Motorola 68010

<processor> A microprocessor from Motorola. It was the successor to the Motorola 68000 and was followed by the Motorola 68020. Some instructions which were previously user mode were made system mode, which necessitated patches to a few programs.

The 68010 also had a primitive cache. The DBxx instructions (decrement and branch) were cached, along with a few previous instructions. Small loops could thus execute from the cache directly.

At one time there was a 68010 variant that was pin-for-pin compatible with the 68000. Early Amiga hackers replaced their 68000s with 68010s in order to get a small performance increase.
