description
fetches VelociTI advanced very-long instruction words (VLIW) (256 bits wide) supply eight 32-bit instructions eight functional units during every clock cycle. VelociTI VLIW architecture features controls which eight units have supplied with instructions they ready execute. first every 32-bit instruction determines next instruction belongs same execute packet previous instruction, whether should executed following clock part next execute packet. Fetch packets always bits wide; however, execute packets vary size. variable-length execute packets memory-saving feature, distinguishing 'C67x from other VLIW architectures. features sets functional units. Each contains four units register file. contains functional units .L1, .S1, .M1, .D1; other contains units .D2, .M2, .S2, .L2. register files contain 32-bit registers each total general-purpose registers. sets functional units, along with register files, compose sides (see functional block diagram Figure four functional units each side freely share registers belonging that side. Additionally, each side features single data connected registers other side, which sets functional units access data from register files opposite sides. While register access functional units same side register file service units single clock cycle, register access using register file across supports read write cycle. 'C67x executes 'C62x instructions. addition 'C62x fixed-point instructions, eight functional units (.L1, .M1, .D1, .D2, .M2, .L2) also execute floating-point instructions. remaining functional units (.S1 .S2) also execute LDDW instruction which loads bits side total bits cycle. Another feature 'C67x load/store architecture, where instructions operate registers opposed data memory). sets data-addressing units (.D1 .D2) responsible data transfers between register files memory. data address driven units allows data addresses generated from register file used load store data from other register file. 'C67x supports variety indirect-addressing modes using either linear- circular-addressing modes with 15-bit offsets. instructions conditional, most access registers. Some registers, however, singled support specific addressing hold condition conditional instructions condition automatically "true"). functional units dedicated multiplies. functional units perform general arithmetic, logical, branch functions with results available every clock cycle. processing flow begins when 256-bit-wide instruction fetch packet fetched from program memory. 32-bit instructions destined individual functional units "linked" together bits least significant (LSB) position instructions. instructions that "chained" together simultaneous execution eight total) compose execute packet. instruction breaks chain, effectively placing instructions that follow next execute packet. execute packet crosses fetch-packet boundary (256 bits wide), assembler places next fetch packet, while remainder current fetch packet padded with instructions. number execute packets within fetch packet vary from eight. Execute packets dispatched their respective functional units rate clock cycle next 256-bit fetch packet fetched until execute packets from current fetch packet have been dispatched. After decoding, instructions simultaneously drive active functional units maximum execution rate eight instructions every clock cycle. While most results stored 32-bit registers, they subsequently moved memory bytes half-words well. load store instructions byte-, half-word, word-addressable.
