MC68030, Second Generation 32-Bit HCMOS Microprocessor
The 030 contains two independent 32-bit address buses and two 32-bit data buses which allows the the CPU, caches,
MMU, and the bus controller to operate in parallel. This makes it possible for the 030 to simultaneously access an
instruction from the instruction cache, data from the data cache and instruction/data from external memory. Performance
is further enhanced by on-chip 256 byte instruction and data caches, on-chip MMU, and enhanced bus controller.

MC68040, Third Generation 32-Bit HCMOS Microprocessor
The 040 is a virtual memory microprocessor employing multiple, concurrent execution units and a highly integrated
architecture. On a single chip, the 040 integrates a MC68030 compatible integer unit, an IEEE 754 compatible floating point
unit (FPU) and fully independent instruction and data demand-paged memory units (MMUs), including independent 4 K-byte
instruction and data caches. A high degree of parallelism is achieved through use of multiple independent execution pipelines,
multiple internal buses, and a full Harvard architecture, including separate physical caches for instruction and data accesses.
The 040 also directly supports cache coherency in multimaster applications with dedicated on-chip bus snooping logic.
