13-2-2 A/V Processor (DIC1) Functional description
1) SPARC Processors
Two 32-bit SPARC processors, one dedicated to video processing and the other assigned general system tasks
and audio processing, perform three classes of functions: system processing, audio processing, and high-level
control flow and decision-making tasks for video processing. Optionally, they can also perform 2D graphics
and host functions.
The DMN8602 also support multiple video inputs, windowed video ad graphics with arbitrarily relocatable
and resizable windows, letterbox, and side-by-side display of SD sources.
2) Host Interface
The host communication functions include initializing the DMN-8602 device, downloading software to the
local SDRAM, sending commands, monitoring status, and downloading graphics data such as OSD bitmap.
