9.1. IPMC
The SmartFusion cSOC A2F500 is made by integrating FPGA technology with
programmable high performance analog and hardened ARM Cortex-M3 microcontroller
blocks on a flash semiconductor process. The three key building blocks include:
Microcontroller Subsystem (MSS), Programmable Analog, and ProASIC3 FPGA Fabric.
The MSS is composed of a 100 MHz Cortex-M3 processor and integrated peripherals,
which are SPI, I2C, and UART serial ports, embedded FlashROM (EFROM), 10/100
Ethernet MAC, timers, PLLs, oscillators, RTC, and peripheral DMA controller. The
Programmable Analog Subsystem has Analog Front-End (AFE) and Analog Compute
Engine (ACE). The ProASIC3 FPGA Fabric gives benefits from the advantages only
flash-based devices offer such as reduced cost of ownership, low power and security.
The features of the IPMC A2F500 are summarized in Table 9-1.

The operating system on embedded ARM processor is FreeRTOS, which is a portable,
open source, royalty free, mini real-time kernel (www.freertos.org). Most essential
driver packages are available from the SmartFusion SDK.
