M32000D4AFP
SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M32000D4AFP is a new generation microcomputer with a 32-bit
CPU and built-in high capacity DRAM. Using this device it is possible
to implement the complex applications of the multimedia age with
high performance and low power consumption.
The M32000D4AFP contains 2M bytes of DRAM and 4K bytes of
cache memory. The CPU is implemented with a RISC architecture
and has a high performance figure of 52.4 MIPS (at an internal clock
rate of 66.6 MHz ). Memory for main storage is provided internally to
the device eliminating external memory and associated control cir-
cuits thus reducing overall system noise and power consumption.
The CPU, internal DRAM and cache memory are connected by a
128-bit, 15 ns/cycle internal bus which virtually eliminates transfer
bottlenecks in between the CPU and the memory. The M32000D4AFP
internally multiplies the frequency of the input clock signals by four.
For an internal operating frequency of 66.6 MHz the input clock fre-
quency is 16.65MHz.
A 16-bit data and 24-bit address bus are the M32000D4AFP's exter-
nal bus and the interface to external peripheral controllers. When the
hold state is set, the internal DRAM can be accessed from an exter-
nal device.
A 3-chip basic system configuration using the M32000D4AFP is the
device itself plus an ASIC as a peripheral controller and a program
ROM. Execution starts from the reset vector entry on the external
ROM after power on, a program requiring high speed execution is
then transferred to internal DRAM and this is then executed. The
M32000D4AFP also has a slave mode additional to its master mode.
When set to slave mode the M32000D4AFP can be used as a
coprocessor. In this mode it does not access its external bus
immediatly after reset, but waits for the master to start its operation.
