Bit-serial architecture a single N-bit parallel processor. Bit-serial architecture In digital logic applications, bit-serial architectures send data one bit at a time, along a single wire, in contrast to bit-parallel word architectures, in which data values are sent all bits or a word at once along a group of wires. All computers before 1951, and most of the early massive parallel processing machines used a bit-serial architecture—they were serial computers. Bit-serial architectures were developed for digital signal processing in the 1960s through 1980s, including efficient structures for bit-serial multiplication and accumulation. Often N serial processors will take less FPGA area and have
Massively parallel signature sequencing Massively parallel signature sequencing Massive parallel signature sequencing (MPSS) is a procedure that is used to identify and quantify mRNA transcripts, resulting in data similar to serial analysis of gene expression (SAGE), although it employs a series of biochemical and sequencing steps that are substantially different. MPSS is a method for determining expression levels of mRNA by counting the number of individual mRNA molecules produced by each gene. It is "open ended" in the sense that the identity of the RNAs to be measured are not pre-determined as they are with gene expression microarrays. A sample of mRNA are first
