The Decorated Diagram: Harvard Architecture and the Failure of the Bauhaus Legacy Klaus Herdeg

After a five-month sojourn in Rome, the author Henry James departed with “an acquired passion for the place.” The year was 1873, and he wrote eloquently of his ardor, expressing appreciation for the beauty in the “solemn vistas” of the Vatican, the “gorgeous” Gesù church, and the “wondrous” Villa Madama. Such were the impressions of a Bostonian who spent much of his adult life in Europe. By contrast, in June of 1885, the young Boston architect Herbert Langford Warren wrote to his brother about how he was “glad to be out of Italy.” He had just concluded a four-month tour there. He had also visited England and France, and he was convinced that the architecture and sculpture of those countries were superior to what he had seen in Italy, although he admired Italian Renaissance painting. When still in Rome, he told his brother how disagreeable he found the “Renaissance architecture in Italy contemporary with Michael Angelo and later under Palladio and Vignola,” preferring the work of English architects Inigo Jones and Wren. Warren appreciated some aspects of the Italian buildings of the 15th and early 16th centuries, but he considered the grandeur and opulence of later Renaissance architecture especially distasteful.

The experiment circuit is divided into two parts: fixed and non-fixed in a synthetical teaching experiment for SCM.The fixed part is made of printed circuit board in its auxiliary device, the non-fixed part is lapped on the bread board by the experimenters .Above contents include:(1) system storage structure is non fixed, which using the jumper switch K1, the system structure may become the Princeton structure, or Harvard architecture or no RAM structure;(2) system storage capacity is non fixed, which using the jumper switch K1,K2, the chip EPROM or RAM is arbitrarily selected by experiment system according to the needs. Experiences show: this auxiliary device improves the flexibility and versatility,saves time, strengthens the experimenter’s operational ability and improves the success rate for the SCM experiment.

Harvard Architecture

This paper is delineating the design and implementation of high performance, synthesizable 32-bit pipelined Reduced Instruction Set Computer (RISC) Core. The design of the Harvard Architecture based 32-bit RISC Core involves design of 32-bit Data-path Unit, Control Unit, 32-bit Instruction Memory, 32-bit Data Memory, Register file with each register of size 32 bit. The processor is divided into Fetch, Decode, Execute and Write Back block in order to implement a four-stage pipeline. A 2*16 LCD is connected to the processor IO block to show the instruction execution sequence for demonstration in FPGA. The RISC Core is designed using Verilog HDL and VHDL and is tested in ISIM Simulator. The implementation of the processor is done in a Spartan 3E Starter Board using Xilinx ISE 14.7. All of the instructions incorporated with the processor have been tested successfully both in simulation and hardware implementation in FPGA.DOI: http://dx.doi.org/10.3126/njst.v15i1.12021 Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 81-88
