A Floating Point Processor for INTEL 8080A Microprocessor Systems,

Abstract

An A.M.D. 9511 Floating Point Processor has been interfaced to the Rutherford Laboratory Bubble Chamber Group's micro computers. These computers are based on the INTEL 8080A micro processor. The interface uses a memory mapped I/O technique to ensure rapid transfer of arguments between processors. The A.M.D. 9511 acts as a slave processor to the INTEL 8080A system. The 8080 processor is held in 'WAIT' status until completion of the A.M.D. operation. A software Macro Processor has been written to effectively extend the basic INTEL 8080A instruction set to include the full range of A.M.D. 9511 instructions. (Author)
