The poorer thermal characteristics of the QFP package limited the full 68030 QFP variant to 33 MHz; the PGA 68030s included 40 MHz and 50 MHz versions. The 68030 has an on-chip except in the 680EC30 version.

Coprocessors allow a line of computers to be customized, so that customers who do not need the extra performance do not need to pay for it. Bibliography note Includes bibliographical references pages 563-564 and index Carrier category online resource Carrier category code• The previous 68000 and 68010 processors could only access word 16 bit and longword 32 bit data if it were word-aligned located at an address that is evenly divisible by 2.
Variants The 68EC030 is a low cost version of the 68030, the difference between the two being that the 68EC030 omits 68030 microprocessors and their coprocessors on-chip memory management unit MMU and is thus essentially an upgraded 68020. Chapter 15 is devoted to the MC68030 processor.
This is followed by the body of the chapter, which includes many programming and hardware application examples that illustrate the main topics. MICROCOMPUTER ARCHITECTURE; Questions and Problems; 3. The coprocessor interface is asynchronous, so it is possible to run the coprocessors at a different clock rate than the CPU.
The 68020 had a minimal 256 byte direct-mapped instruction cache, arranged as 64 four-byte entries.
Improvements over 68010 The 68020 added many improvements to the 68010 including a 32-bit ALU , external data bus and address bus, and new instructions and addressing modes.
