MC68360 PRODUCT INFORMATION
5
fetch two word-length instructions in one bus cycle, filling the internal instruction queue more quickly. The
CPU32+ core can also read and write 32-bits of data in one bus cycle.
Although the CPU32+ instruction timings are improved, its instruction set is identical to that of the CPU32. It
will also execute the entire M68000 instruction set. It contains the same background debug mode (BDM)
features as the CPU32. No new compilers, assemblers, or other software support tools need be
implemented for the CPU32+; standard CPU32 tools can be used.
The CPU32+ delivers approximately 4.5 MIPS at 25 MHz, based on the standard (accepted) assumption that
a 10-MHz M68000 delivers 1 VAX MIPS. If an application requires more performance, the CPU32+ can be
disabled, allowing the rest of the QUICC to operate as an intelligent peripheral to a faster processor. The
QUICC provides a special mode called MC68040 companion mode to allow it to conveniently interface to
members of the M68040 family. This two-chip solution provides a 22-MIPS performance at 25 MHz.
The CPU32+ also offers automatic byte alignment features that are not offered on the CPU32. These
features allow 16 or 32-bit data to be read or written at an odd address. The CPU32+ automatically performs
the number of bus cycles required.
System Integration Module (SIM60)
The SIM60 integrates general-purpose features that would be useful in almost any 32-bit processor system.
The term “SIM60” is derived from the QUICC part number, MC68360. The SIM60 is an enhanced version of
the SIM40 that exists on the MC68340 and MC68330 devices.
First, new features, such as a DRAM controller and breakpoint logic, have been added. Second, the SIM40
was modified to support a 32-bit IMB as well as a 32-bit external system bus. Third, new configurations, such
as slave mode and internal accesses by an external master, are supported.
Although the QUICC is always a 32-bit device internally, it may be configured to operate with a 16-bit data
bus. Regardless of the choice of the system bus size, dynamic bus sizing is supported. Bus sizing allows 8-,
16-, and 32-bit peripherals and memory to exist in the 32-bit system bus mode and 8- and 16-bit peripherals
and memory to exist in the 16-bit system bus mode.
Communications Processor Module (CPM)
The CPM contains features that allow the QUICC to excel in communications and control applications. These
features may be divided into three sub-groups:
Communications Processor (CP)
Two IDMA Controllers
Four General-Purpose Timers
The CP provides the communication features of the QUICC. Included are a RISC processor, four SCCs, two
SMCs, one SPI, 2.5 Kbytes of dual-port RAM, an interrupt controller, a time slot assigner, three parallel ports,
a parallel interface port, four independent baud rate generators, and fourteen serial DMA channels to
support the SCCs, SMCs, and SPI.
The IDMAs provide two channels of general-purpose DMA capability. They offer high- speed transfers, 32-
bit data movement, buffer chaining, and independent request and acknowledge logic. The RISC controller
may access the IDMA registers directly in the buffer chaining modes. The QUICC IDMAs are similar to, yet
enhancements of, the two DMA channels found on the MC68340 and the one IDMA channel found on the
MC68302.
