5、word SMPTE (the Society of Motion Picture and Television Engineers) is an internationally-recognized standards developing organization. Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six continents. SMPTEs Engineering Documents, including St

6、andards, Recommended Practices and Engineering Guidelines, are prepared by SMPTEs Technology Committees. Participation in these Committees is open to all with a bona fide interest in their work. SMPTE cooperates closely with other standards-developing organizations, including ISO, IEC and ITU. SMPTE

7、 Engineering Documents are drafted in accordance with the rules given in Part XIII of its Administrative Practices. SMPTE Recommended Practice 2006 was prepared by Technology Committee V16. 1 Scope This document defines the specification of the Solid State Media (SSM) Card. The physical specificatio

8、n provides the physical characteristics of the Card and the connector. The electrical interface between a host and the Card is a high performance bus and this document specifies the signal description, the electrical characteristics, and the bus operations. The register specification defines the reg

9、isters for configuration and also defines the specific registers related to interrupt signals or commands. The command specification defines the commands for the bus master data transfer and the sensing log information written in the SSM Card in addition to the ATA commands. To guarantee the perform

10、ance of the SSM Card, requirements for writing and reading speed are specified. The file system for the SSM Card is the FAT system. 2 Normative references The following standards contain provisions, which, through reference in this text, constitute provisions of this standard.

Figure 4.1 Structure of SSM Card specification and relatio

24、n between Reference documents The physical specification defines the Card package dimensions, the Card connector, the write protect switch for protection of files stored on the SSM Card and the Card ID to identify the SSM Card. The electrical interface of the SSM Card is a high performance 32 bit bu

25、s with multiplexed address and data lines. This document specifies the signal descriptions, the electrical characteristics and the bus operations of this SSM Card. The register specification defines the Configuration space registers to identify or control the SSM Card and also defines the specific r

26、egisters related to interruption or commands. The command specifications define the commands required for the SSM Card. Write protection and power management are performed using ATA commands as unique functions for the SSM Card. Data transmission between a SSM Card and a host is performed using the

27、Bus Master DMA transfer commands. After a read or write command is issued from the host, the SSM Card takes initiative of bus control and performs data transfers as the bus master. Furthermore, the commands for sensing log information written in the SSM Card are specified. To guarantee the performan

28、ce of the SSM Card, the writing and reading speeds required for the SSM Card are specified. The SSM Card uses the FAT file system.
