The Intel 8080 (pronounced "eighty-eighty") is Intel's second 8-bit microprocessor that played an important role in the evolution of early computing. Introduced in April 1974, the 8080 was an enhanced successor to the earlier Intel 8008 microprocessor, although without binary compatibility. [3]

英特尔8080 微处理器 是 英特尔 设计和制造的第二款 8位 微处理器。 它于1974年4月首次亮相，是早期 8008 设计的扩展和增强版本，尽管它们之间没有二进制兼容性。 最初规定的 时钟频率 或频率限制为2 MHz，常见指令使用4、5、7、10或11个周期。 因此，该处理器能够每秒执行数十万条指令。 后来推出了两个更快的变种，8080A-1和8080A-2，它们的时钟频率限制分别为3.125 MHz和2.63 MHz。 [2] 8080在大多数应用中需要两个支持芯片才能工作：i8224时钟生成器/驱 …

2014年12月18日 · Compared to the Intel 4004 and 8008 which preceded it, the 8080 was a far more powerful chip. Compared with the 4004's 2,300 transistors, the 8080 would end up with more than 4,500...

2024年12月26日 · In April 1974, Intel introduced the Intel 8080, a chip that would create the microprocessor market. Although it wasn’t the first microprocessor, it was the first truly general-purpose one, versatile enough to handle a wide range of applications from personal computing to industrial systems.

2024年12月30日 · Launched in April 1974, the Intel 8080 didn’t just change how computers worked; it transformed how the world interacted with technology. It was the first general-purpose microprocessor capable of running independently, paving the way for personal computers, embedded systems, and countless innovations.

2023年3月24日 · Intel 8080 microprocessor is a successor to the Intel 8008 CPU. The 8080 was designed by Federico Faggin and Masatoshi Shima. Stan Mazor contributed to chip design. The work on 8080 microprocessor was started at the end of 1972, and the CPU was released in …

Within a year of the introduction of Intel's first 8-bit CPU chip, the 8008, in April 1972, the author was working on the design specification for a faster and more capable CPU chip, the 8080. Here, the author describes the development of the 8080 …

The Intel 8085 is an 8-bit microprocessor introduced by Intel in 1977. It was backward binary compatible with the more-famous Intel 8080 (only adding a few minor instructions) but required less supporting hardware, thus allowing simpler and less expensive microcomputer systems to …

2007年4月1日 · One of the chip developers of the Intel 8080 8-bit CPU chip describes some of the key architectural decisions and the history of this very early microprocessor.

Intel released the 8080 microprocessor, destined to go down as one of the most important products in tech history, and saw several major milestones for its corporate operations, including two new international facilities (in the Philippines and Israel) and several key sales milestones.
