Description

 

 

Validation Description

This describes all possible ATCA-blade population profiles

 

for a particular product. The description explains the

 

inventory and legal combinations of hardware resources,

 

primarily those hosting one or more SAF AMF nodes.

 

Hardware resources are identified by HPI Entity Path names

 

with key 'identifier' attributes called out.

 

 

NCS Deployment description

This identifies the actual ATCA-blade configuration and NCS

 

Middleware deployed for this device in the network. For

 

example, it identifies the actual blade type expected in a slot

 

from among the 'valid blades' expressed in the Validation

 

Description. This Description also identifies which NCS

 

middleware pieces live where (which blade) and the

 

redundancy models used by those NCS middleware pieces

 

(since the NCS Middleware is itself HA).

 

This portion of the description will likely require some

 

adjusting at deployment time. This depends on how many

 

plausible (and used) configurations there are for a particular

 

product,

 

 

Customer deployment description

This identifies how customer application SW is distributed

 

(deployed) for this device in the network. Just as with the

 

NCS Middleware, this description identifies which application

 

sub-parts live where (which AMF node) and the redundancy

 

models used by those application sub-parts (as it is generally

 

expected that customer applications shall be HA).

2.4Management Access

NCS provides two ways to access the Avantellis system for managent purposes: via CLI interface and via SNMP.

Both management access points resolve to a common managed object definition. This common definition allows the system managed objects to be distributed throughout the NCS services. These objects may be owned (implemented) by NCS, PCS and user applications as long as they have been properly integrated with the NCS Management Access Service (MASv). All NCS configuration parameters are managed by this service.

The flow is roughly as follows:

1.A MASv client, such as a CLI or SNMP Agent, translates a transaction request to a MASv format

2.The MASv client then initiates a transaction via the Management Access Agent (MAA) API library, which always forwards the transaction to the Management Access Server (MAS), where a repository of object locations is maintained.

6806800C08B specifications

The Motorola 68000 microprocessor, particularly the revision marked as 68000C08B, stands out as a seminal component in the evolution of computing technology. Introduced in 1979, the 68000 architecture laid the groundwork for many advanced systems, influencing a multitude of platforms, from personal computers to game consoles.

The Motorola 68000C08B features a 16-bit data bus and a 24-bit address bus, allowing for a memory addressing capability of up to 16 MB. This architecture was pioneering for its time, enabling more extensive and complex software applications than its predecessors. The C08 revision particularly emphasized optimizing power consumption while maintaining performance, making it ideal for embedded systems and portable devices.

One of the 68000's key characteristics is its unique register set, which allows for a versatile range of operations. It consists of 8 general-purpose data registers and 8 address registers. The architecture supports both integer and floating-point operations, thanks to an integrated instruction set that facilitates complex mathematical computations, crucial for applications in graphics and gaming.

In terms of performance, the 68000 processor operates at clock speeds ranging from 8 MHz to 16 MHz, depending on the specific variant. The instruction set architecture (ISA) is known for its orthogonality, meaning that most instructions can be used interchangeably across different registers. This design simplicity allows for efficient coding and faster execution times, a significant advantage for developers.

Another remarkable feature of the 68000C08B is its capability for multitasking and improved context switching. Its advanced memory management, combined with support for virtual memory in later implementations, catered to the needs of operating systems and real-time applications, making it suitable for both consumer electronics and industrial machinery.

The Motorola 68000 family also supports a variety of peripherals, enhancing its flexibility as a microcontroller. This compatibility allowed manufacturers to create diverse product lines, from keypads and mice to modems and hard drives.

In summary, the Motorola 68000C08B microprocessor not only advanced the landscape of computer technology in the late 20th century but also helped set the stage for future innovations through its architecture, performance capabilities, and versatility in numerous applications. Its legacy continues to influence modern computing paradigms, ensuring the 68000 remains an essential chapter in the history of microprocessors.
