USB海量存儲(chǔ)設(shè)備類規(guī)范包括四個(gè)獨(dú)立的子類規(guī)范:(ATA command的那個(gè)沒有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command Block ④USB Mass Stroage Class UFI Command Specification。 前兩個(gè)子規(guī)范定義了數(shù)據(jù)/命令/狀態(tài)在USB上的傳輸方法。 Bulk-Only傳輸規(guī)范僅僅使用Bulk端點(diǎn)傳送數(shù)據(jù)/命令/狀態(tài), CBI傳輸規(guī)范則使用Control/Bulk/Interrupt三種類型的端點(diǎn)進(jìn)行數(shù)據(jù)/命令/狀態(tài)傳送。 后兩個(gè)子規(guī)范定義了對(duì)存儲(chǔ)介質(zhì)的操作命令。 ATA 命令規(guī)范用于硬盤。 UFI命令規(guī)范是針對(duì)USB移動(dòng)存儲(chǔ)而制定的,實(shí)際上UFI命令格式是基于SFF-8070i和SCSI-2規(guī)范,總共定義了19個(gè)12字節(jié)長度的操作命令。

A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc

The Staged Event-Driven Architecture (SEDA) is a new design for building scalable Internet services. SEDA has three major goals: To support massive concurrency, on the order of tens of thousands of clients per node To exhibit robust performance under wide variations in load and, To simplify the design of complex Internet services. SEDA decomposes a complex, event-driven application into a set of stages connected by queues. This design avoids the high overhead associated with thread-based concurrency models, and decouples event and thread scheduling from application logic. SEDA enables services to be well-conditioned to load, preventing resources from being overcommitted when demand exceeds service capacity. Decomposing services into a set of stages also enables modularity and code reuse, as well as the development of debugging tools for complex event-driven applications.
