the System/360 (which will be abbreviated "360") was introduced in 1964, . 360 instructions are those which were part of the original IBM 360 mainframe 010E, SAM64, Set Addressing Mode (to 64 bits), E, Control Flow Instructions, Z.
