7.7 Memory Device

The memory device enables you to add memory devices to the system. You can configure the memory device for emulation of ROM or dynamic memory. You specify the total memory size and the beginning address to which the device should respond.

The memory device can also be configured as a LPC flash device. It currently models 2Mb (SST49LF020A), 4Mb (SST49LF040A), 8Mb (SST49LF080A) and 16Mb (SST49LF160C) flash memory devices. Note that we support two command sequences used generally by flash memory - SST and ATMEL. User should configure the flash memory to the appropriate command sequence to get desired results. The SST49LF160C

device uses the ATMEL command sequence while SST49LF020A/SST49LF040A/SST49LF080A use the SST command sequence.

Interfaces

The memory device has a general-purpose interface that you can connect to any other type of port. No selection is necessary when connecting this memory device to another device.

Initialization and Reset State

The default state of the device is a RAM memory device that is at a base address of 0x00000000 and a size of 4 Gigabytes. The memory has no default content. When an initialization file is specified, the memory device's contents contain the data from that binary file.

After a reset, the memory device reverts back to the initialization file contents.

Contents of a BSD

The contents of memory, as well as all configuration information, are stored in the BSD.

Configuration Options

The first field of the Memory Configuration tab, shown in Figure 7-14,is the base address of the device in a hexadecimal value.

The second field is the total size of the memory device, given in decimal value for the number of 32-Kbyte blocks you would like created (32-Kbyte blocks are used because non-initialized memory is dynamically allocated when addressed in 32-Kbyte chunks).

The third field is the name of the binary file you use to initialize the memory contents. The device 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. The Init File selection comes with a browse button for easier selection.

Selecting the Read-Onlyoption turns the memory device into a ROM. Writes to the device are ignored when the Read-Onlyoption is selected.

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.
