  • The MC88100 is a microprocessor developed by Motorola that implemented 88000 RISC instruction set architecture. Announced in 1988, the MC88100 was the first 88000 implementation. It was succeeded by the MC88110 in the early 1990s. The microprocessor has separate pipelined integer, floating-point add, floating-point multiply, and load/store execution units and dispatches a single instruction (at most) per clock cycle. The separate MC88200 integrated circuit optionally add level 1 cache and a paged memory management unit. An MC88100 system typically used two of these devices for instructions and data; additional MC88200s could be added to increase the size of the caches. This partitioned scheme was chosen to provide system flexibility, the amount of cache could be varied depending on the price point. In practice, these additional chips required more space on the circuit board and the buses between the MC88200s and MC88100 added complexity and cost. The MC88100 contained 165,000 transistors and the MC88200 750,000 transistors. Both were fabricated by Motorola in its 1.5 μm complementary metal–oxide–semiconductor process. The MC88100 was ultimately commercially unsuccessful. This was due to a number of reasons, including requirement of MC88200s, but was mostly due to Motorola being a vendor of the highly successful 68000 family. As the 68000 division viewed the 88000 as a competitor, they forced the MC88100 to be priced unacceptably high for a volume part. The part did find use in the high-end embedded market, in Motorola's own computers, and in large computers from companies such as Data General and the Unisys S-8400 Unix Servers. (en)
  • MC88100 – mikroprocesor typu RISC produkowany od roku 1989 do połowy lat dziewięćdziesiątych przez firmę Motorola. Należy do rodziny M88000, znanej także jako 88k. Układ zawierał 32 32-bitowe rejestry, wbudowany arytmometr stało- i zmiennoprzecinkowy oraz rozszerzalna listę instrukcji. Przy taktowaniu rzędu 20 MHz układ osiągał wydajność obliczeniową na poziomie 15 MIPS. W jednym komputerze możliwe było zastosowanie czterech układów MC88100. (pl)
