TK68020 Microprocessor
General Description
The TK68020 is a functional equivalent of the Motorola M68020 and they are pin-for-pin compatible. It is a full 32-bit implementation of the M68000 family of microprocessors from Motorola.
The TK68020 is a full 32-bit implementation of the 68000 family of microprocessors from Motorola. The TK68020 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes.
The TK68020 is object-code compatible with earlier members of the 68000 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 available. The internal operations of this microprocessor operate in parallel, allowing multiple instructions to be executed concurrently.
The asynchronous bus structure of the TK68020 uses a non-multiplexed 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.
