Automation Command

 

Description

Save <filename>

 

Creates file „filename‟ and saves the contents of the

 

currently loaded ROM „to filename‟.

 

 

 

Load <filename>

 

Loads the specified MemDevice „filename‟ to defined

 

address „BaseAddress‟.

 

 

 

BaseAddress <value>

 

„Value‟ is the base address of the device in hex.

GetBaseAddress

 

Returns the base address of the device in hex.

 

 

 

„Value‟ is the total size of the memory device, given in

 

 

 

decimal value for the number of 32-Kbyte blocks (32-

SizeInBlocks <value>

 

Kbyte blocks are used because not initialized memory is

 

 

 

dynamically allocated when addressed in 32-Kbyte

 

 

 

chunks).

GetSizeInBlocks

 

Returns the number of 32-Kbyte blocks allocated by this

 

device.

 

 

 

 

 

 

„filename‟ is the name of the binary file that is used to

 

 

 

initialize the memory contents. Note that the device

InitFile <filename>

 

initializes memory for the content length of the file. If

 

 

 

you specify a 512-Kbyte ROM and use a 256-Kbyte

 

 

 

image file, the first 256 Kbytes are initialized.

GetInitFile

 

Returns the path and name of the init file (see above

 

InitFile).

 

 

 

 

 

 

Turns (1) the memory device into a ROM. Writes to the

ReadOnly <01>

 

device are ignored when the read-only option is

 

 

 

selected.

GetReadOnly

 

Returns true if memory is read-only otherwise it returns

 

false.

 

 

 

SystemBios <01>

 

Tells (1) the memory device that it is the system BIOS.

GetSystemBios

 

Returns true if memory is used as a System BIOS

 

otherwise it returns false.

 

 

 

 

 

 

Enables (1) or disables (0) memory-address masking. If

 

 

 

enabled (1) it indicates that the address received by the

 

 

 

memory device is masked by a bit mask with the same

MemAddrMask <01>

 

number of bits as the size of the memory device (e.g., a

 

256-Kbyte ROM uses an 18-bit mask, or it is masked by

 

 

 

 

 

 

0x003FFFF). This enables the ROM to be remapped

 

 

 

dynamically into different memory address ranges in

 

 

 

conjunction with the aforementioned chip select.

GetAddrMask

 

Returns true if memory-address masking is enabled

 

otherwise it returns false.

 

 

 

 

 

 

Enables (1) or disables (0) the initialized unwritten

InitValEnable <01>

 

memory option. If enabled the memory is initialized

 

using a specified byte (see below InitVal) otherwise the

 

 

 

 

 

 

memory is not initialized.

InitVal <hex value>

 

Sets byte initializer for memory that needs to be

 

initialized.

4.4.5 specifications

AMD 4.4.5 is a robust version of the AMD software ecosystem that focuses on enhanced performance, stability, and efficiency for users relying on AMD processors and graphics cards. This iteration brings various features and technologies designed to optimize gaming, professional applications, and general computing tasks.

One of the standout enhancements in AMD 4.4.5 is the integration of Smart Access Memory technology, which allows the CPU to access the full graphics memory directly. This feature enhances data flow between the CPU and GPU, leading to improved frame rates and overall performance, especially in memory-intensive games. Users can experience a marked increase in gaming performance without the need for additional hardware upgrades.

Another significant feature introduced is the updated Radeon Software Adrenalin Edition. This software update encompasses optimizations for various games, ensuring that gamers can enjoy a seamless experience with the latest titles. The Adrenalin interface also provides features such as Radeon Chill, which helps reduce power consumption during less demanding scenes, and Radeon Anti-Lag, designed to minimize input lag and enhance responsiveness in competitive gaming.

Additionally, AMD 4.4.5 brings the latest drivers that include important performance enhancements and bug fixes that allow for greater system stability. Regular updates ensure that users have the best experience with their AMD hardware, and it significantly bolsters compatibility with the latest gaming titles and software applications.

AMD's Enhanced Sync technology offers users the ability to eliminate screen tearing and stuttering while delivering smooth gameplay. It dynamically synchronizes the refresh rate of the display with the frame rates produced by the GPU, improving the visual experience significantly.

With the introduction of FidelityFX Super Resolution, AMD continues to bolster its suite of technologies that enhance graphics quality and performance. This feature allows lower-resolution images to be upscaled effectively, making it easier for users to enjoy high-end visuals without taxing their hardware excessively.

In summary, AMD 4.4.5 represents a comprehensive update for users by integrating cutting-edge technologies that cater to a wide range of applications from gaming to content creation. With enhancements across the board, AMD reaffirms its commitment to providing high-performance solutions that keep pace with the ever-evolving technology landscape. Whether for gaming aficionados or professional creators, the capabilities offered in this version make it a significant milestone in the AMD software ecosystem.
