STLS2F01 High performance 64-bit superscalar MIPS microprocessor

The STLS2F01 is a MIPS based 64-bit superscalar microprocessor, able to issue four instructions per clock cycle among six functional units: two integer, two single/double-precision floating-point, one 64bit SIMD and one load/store unit. The micro architecture is organized with ninestage of pipeline and support of dynamic branch prediction. Table 1. Device su.
