8087

The intel 8087 Math CoProcessor is an extension to the 8086/8088 microprocessor architecture.When combined with the 8086/8088 microprocessor, the 8087 dramatically increases the processing speed of computer applications which utilize mathmatical operations such as CAM, numeric controlelrs, CAD or graphics.

Features of the 8087 are:(1)adds arithmetic, trigonometric, exponential, and logarithmic instructions to the standard 8086/8088 and 80186/80188 instruction set for all data types; (2)CPU/8087 supports 7 data types:16-,32-,64-bit integers,32-,64-,80-bit floating point, and 18-digit BCD operands; (3)compatible with IEEE floating point standard 754; (4)7 built-in exception handling functions.

The absolute maximum ratings of the 8087 can be summarized as:(1): ambient temperature under bias is 0 to 70; (2): storage temperature is -65 to +150; (3): voltage on any pin with respect to ground is -1.0 V to +7 V ; (4): power dissipaiton is 3.0 watt.
