DAISY / 390 : Full System Binary Translation of IBM System / 390

چکیده
We describe the design issues in an implementation of the ESA/390 architecture based on binary translation to a very long instruction word (VLIW) processor. During binary translation, complex ESA/390 instructions are decomposed into instruction \primitives" which are then scheduled onto a wide-issue machine. The aim is to achieve high instruction level parallelism due to the increased scheduling and optimization opportunities which can be exploited by binary translation software, combined with the e ciency of long instruction word architectures. A further aim is to study the feasibility of a common execution platform for di erent instruction set architectures, such as ESA/390, RS/6000, AS/400 and the Java Virtual Machine, so that multiple systems can be built around a common execution platform.

Architecture and software support in IBM S/390 Parallel Enterprise Servers for IEEE Floating-Point arithmetic
IEEE Binary Floating-Point is an industrystandard architecture. The IBM System/360 hexadecimal floating-point architecture predates the IEEE standard and has been carried forward through the System/370 to current System/390 processors. The growing importance of industry standards and floatingpoint combined to produce a need for IEEE Floating-Point on System/390. At the same time, customer inves...

Scalability has never been more a part of System/390 than with Parallel Sysplex. The Parallel Sysplex environment permits a mainframe or Parallel Enterprise Server to grow from a single system to a configuration of 32 systems (initially), and appear as a single image to the end user and applications. The IBM S/390 Parallel Sysplex provides capacity for today’s largest commercial workloads by en...

As the Internet becomes the basis for electronic commerce, and as more businesses automate their data processing operations, the potential for unauthorized disclosure of sensitive data increases. On-line databases are becoming increasingly large and complex. Sensitive data is transmitted on communication lines and often stored off-line. As a result, the efficient, economical protection of enter...
متن کامل— G 5 and G 6 performance considerations
The CMOS-based IBM S/390 Parallel Enterprise Servers have always employed the technique of memory caching to bridge the gap between processor speed and mainmemory access time. However, that gap has widened with each succeeding system generation, requiring increasingly sophisticated, multiple-level cache structures in order to minimize memory-access latency. The IBM S/390 G5 and G6 include two-l...
