CDP1855 Overview
The CDP1855 and CDP1855C are CMOS 8-bit multiply/divide units which can be used to greatly increase the capabilities of 8-bit microprocessors. They perform multiply and divide operations on unsigned, binary operators. In general, microprocessors do not contain multiply or divide instructions and even efficiently coded multiply or divide subroutines require considerable memory and execution time.
CDP1855 Key Features
- Cascadable Up to 4 Units for 32-Bit by 32-Bit Multiply or 64 ÷ 32-Bit Divide
- Direct Interface to CDP1800-Series Microprocessors
