description This note describes the performance and instruction timing of the System/360 Emulators for EMMY. General emulator structure and flow are included in a previous report. A detailed description of the final complete Class B emulator will be the subject of a later report. The Stanford EMMY will emulate typical 360 instruction streams at about 97KIPS. A production (Model 2 Control Store) EMMY will achieve 143KIPS on the same instruction stream. A 360 model 50 processes this stream at about 141KIPS. Minor modifications to the Stanford machine should enable it to achieve 120KIPS. (Author)
