The Freescale™ MSC8144AMC-S provides an AMC debugging environment for engineers developing applications for the MSC8144 series of Freescale DSPs. The MSC8144AMC-S single-width AMC board is designed around four Freescale MSC8144 DSPs.

Each MSC8144 has 256 MB of associated 32-bit-wide DDR2 memory. High throughput RapidIO links connect the four MSC8144s to each other and to the data backplane. The RapidIO interfaces can run in x1 or x4 mode and are interconnected via the Tundra Tsi578. For the control plane, each MSC8144 RGMII gigabyte Ethernet port is linked to the backplane ports through an Ethernet switch. An optional shared TDM interface is routed from each MSC8144 to the backplane extended ports.

For bootstrap purposes, a common I2C bus and EEPROM are connected between the MSC8144 devices. The EEPROM is programmed through a master MSC8144 or an in-circuit programmer attached to a header. AMC board management is handled via a Module Management Controller based around a Freescale MCF5213. The provides the board with power sequencing, hot swap functionality, temperature sensing, and FRU record storage. A number of debug and programming headers are offloaded to an expansion card through the front panel.
