and statistics on indirect benefits of informatization by foreign research institutions. In addition, due to the short start of large-scale informatization work in China, there is a lack of economic research on Informatization and there is not enough theory and data, representative results published by foreign research institutions can also be studied and studied. The evaluation conclusions of the three foreign companies are selected below. A. benchmarkingpartners, an internationally renowned

advanced programmable controller (APIC) to replace the legacy 8259a Programmable Interrupt Controller. First, the new system retains the two cascading vintage PIC 8259a to support older operating systems. Second, the new 80 x CPU control units all contain a local APIC. This is not surprising, in order to support multi-CPU or multi-core systems. Each local APIC has a 32-bit register, an internal clock, a local scheduled device, and two additional IRQ lines lint0 and lint1 reserved for local APIC

the local APIC when those devices need to be interrupted, the system can have up to 8 I/O APIC. Each local APIC has a 32-bit register, an internal clock, a local scheduled device, and two additional IRQ lines LINT0 and LINT1 reserved for local interruptions. All local apics are connected to I/O APIC to form a multi-level APIC system, as shown in figure 2.Figure 2: Multi-Level I/O APIC System Currently, most single-processor systems contain an I/O API

ERP starts from implementing internal integration, which is a practical step from simple to deep, from internal to external. That is, internal integration is a solid and necessary process.This book attempts to find the root, trace the source, and be fair and pragmatic. According to the research report of Gartner Group, which first proposed the concept of ERP, we will introduce ERP: According to the classic literature of the American production and Inventory Management Association (

inventory, and improve production efficiency. Material Requirement information consists of the following four elements:● What is needed;● When required;● Required;● When to order. The requirement information, product structure, collection and supply lead time, and inventory information of materials are the four main data for running MRP. The accuracy of the data determines the effectiveness of MRP. The American Association for production and inventory control (

the needs of this competitive situation. -The American Association for production and inventory management (APICS), known for its integrated management technology and information technology, will be qualified for production and inventory management (CPIM) from January 1, 1997) the supply chain management is added to the examination and listed as the first among the seven topics (the remaining topics are inventory management, JIT, main plan, material

refers to the ability of the operating system to allow different CPUs to perform different tasks at the same time; multithreading means that the operating system enables different CPUs to accomplish the same task in parallel.　　To build an SMP system, there is a high demand for the selected CPU, first of all, the internal APIC must be built into the CPU (advancedProgrammable Interrupt Controllers) unit. IntelThe core of the multi-processing specification is the Advanced Programmable Interrupt Co

not support multiple CPUs, the direct effect of APIC shutdown is to reduce the available IRQ.However, if the board is not very much, shutting down the APIC has no effect on the system.To implement the SMP feature, the CPU we use must have the following requirements:The APIC unit must be built inside the CPU. The core of the Intel Multi-processing specification is the use of Advanced Programmable Interrupt controllers (Programmable Interrupt controllers--api
