point operations. This is expected to be particularly useful for the calculations involved in many fi nancial transactions.

Decimal calculations are often used in fi nancial applica- tions and those done using other fl oating point facilities have typically been performed by software through the use of libraries. With a hardware decimal fl oating point unit, some of these calculations may be done directly and accelerated.

Liberating your assets with System z

Enterprises have millions of dollars worth of mainframe assets and core business applications that support the heart of the business. The convergence of service oriented architecture (SOA) and mainframe technologies can help liberate these core business assets by making it easier

to enrich, modernize, extend and reuse them well beyond their original scope of design. The z10 EC, along with the inherent strengths and capabilities of a z/OS environment, provides an excellent platform for being an enterprise hub. Innovative System z software solutions from WebSphere®, CICS®, Rational® and Lotus® strengthen the fl exibility of

doing SOA.

Evolving for your business

The z10 EC is the next step in the evolution of the System z mainframe, fulfi lling our promise to deliver technol- ogy improvements in areas that the mainframe excels in—energy effi ciency, scalability, virtualization, security and availability. The redesigned processor chip helps the z10 EC make high performance compute-intensive processing a reality. Flexibility and control over capacity gives IT the upper edge over planned or unforeseen demands. And new technologies can benefi t from the inherit strengths of the mainframe. This evolving technology delivers a compel- ling case for the future to run on System z.

The z10 EC continues the line of upward compatible main- frame processors and retains application compatibility since 1964. The z10 EC supports all z/Architecture-compli- ant Operating Systems. The heart of the processor unit is the Enterprise Quad Core z10 Processor Unit chip which is specifi cally designed and optimized for mainframe sys- tems. New features enhance enterprise data serving per- formance as well as CPU-intensive workloads.

The z10 EC, like its predecessors, supports 24-, 31-, and 64-bit addressing, as well as multiple arithmetic formats. High-performance logical partitioning via Processor Resource/Systems Manager™ (PR/SM™) is achieved by industry-leading virtualization support provided by z/VM.

z10 EC Architecture

Rich CISC Instruction Set Architecture (ISA)

•894 instructions (668 implemented entirely in hardware)

•Multiple address spaces robust inter-process security

•Multiple arithmetic formats

Architectural extensions for z10 EC

•50+ instructions added to z10 EC to improve compiled code effi ciency

z/Architecture operating system support

Delivering the technologies required to address today’s IT challenges also takes much more than just a server; it requires all of the system elements to be working together.

IBM system z10 operating systems and servers are designed with a collaborative approach to exploit each other’s strengths.
