Sample text

Signal processing algorithms are examples of this type of algorithm. The SPE utilizes the existing components of the core to bring improved performance with minimum additional complexity of the core and easier integration with existing tools and 38 Chapter 3 software. From a user perspective the most visible aspect of the core with SPE APU is that the registers are shared with the basic core and extended to 64 bits. The pipeline for instruction and data fetch are also extended to 64 bits for optimal transfer of data through the SIMD.

Some of the basic rules to consider in this phase are: • • For a fixed cost, maximize performance For a fixed performance, minimize cost Step 2 e Select the hardware components required for the system In many systems, a general purpose processor (GPP), field programmable gate array (FPGA), microcontroller (uC), or DSP is not used as a single-point solution. This is because designers often combine solutions, maximizing the strengths of each device (Figure 3-1). One of the first decisions that designers often make when choosing a processor is whether they would like a software programmable processor in which functional blocks are developed in software using C or assembly, or a hardware processor in which functional blocks are laid out logically in gates.
