This paper describes the design of a 43-bit floating-point RISC microprocessor with double precision. Several innovations, which include a new type of embedded bus arbiter control bus, a new type of trap handler manage interrupt, a new type of data link control memory and the high order Booth's algorithm, are used to design this microprocessor. 128K SRAM is also embedded in microprocessor. We make use of 0.25?滋m CMOS technology synthesis and make layout. Post-simulation and emulation with CPLD indicate that the microprocessor is normal to run.
