Compaq Evo D510 e-pc - Audio

2–16 Technical Reference Guide
System Features
■
4x Blit Engine for 2D operations: 256 bit wide Blitter fills at a much greater rate than
memory bandwidth which speeds up operations like drop down menus
■
Deep Display Buffers: Buffer for screen refreshes which enables higher system performance
by reducing the CPU latency as well as decreasing the total transactions handled by the CPU
■
Non-blocking and multi-tier cache structures: Dedicated internal caches for textures, colors,
Z, and vertices which significantly reduces memory bandwidth and improves core
performance
■
Single-Pass Quad Texture Support: Supports up to blending operations for up to four textures
in a single pass which reduces memory bandwidth requirements and CPU loading
■
Texture Decompression: Provide up to 8x compression and consequent reduction in
bandwidth and footprint
Memory Usage with Dynamic Video Memory Technology
At boot time the system BIOS dedicates 8 MB of system memory for graphics display. When
more memory is needed the Intel 845G graphics driver submits a request to the operating system,
the operating system grants the request based upon available system memory. When the
application is closed, the OS will reallocate system memory back for generic use. The quantity of
additional memory which can be allocated for video by the operating system is limited, the limit
depends on the quantity of memory installed on the system and on the driver version (the latest
drivers can be downloaded from the web).
The quantity of system memory allocated by the BIOS and the maximum limit cannot be
modified by the user.
Connectors
A 15-pin VGA DB connector is located on the rear panel of the computer.
Audio
The audio solution on the Compaq Evo D510 e-pc is the Integrated Analog Devices AD1981A
AC’97 SoundMAX CODEC. The AD1981A interfaces directly with the South Bridge chip and
performs all digital operations, such as sample rate conversions and synthesis, as well as mixing
and processing the analog signals.
