Chapter 1 SPRUFX5A–October 2010–Revised November 2010 System Control 1.1 Introduction The TMS320C5515 digital signal processor (DSP) contains a high-performance, low-power DSP to efficiently handle tasks required by portable audio, wireless audio devices, industrial controls, software defined radio, fingerprint biometrics, and medical applications. The C5515 DSP consists of the following primary components: • A C55x CPU and associated memory • FFT hardware accelerator • Four DMA controllers and

Introduction www.ti.com 1.1.2 CPU Core The C55x CPU is responsible for performing the digital signal processing tasks required by the application. In addition, the CPU acts as the overall system controller, responsible for handling many system functions such as system-level initialization, configuration, user interface, user command execution, connectivity functions, and overall system control. Tightly coupled to the CPU are the following components: • DSP internal memories – Dual-access RAM (DA

www.ti.com Introduction Note that for the FFT routines, output data is dependent on the return value (T0). If return = 0 output data is in-place, meaning the result will overwrite the input buffer. If return =1, output data is placed in the scratch buffer. The 32-bit input and output data consist of 16-bit real and 16-bit imaginary data. If only real data is used, the imaginary part can be zeroed. The Scale flag determines if the butterfly output is divided by 2 to prevent overflow at the expens

During the mobile SDRAM initialization, the device issues the load mode register initialization command to two different addresses that differ in only the BA0 and BA1 address bits. These registers are the Extended Mode register and the Mode register. The extended mode register exists only in mSDRAM, and not in non-mSDRAM. If a non-mobile SDRAM memory ignores bits BA0 and BA1, the second loaded register value overwrites the first
