1 / 88 page  Freescale Semiconductor Technical Data MSC8122 Rev. 13, 10/2006 © Freescale Semiconductor, Inc., 2004, 2006. All rights reserved. MSC8122 Quad Core 16-Bit Digital Signal Processor The MSC8122 is a highly integrated system-on-a-chip that combines four SC140 extended cores with an RS-232 serial interface, four time-division multiplexed (TDM) serial interfaces, thirty-two general-purpose timers, a flexible system interface unit (SIU), an Ethernet interface, and a multi-channel DMA engine. The four extended cores can deliver a total 4800/6400/8000 DSP MMACS performance at 300/400/500 MHz. Each core has four arithmetic logic units (ALUs), internal memory, a write buffer, and two interrupt controllers. The MSC8122 targets high-bandwidth highly computational DSP applications and is optimized for wireless transcoding and packet telephony as well as high-bandwidth base station applications. The MSC8122 delivers enhanced performance while maintaining low power dissipation and greatly reducing system cost. Figure 1.

The MSC8122 is offered in three core speed levels: 300, 400, and 500 MHz. What’s New? Rev. 13 includes the following: •Chapter 2 updates Table 2-13 to add timings 17 and 18 for IRQs. |
