The level-1 (L1) program and data memories on the TCI6482 device are 32KB each. This memory can be configured as mapped RAM, cache, or some combination of the two. When configured as cache, L1 program (L1P) is a direct mapped cache where as L1 data (L1D) is a two-way set associative cache. The level-2 (L2) memory is shared between program and data space and is 2048KB in size. L2 memory can also be configured as mapped RAM, cache, or some combination of the two. The C64x+ Megamodule also has a 32-bit peripheral configuration (CFG) port, an internal DMA (IDMA) controller, a system component with reset/boot control, interrupt/exception control, a power-down control, and a free-running 32-bit timer for time stamp. The peripheral set includes: an inter-integrated circuit bus module (I2C); two multichannel buffered serial ports (McBSPs); an 8-bit Universal Test and Operations PHY Interface for Asynchronous Transfer Mode (ATM) Slave [UTOPIA Slave] port; two 64-bit general-purpose timers (also configurable as four 32-bit timers); a user-configurable 16-bit or 32-bit host-port interface (HPI16/HPI32); a peripheral component interconnect (PCI); a 16-pin general-purpose input/output port (GPIO) with programmable interrupt/event generation modes; an 10/100/1000 Ethernet media access controller (EMAC), which provides an efficient interface between the TCI6482 DSP core processor and the network; a management data input/output (MDIO) module (also part of the EMAC) that continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system; a 4-bit transmit, 4-bit receive VLYNQ interface; a glueless external memory interface (64-bit EMIFA), which is capable of interfacing to synchronous and asynchronous peripherals; and a 32-bit DDR2 SDRAM interface. The I2C ports on the TCI6482 device allows the DSP to easily control peripheral devices and communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may be used to communicate with serial peripheral interface (SPI) mode peripheral devices. The VLYNQ interface provides a standard high-speed serial interface to a variety of TI devices that can supplement the processing power or external connectivity of the TCI6482 device. This supports host-to- peripheral or peer-to-peer communication modes. The TCI6482 DSP has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows® debugger interface for visibility into source code execution. The C64x+ CPU has two tightly coupled Rake/Search Accelerators (RSAs) for Code Division Multiple Access (CDMA) to assist with chip rate processing in Base Transceiver Systems (BTS).
