Review AMD Two Ftgold Topft Integrated Circuits Vintage Untested

The AMD Am9517A FTGLOD top logic integrated circuit, manufactured by Advanced Micro Devices (AMD) in 1978-1979, was a significant addition to the semiconductor industry and played a crucial role in the evolution of microprocessors. This 16-bit application-specific integrated circuit (ASIC) was designed for use in the control of automatic precise motion control systems, such as industrial machinery, precision machining, and computer-controlled motors.

The Am9517A FTGLOD is designed around a Harvard architecture CPU with a clock speed of 2.2 MHz, supporting a 16-bit data path and a 17-bit instruction set. It includes a level 1 data cache of 256 bytes, which can be accessed in a single clock cycle, improving overall processing efficiency for the targeted applications.

1. A 16-bit ALU (Arithmetic and Logic Unit) capable of performing arithmetic and bitwise operations.

2. A 16x16 multiplier.

3. Three 16-bit general-purpose registers (GPRs).

4. Three 17-bit instruction registers.

5. Five 17-bit addressing modes, enabling access to both memory and I/O ports.

6. Fifteen 8-bit I/O ports (two bi-directional and thirteen output-only).

7. A 16-bit temporal register for handling delayed branching and other timing-related functions.

The Am9517A FTGLOD also supports various addressing modes suitable for industrial control applications, such as immediate, register-indirect, stack-pointer, and indexed addressing. In addition, it provides useful control instructions, like jump, call, return, and halt.

The manufacturing process employed a bipolar CMOS Technology, with a gross die size of approximately 4.05 square inches. Considering the time period, this was a considerable achievement in semiconductor manufacturing. The chip's power consumption was relatively low, making it suitable for battery-powered systems and other power-sensitive applications.

In summary, the AMD Am9517A FTGLOD was an essential integrated circuit for industrial control systems during the late 1970s, providing superior performance, power efficiency, and versatility. It laid the groundwork for future microprocessors, demonstrating AMD's commitment to innovation and excellence in the semiconductor industry.

The AMD AM9517A FTGold TopFET integrated circuits were advanced microprocessors introduced by Advanced Micro Devices (AMD) in the late 1970s. These chips were notable for their high level of integration and improved performance compared to earlier microprocessors. Here are some pros and cons if you're considering buying AMD AM9517A FTGold TopFET integrated circuits.

1. High level of integration: The AMD AM9517A FTGold TopFET chips integrated multiple functions onto a single chip, reducing the number of components required in a system and improving system density.

2. Improved performance: Compared to earlier microprocessors, the AMD AM9517A FTGold TopFET offered improved performance, allowing systems to run more complex software and perform calculations faster.

3. Backward compatibility: These chips were designed to be backwardly compatible with earlier AMD microprocessors, making them a popular choice for upgrades and system expansions.

4. Cost-effective: Due to their high level of integration and backward compatibility, the AMD AM9517A FTGold TopFET chips were cost-effective solutions for building systems during the late 1970s and early 1980s.

1. Obsolete technology: The AMD AM9517A FTGold TopFET chips are now obsolete and no longer produced. This may make them difficult to find and expensive to purchase.

2. Limited availability: Due to their age and obsolescence, these chips may be difficult to find in the market.

3. Compatibility issues: Older hardware and systems may not be compatible with modern technologies, making it difficult to integrate these chips into modern systems.

4. Requirements for vintage hardware: To use the AMD AM9517A FTGold TopFET chips, you will need vintage hardware that is compatible with these chips. This may limit their practical uses in modern times.

The AMD AM9517A FTGold TopFET integrated circuits were groundbreaking technologies in their time, offering high levels of integration and improved performance compared to earlier microprocessors. However, due to their age and obsolescence, they may be difficult to find and expensive to purchase. Moreover, their limited compatibility with modern technologies and hardware makes them more of a curiosity than a practical solution for modern computing needs.

While the AMD AM9517A FTGold TopFET integrated circuits may hold historical significance and interest for vintage computing enthusiasts, they are not a practical solution for modern computing needs due to their obsolescence and limited availability. Instead, it is recommended to focus on modern technologies and hardware that offer comparable or better performance and are more practical for today's computing requirements.
