The Motorola 68040 is a third-generation, high-performance, full 32-b microprocessor. The caches, memory-management units (MMUs), and autonomous controllers for the caches and external bus that comprise the memory subsystem are described. The 68040's memory subsystem supports the performance of the integer and floating-point units by using autonomous(More)
The Motorola System on Chip Design Technologies (SoCDT) team aims at providing a system design environment for its customers. The Toulouse branch concentrates on design efforts incorporating DSP functionality. This is referred to as the Catalyst methodology. We found that in current systems very often the software development cycle is longer than that of(More)
The integer, floating-point, and on-chip memory subsystems of the Motorola 68040 microprocessor operate in parallel to achieve four times the performance of a 68020 microprocessor and ten times the performance of a 68882 floating-point coprocessor. The integer and floating-point units are described in terms of their performance, internal architecture, and(More)
