  • Patent number: 5983328
    Abstract: A microcomputer is disclosed which is specifically designed for computation-intensive applications. The microcomputer contains on-chip RAM and ROM, and has peripheral ports for access of external memory and input/output functions. The central processing unit further contains two auxiliary arithmetic logic units, in parallel with one another, and which are each connected to a set address lines in a memory bus; the two auxiliary arithmetic logic units thus generate two separate memory addresses in parallel. The memory bus also contains one set of data lines, connected to the RAM and ROM, and to the central processing unit. The on-chip RAM and ROM are responsive to the two sets of address lines in time-multiplexed fashion to provide memory access via data lines twice per system clock cycle.
    Type: Grant

  • Patent number: 5179689
    Abstract: A microcomputer is disclosed which is specifically designed for computation-intensive applications. The microcomputer contains on-chip RAM and ROM, and has peripheral ports for access of external memory and input/output functions. The microcomputer has a central processing unit with a floating-point multiplier in parallel with an arithmetic logic unit, and uses a plurality of registers as multiple accumulators. The central processing unit further contains two auxiliary arithmetic logic units, in parallel with one another, and which are each connected to a set of address lines in a memory bus; the two auxiliary arithmetic logic units thus generate two separate memory addresses in parallel. The memory bus also contains one set of data lines, connected to the RAM and ROM, and to the central processing unit.

The microprocessor has a central processing unit with a floating-point multiplier in parallel with an arithmetic logic unit, and uses a plurality of registers as multiple accumulators. The central processing unit further contains two auxillary arithmetic logic units, in parallel with one another, and which are each connected to a set of address lines in a memory bus; the two auxillary arithmetic logic unit thus generate two separate memory addresses in parallel. The memory bus also contains one set of data lines, connected to the RAM and ROM, and to the central processing unit. The on-chip RAM and ROM are responsive to the two sets of address lines in time-multiplexed fashion to provide memory access via data lines twice per system clock cycle.
