摘要
The ESA/390 high-end CISC architecture has been implemented using a 1.0 um CMOS standard cell technology. The resulting 4 chip, 2.5 Mio. transistor microprocessor is used in IBM's 9221 line of midrange systems. This paper gives an overview of the technology used and a description of the implementation. The dataflow and pipelining scheme are described. Instructions of low complexity are executed RISC-like in a single cycle under full hardware-control, while comple instructions are interpreted by microcode.
