This device provides significantly lower power than other members of the TMS320C6000™ platform of DSPs. The device enables OEMs and ODMs to quickly bring to market devices with the following features through the maximum flexibility of a fully integrated, mixed processor solution: • Robust operating systems • Rich user interfaces • High processor performance The device DSP core uses a 2-level cache-based architecture. The level 1 program cache (L1P) is a 32- KB direct mapped cache, and the level 1 data cache (L1D) is a 32-KB 2-way, set-associative cache. The level 2 program cache (L2P) consists of a 256-KB memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two. Although the DSP L2 is accessible by other hosts in the system, an additional 128KB of RAM shared memory is available for use by other hosts without affecting DSP performance. For security-enabled devices, TI’s Basic Secure Boot lets users protect proprietary intellectual property and prevents external entities from modifying user-developed algorithms. By starting from a hardware- based “root-of-trust”, the secure boot flow ensures a known good starting point for code execution. By default, the JTAG port is locked down to prevent emulation and debug attacks; however, it can be enabled during the secure boot process during application development. The boot modules are encrypted while sitting in external nonvolatile memory, such as flash or EEPROM, and are decrypted and authenticated when loaded during secure boot. This protects customers’ IP and lets them securely set up the system and begin device operation with known, trusted code. Basic Secure Boot uses either SHA-1 or SHA-256, and AES-128 for boot image validation. Basic Secure Boot also uses AES-128 for boot image encryption. The secure boot flow employs a multilayer encryption scheme which not only protects the boot process but offers the ability to securely upgrade boot and application software code. A 128-bit device-specific cipher key, known only to the device and generated using a NIST-800-22 certified random number generator, is used to protect customer encryption keys. When an update is needed, the customer uses the encryption keys to create a new encrypted image. Then the device can acquire the image through an external interface, such as Ethernet, and overwrite the existing code. For more details on the supported security features or TI’s Basic Secure Boot, refer to the TMS320C674x/OMAP-L1x Processor Security User’s Guide (SPRUGQ9). The peripheral set includes: • A 10/100 Mb/s Ethernet media access controller (EMAC) with a management data input/output (MDIO) module • One USB2.0 OTG interface • One USB1.1 OHCI interface • Two I2C Bus interfaces • One multichannel audio serial port (McASP) with 16 serializers and FIFO buffers • Two multichannel buffered serial ports (McBSPs) with FIFO buffers • Two SPI interfaces with multiple chip selects • Four 64-bit general-purpose timers each configurable (one configurable as a watchdog) • A configurable 16-bit HPI • Up to 9 banks of 16 pins of general-purpose I/O (GPIO) with programmable interrupt and event generation modes, multiplexed with other peripherals Copyright © 2009–2013, Texas Instruments Incorporated TMS320C6748 Fixed- and Floating-Point DSP 3 Submit Documentation Feedback Product Folder Links: TMS320C6748 |
