Revision as of 09:01, 23 November 2018
The AMD Am2900 is a family of 4-bit bit-slice chips designed by Advanced Micro Devices and introduced to the market in August 1975. Each component represents an individual unit in a microprocessor. Designed to be flexible and expandable, those chips were capable of emulating a large number of existing systems. Made in bipolar technology allowed for higher speeds (1-20Mhz, later up to 32). Its flexibility, higher speed, unusually large amount of 2nd sources, and good marketing allowed AMD to dominate the bit-slice market. To date, the Am2900 family is used as the de facto baseline for bit-slice design.
Design
The family includes two 4-bit ALUs - 2901 and a 2903. The AM2901/A was the original chip designed, supporting 8 different basic operations. The AM2903/A was an enhanced version designed a bit later which included 7 additional operations. The slices can be stacked to produce 8, 12, or 16 data paths and memory addresses for use in larger programs.
This section requires expansion; you can help adding the missing info. |
2nd sources
The Am2900 had a large number of 2nd sources:
75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 |
