Description
The PC7447A host processor is a high-performance, low-power, 32-bit implementations of the PowerPC
Reduced
Instruction Set Computer (RISC) architecture combined with a full 128-bit implementation of Freescale’s AltiVec
technology.
This microprocessor is ideal for leading-edge embedded computing and signal processing applications. The PC7447A fea-
tures 512 KB of on-chip L2 cache. The PC7447A microprocessor has no backside L3 cache, allowing for a smaller
package designed as a pin-for-pin replacement for the PC7447 microprocessor. This device benefits from a silicon-on-
insulator (SOI) CMOS process technology, engineered to help deliver tremendous power savings without sacrificing speed.
A low-power version of the PC7447A microprocessor is also available.
Figure 1-1 on page 2 shows a block diagram of the PC7447A. The core is a high-performance superscalar design support-
ing a double-precision floating-point unit and a SIMD multimedia unit. The memory storage subsystem supports the MPX
bus protocol and a subset of the 60x bus protocol to the main memory and other system resources.
Note that the PC7447A is a footprint-compatible, drop-in replacement in a PC7447 application if the core power supply is
1.3V.
