Abstract

This article describes a floating point processing element (FPPE) microcode matrix chart, hereinafter referred to as the matrix chart, a tool which aids the FPPE microprogram developer. FPPE microprogram source code mnemonics, entered by the microprogrammer, are translated by a computer program, the FPPE micro-assembler, to the actual object code which controls the processor. This source code, as is often the case with microprogram source code, is cryptic and does not represent the operations of the microprogram well.
