Intel C3002 - 2b Bit Slice Microprocessor (NOS, 3002, Computer Chip
Item History & Price
| Reference Number: Avaluer:51465454 | Brand: Intel |
| Type: Microprocessor |
About this Listing:This listing is for a very rare new-old-stock Intel 3002 microprocessor. The chip offered here is a never used new-old-stock Intel C3002. There is a scratch on the lid of the C3002, however, the lettering is over the scratch, so the scratch happened as part of the manufacturing process. The leads are gold and the body is white ceramic. This chip would be a great addition to your microprocessor collection.About the Intel 3002:
When is a CPU not a CP...U? Answer: when it's a bit-slice microprocessor. The Intel 3002 was Intel's entry into the bit-slice marketplace. The bit-slice architecture is one of the most interesting in microprocessor design. A bit-slice microprocessor's logic is divided into two chips: the Control Unit (CU) and the Arithmetic and Logic Unit (ALU). The 74181 was the 1st ALU, but had no corresponding CU chip. For the Intel 3000 series, the 3002 was the ALU and the 3001 was the CU. Introduced in 1974, it was an unusual device in that it was a 2-bit ALU while most other bit-slice devices were 4-bit. In addition, the 3002 was a bipolar device and very fast.
The Bit-slice microprocessor design has three very significant advantages. The first is that the ALU's can be used in a horizontal configurations to create computers that can handle very large chunks of data at a time. The 3002 is a peer of the Intel 8080, but the 8080 could only handle 8-bits of data at time. The 3002 was a 2-bit ALU, but 8 3002's could be linked together to create a computer that could handle 16-bits at a time, 16 could be put together to create a 32-bit computer and so on. Whereas the 8080 would have to use multiple cycles to process 16 or 32 bits, an appropriate 3002 configuration could handle it in a single cycle giving such a computer significantly more power than the 8080. The second, advantage of the Bit-slice design is the fact that two chip design allowed the chips to use bipolar chip technology. Bipolar is very fast, but consumes lots of power and dissipates lots of heat. Because of the heat dissipation problem, bipolar chips could not be as dense (in number of transistors per area) as the PMOS or NMOS chips. It was not possible to build single-chip CPU's using bipolar technology. So, in addition to the wider data paths the Bit-slice devices could achieve, they were inherently faster due to the bipolar technology that was employed to build the chips. The third advantage the Bit-slices had was the ability to allow users to create their own instruction sets for their applications. Instruction sets could be created to emulate, or enhance, existing processors such as the 6502 or 8080, or to create a unique instruction set specially adapted to maximize performance of a specific application. The combination of the speed and flexibility of Bit-slice devices made them very popular.Want to see more AntiqueTech items?
