AMD Am9080
The Am9080 was a CPU manufactured by AMD. Originally produced without license as a clone of the Intel 8080, the processor was reverse-engineered by Ashawna Hailey, Kim Hailey and Jay Kumar by photographing an early Intel chip and developing a schematic and logic diagrams from the images. In initial production, the chips cost about 50 cents to make, yielding 100 chips per wafer, and were sold into the military market for $700 each. This CPU operated at a speed of 2 MHz The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose formal expression in terms of SI base u .... Later, an agreement was made with Intel to become a licensed second source for the 8080, enabling both manufacturers' chips to break into markets that would not accept a single-sourced part.

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary Processor (computing), processor in a given computer. Its electronic circuitry executes Instruction (computing), instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, CPU design, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic operation, arithmetic and Bitwise operation, logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the #Fetch, fetching (from memory), #Decode, decoding and ...

Intel 8080
The Intel 8080 is Intel's second 8-bit computing, 8-bit microprocessor. Introduced in April 1974, the 8080 was an enhanced successor to the earlier Intel 8008 microprocessor, although without binary compatibility.'' Electronic News'' was a weekly trade newspaper. The same advertisement appeared in the :File:Intel 8080 Advertisement May 1974.jpg, May 2, 1974, issue of ''Electronics'' magazine. Originally intended for use in Embedded system, embedded systems such as calculators, cash registers, computer terminals, and industrial robots, its robust performance soon led to adoption in a broader range of systems, ultimately helping to launch the microcomputer industry. Several key design choices contributed to the 8080’s success. Its 40‑pin package simplified interfacing compared to the 8008’s 18‑pin design, enabling a more efficient data bus. The transition to NMOS logic, NMOS technology provided faster transistor speeds than the 8008's PMOS logic, PMOS while also simplifyin ...

Ashawna Hailey
Ashawna Hailey (October 8, 1949 – October 14, 2011) was an American computer scientist and philanthropist. She was among the creators of the HSPICE program (a commercialized version of SPICE), which many electronic design companies worldwide use to simulate the electronic circuits. Her company, Meta-Software, which was behind the commercialization of SPICE, produced compound annual growth rate in excess of 25–30 percent every year for 18 years, and had eventually become part of Synopsys, which calls HSPICE "the 'gold standard' for accurate circuit simulation". Early life and education Hailey attended Texas Tech University along with her twin brother, Kim Hailey, starting her first company while still in college. Career In 1973, Hailey was part of the team who created Advanced Micro Devices' first microprocessor, the Am9080, by reverse-engineering Intel 8080, and in 1974, AMD's first nonvolatile memory, the 2702 2048-bit EPROM. Earlier, she, with others, built the launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jay Kumar
Jays are a paraphyletic grouping of passerine birds within the family Corvidae. Although the term "jay" carries no taxonomic weight, most or all of the birds referred to as jays share a few similarities: they are small to medium-sized, usually have colorful feathers and are quite noisy. These superificial characteristics set them apart from most other corvids such as crows, ravens, jackdaws, rooks and magpies, which are larger and have darker plumage. Many so-called "jays" are genetically closer to these other corvids than other jays, however. Systematics and species Jays are not a monophyletic group. Anatomical and molecular evidence indicates they can be divided into a New World and an Old World lineage (the latter including the ground jays and the piapiac), while the grey jays of the genus ''Perisoreus'' form a group of their own.http://www.nrm.se/download/18.4e32c81078a8d9249800021299/Corvidae%5B1%5D.pdf PDF fulltext The black magpies, formerly believed to be related to ...

Second Source
In the electronics industry, a second source is a company that is licensed to manufacture and sell components originally designed by another company (the first source). It is common for engineers and purchasers to seek components that are available from multiple sources, to avoid the risk that a problem with one supplier would prevent a product from being manufactured. For simple components such as resistors and transistors, this is not usually an issue, but for complex integrated circuits, vendors often react by licensing one or more other companies to manufacture and sell the same parts as second sources. While the details of such licenses are usually confidential, they often involve cross-licensing, so that each company also obtains the right to manufacture and sell parts designed by the other. In the early TTL device period wafers were smaller so production was limited. More production lead to lower prices and new designs rapidly emerged. Examples MOS Technology licensed ...
