Overview

The MC68020 is the first full 32-bit implementation of the M68000 family of microprocessors from Motorola. Using VLSI technology, the MC68020 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes.The MC68020 is object-code compatible with earlier members of the M68000 family and has the added features of new addressing modes in support of high-level languages, an on-chip instruction cache, and a flexible coprocessor interface with full IEEE floating-point support (the MC68881 and MC68882). The internal operations of this microprocessor operate in parallel, allowing multiple instructions to be executed concurrently.The asynchronous bus structure of the MC68020 uses a nonmultiplexed bus with 32 bits of address and 32 bits of data. The processor supports a dynamic bus sizing mechanism that allows the processor to transfer operands to or from external devices while automatically determining device port size on a cycle-by-cycle basis. The dynamic bus interface allows access to devices of differing data bus widths, in addition to eliminating all data alignment restrictions.
