Assignee:

iKoa Corporation - Menlo Park CA

International Classification:

G06F 9/44

US Classification:

717108

Abstract:

A method for specifying stateful, transaction-oriented systems is provided. The method initiates with designating a plurality of primitive FlowModules. The method includes defining at least one FlowGate within each of the plurality of FlowModules, wherein each FlowGate includes a non-interruptible sequence of procedure code, a single point of entry and is invoked by a named concurrent call. An Arc is designated from a calling FlowGate to a called FlowGate and a Signal is generated for each named invocation of the called FlowGate. A Channel is defined for carrying the Signal. Methods for synthesizing a semiconductor device and routing signals in the semiconductor device are provided.

Abstract:

A graphics controller chip has an integrated graphics memory. A wide data interface is provided to a RAM array storing graphics pixel data in the graphics memory. The wide data interface provides 256 bits of data during normal writes, but in a block-write mode the wide data interface is split into two sections. One section contains 128 bits of data, while a second section contains 128 mask bits. The data is replicated to eight half-width columns in the RAM array, while the mask bits disable writing some of the data to the RAM. Separate byte-mask bits can be provided for disabling bytes during normal mode writes, but these byte-mask bits cause multiple copies of the data to be disabled. Thus the mask bits in the second section are more useful as they can disable any individual byte in any of the eight columns. A block write of 64 2-byte pixels can be performed in a single step, as no color-data register and no mask register is needed.
