The TMS34010: an embedded microprocessor - IEEE Micro

چکیده
Texas Instruments he TMS34010 is a high-performance 32-bit microprocessor with special instructions and hardware for handling the bit-field data and address manipulations often associated with computer graphics. With integrated control and addressing for dynamic random access memory (DRAM), it supports a lower system cost than would normally be associated with a 32-bit microprocessor. Internal features such as an instruction cache, thirty-one 32-bit registers, and an independent memory control unit maintain a high degree of parallelism while efficiently utilizing lower cost DRAM. Embedded processing for graphics was the target application for the 34010 from its inception. This led to a set of cost and performance decisions that are applicable to a wide variety of systems in addition to graphics systems. The chip contains over 180,000 transistors fabricated in 1.8-pm CMOS, consuming approximately one-half watt while executing in excess of six million instructions per second. In addition to a full 32-bit microprocessor core, the 34010 contains on-chip video random access memory (VRAM) display support, DRAM control, and a host interface.
