CRT9006-135 - Single Row Buffer

General Description

The SMC Single Row Buffer (SRB) provides a low cost solution to memory contention between the system processor and CRT controller in video display systems.

The SRB is a RAM-based buffer which is loaded with character data from system memory during the first scan line of each data row.

Key Features

  • D Low Cost Solution to CRT Memory Contention Problem D Provides Enhanced Processor Throughput for CRT Display Systems D Provides 8 Bit Wide Variable Length Serial Memory D Permits Active Video on All Scan Lines of Data Row D Dynamically Variable Number of Characters per Data Row- 64,80, 132, up to a Maximum of 135 D Cascadable for Data Rows Greater than 135 Characters D Stackable for Invisible Attributes or Character Widths of Greater than 8 Bits D Three-State Outputs D 4MHz Typical Read/Writ.
